50℃ (Provided no ice or frost has formed.) 90% RH or less (Provided no condensation has formed.) Storage temperature -20 - 65℃ Environment There should be no corrosive or flammable gas, oil residue, dust, etc Altitude/Vibrations Altitude of 1,000 m or lower/vibrations of 5.9 m/sec² (= 0.6 g) or less Environment Ambient pressure 70 - 106 kPa vi Usage Precautions  Wiring  Do not install a phase advance capacitor, surge filter, or radio noise filter on the output of the inverter  Connect the output side terminals (R, S and T) in the correct order  The inverter may be damaged if these terminals are incorrectly connected  Be careful Connecting the input side (terminals DCP, DCN) into the output side (terminals R, S, T) incorrectly may damage the inverter Caution Wiring or inspection must be performed by a qualified technician   Starting the Inverter    Do not supply a voltage to any terminal if it exceeds the range outlined in the manual Excess voltage may damage the inverter Usage   Fully install the inverter before wiring Do not modify the interior workings of the inverter Disposal  Dispose of the inverter according to your local regulations regarding the disposal of industrial waste  Recycle all recyclable components contained in this inverter to preserve energy and resources  The packing materials and metal components of this product are recyclable in most areas Plastic parts are recyclable or may be burned in a controlled environment, depending on local regulations Cleaning  Turn off the inverter prior to cleaning Clean the inverter with a dry cloth Never use water or a wet cloth to clean the inverter vii Usage Precautions  Long-term Storage If you are not planning on using the inverter for a long period of time, store it under the following conditions:  Store the inverter in an area which complies with the recommended storage environment guidelines (See page vi.)  If the storage period exceeds three months, store the inverter at a temperature of between -10 and 30˚C to prevent thermal degradation of the electrolytic capacitor  Package the inverter to prevent moisture from accumulating inside it Ensure that the inverter is stored with a relative humidity of less than 70% by placing a desiccant (silica gel) packet inside the packaging  If the inverter is exposed to humidity or dust (e.g if it is installed on construction equipment), detach it from the equipment before storing it under the conditions set forth on page vi Caution If the inverter is not supplied with electricity for a long period of time, the electrolytic condenser may suffer from thermal degradation To prevent this from happening, connