Anti-Rotation & Wear Monitoring Motion Controls 6.1. EXAMPLES OF LINEAR MOTION CONTROLS 6.1.1. End of Travel Limit Switches Inductive proximity sensors or electro-mechanical roller plunger switches can be used as end of travel limit switches. These arrangements are typically used as limits to stop the actuator or reverse the drive motor. Electro-mechanical roller plunger switches triggered by a nut on the lifting screw which depresses the plunger as it passes. Inductive Proximity sensors trigger when the target nut on the lifting screw passes the sensor. The sensor sends a signal to the control circuit. Anti-Rotation Monitor - The inductive proximity sensor generates a series of pulses from the target discs mounted on the circumference of the nut. The nut rotates at the same speed as the worm gear. If the frequency of pulses is lower than a predetermined value or stops then the control system can inform the operator. This can be used to indicate that the system is below speed or a jamming condition has occurred. The above arrangement is for a lifting screw in compression because as the gear wears the nut moves away from the gear and towards the sensor. If an actuator were in tension the target ring for the sensor would be to the right of the sensor, as the nut would move towards the gear. The anti-rotation and wear monitor devices can be supplied together or as separate devices for Power Jacks machine screw actuators. For installation purposes both devices can be accommodated either below the actuator base (as above) or in the actuator's shell cap. Consult Power Jacks for details. Nut connects to worm gear via dowel pins. This allows the nut to rotate with the gear and follow the lifting screw as the thread in the gear wears. note the nut is unloaded. Wear Monitor - Inductive Proximity Sensor looks for the target ring on the nut. As the gear set wears the nut and its target ring move closer to the sensor. The sensor triggers when the ring is in front of the sensor. When trigger the control system indicates that the actuator should be inspected and refurbished.

EXAMPLES OF LINEAR MOTION CONTROLS Motion Controls CMC Spiral Bevel Gearbox RLS51 limit switch provides extreme end of travel limits for each actuator system and a datum reference point for position control. PowerMAX 5000 frequency converter with integral motion control card. Two bookstyle units linked to sychronise a 2 axis system for speed and position control. Two mechanically linked Sym-metric actuator systems are electronically synchronised for speed and position control using the PowerMAX 5000 frequency converter with integral control card. The PowerMAX 5000 controls the systems by controlling the motion of each motor comparing actual and required performance via a closed feedback loop. This is provided by the encoders in each motor feeding back direct to the PowerMAX 5000. Each actuator system is referenced from a datum point signalled by the RLS-51 limit switch on each system. The RLS-51 also provides end of travel limits that are installed for safety. Each frequency converter has an integral motion control card, which are linked together and arranged in a master-slave relationship for control purposes. This type of system is used where mechanical links to all linear motion components are not possible and where complete motion control is required for a specific process. For example a platform lift where a series of precise positions are required along the actuators stroke where the platform must stop for a specified time with variable speeds at the end of each stroke and a certain number of cycles per complete operation. All of which can be programmed into the unit with key user parameters accessible via the control keypad. For advice on specifying the best solution for your application consult Power Jacks Ltd.

It also has a copy function so extra drives can be set-up in seconds. User-Friendly Control panel has a large display showing 4 measurements, menu group, menu item, parameter value and 3 operating conditions simultaneously. It provides access to logically ordered and grouped menus of inverter parameters with values displayed in engineering units and plain English (or chosen language). Fast Reaction The PowerMAX 5000 precise slip compensation works in the whole speed range, including the over- synchronous area) and adapts in less than 3 milliseconds. Precision PowerMAX 5000 determines the correct stable speed that can react in milliseconds (speed adaptation in less than 3ms). Achieved by providing constant torque at all speeds with a 160% overtorque in the whole speed range to 0 rpm. Automatic Motor Adaption Ensures optimal cooperation between inverter and motor by reading and checking values without motor spinning. Inverter Set-Ups User definable inverter/motor set-ups stored in non-volatile memory (4 maximum). Energy Efficient An automatic energy optimizer makes sure the inverter provides the lowest possible energy consumption compared to actual motor load. This can cut energy consumption by up to 10% and cuts noise level drastically. Recyclable The PowerMAX 5000 inverter is 95% recyclable.

MOTION CONTROL 7.1.1.5. Motion Control Card For applications where electronic control of actuator or drive systems is preferred the integral motion control card option is ideal. Power Jacks can supply the inverter with card installed, pre-programmed and tested to perform the control for motion applications. As the control card is integral in the inverter this reduces installation space and wiring and the need for extra external control devices such as PLC. Up to 32 axes can be controlled in a master-slave arrangement for synchronisation or individual control. A mix of rotary and linear motion devices can be controlled in one installation. Operator controls can be via pushbutton and the standard inverter control panel, which is customisable to allow operator key parameters such as target positions, speed, acceleration, etc. or via an HMI (Human Machine Interface) keypad/display which can directly communicate with the inverter on the RS485 port. The other option is to link via the FieldBus option into a machine or factory network central control. The option control card is programmed from a PC using a powerful language specially designed for positioning control with commands based on frequently used control terminology. Power Jacks offer full motion programming so a complete motion package through actuator, gearbox, motor, feedback devices, inverter, and operator panel can be provided. Features 1. User definable motion programs (127 maximum) stored in non-volatile memory. These programs can be selected or automatically activated. Programs transferred to the card via RS485 port to a PC. 2. Communications - via plug in connectors "Phoenix" type. a) Digital inputs - 8, PNP, 0-24 VDC, (further 8 on main inverter card). b) Digital outputs - 8, PNP, 0-24 VDC c) Both digital inputs and ouputs are galvanically isolated in accordance with PELV. d) Direct connection of encoders(2) incremental or absolute - 5 VDC, com, A, A, B, B, Z, Z. i)Incremental: 5V differential, linedriver or RS422, 220 kHz maximum frequency. i)Absolute: SSI signal, Gray code protocol, 8192 max. ppr, 4096 max. revolutions. 3. Inverter 24 VDC power source can supply up to 420 mA including load on the control card. The 5 V supply is generated from the 24 V supply and has a maximum power of 60 mA on the 24 V side. Stacking Machine Two individually motorised actuators electronically sychronised move to set positions to load product to a platform. At the end of the loading cycle the stack is off loaded and the actuators fast return to repeat the operation. Sensors indicate when product is loaded. Key user parameters such as number of product per stack, product size, number of cycles per process run are entered via the inverters keypad display. Position and speed feedback from encoder on motor. Datum point set via proximity sensor with two further sensors as extreme limits. 7.1.1.6. FieldBus Network Card In many applications there is a need to transfer process data as the real-time position of a lift system or the real-time synchronisation deviance of an application. To relay this kind of information a Fieldbus option can be used. Using a Fieldbus option can also help to free up the digital inputs and outputs for other tasks. Two standard protocols are available for the networkcard: Profibus and Devicenet. The motion control and Fieldbus card can be installed in one unit with internal plug in connections. For full information on the network card option consult Power Jacks. Example Installation 139 7.1.2. Rotary Limit Switches 7.1. MOTION CONTROL Motion Control 7.1.2.1. RLS-51 Rotary Cam Limit Switch Power Jacks actuators are used in a wide spectrum of industries for lifting, positioning and materials handling applications. All of which require a level of motion control. Power Jacks RLS-51 series geared cam limit switches are ideal for use as:- • End of travel limit switches to stop or reverse an actuator system. • Mid travel signal providers to allow integration of other process operations. And allow integration of other feedback devices such as potentiometers and encoders inside their compact housing. RLS-51 Features include:- 1. Useable revolutions from 4 to 16,000. 2. 2 to 8 position limit switches. 3. Enclosure IP66 as standard. 4. Mounting options for B14 face, B5 flange and B3 foot mounted. 5.

Illustrated Examples RLS-51 with 8 Limit Switches and foot mounting The switching points for all contacts can be changed commonly by block adjustment- An electric adjusting motor can be retrofitted Analogue feedback systems, e.g. potentiometers, can easily be fitted. The same applies to the pulse generator used as motion indicator for actuator systems. With absolute encoder For safety disengagements positive opening switching contacts are used: for position or incremental encoders to offer highest safety and finest resolution. With motorised adjustmentGear Part With pulse generator and B5 flange mount With potentiometer 140 7.1.2.1.2. RLS-51 Features and Options The RLS-51 geared cam limit switches are universal mechanical switching devices that have been designed for use in conjunction with cam discs on a specific angle of rotation for the indication of a large number of shaft revolutions. These cam discs serve to operate mechanical contacts. Design features include:- Low Friction Planetary Gearing with irreversable, self-locking worm adjustment of the cam discs. Fixed Cam Adjustment in the housing. The adjusting worms of the cam discs are arranged so that they can be accessed from the same direction as the contact connections for optimal accessibility in confined conditions. Adjustment is possible during operation. The simplicity and accuracy of the cam adjustment is unsurpassed. Block Adjustment of all switching contacts jointly is made possible by a single adjusting worm (black) without the switching points of individual switching contacts being altered with respect to each other. Large Cam Disc Diameter for good adjustability and high switching point repeat accuracy. Reinforced Polycarbonate Housing as standard with IP66 protection and a wide operating temperature range. Modular Design allows adaptation to suit individual requirements via intermediate pieces. Maintenance Free gearbox components. Motion Control 7.1. MOTION CONTROL Options • Position indicating plate for block adjustment. • Potentiometer feedback drives (2 available) to suit single and multi-turn potentiometers. • Pulse transmitter with 50 pulses per revolution. • Anti-condensation heater to prevent condensation and excessively low temperatures in switches. • Motor driven contact block adjuster. • Mounting for encoders (incremental and absolute). • Extended drive shaft for feedback devices. • Aluminium housing for harsh environments and fitment of large and heavy encoders, IP 65 enclosure. • Cam discs with a 40 O cam angle can be provided at no extra cost. Standard is 15 O cam angle. Other angles can be manufactured at extra cost on request. Note different cam angles alter the number of useable revolutions from the standard. The 40 O cam has less useable revolutions than a 15 O cam, consult Power Jacks. • Stage Technology Tested Unit can be provided to VBG 70 with test certificates. A 40 O angle cam disc is used for this application. Note The ideal drive for the limit switch is transmitted by a torsionally stiff, flexible coupling with low axial and radial restoring forces. Thereby misalignment and axial displacement are balanced. For radial load ratings and coupling advice consult Power Jacks. 141 7.1.2.1.4. Switching Contacts The contacts can either be connected through screw terminals for a cable cross section of 0.75 mm 2 to 1.5 mm 2 or through flat plugs 6.3 x 0.8 mm or through a printed card with cage tension spring terminals for a cross section of 0.14 to 2.5 mm 2 . For contacts with flat- plug connection, insulated flat - plug receptables must be used at voltages above 25V AC and 60 VDC. 7.1.2.1.3. RLS-51 Performance 7.1.

Due to the slow actuation speed of the switching contacts caused by the high gear reductions, the change-over behaviour of the contacts is affected negatively. From gear size 6 it is therefore recommended to use only the only normally - closed contacts of the switches. Before using analogue feedback systems (e.g. potentiometer) please consult our technical department.
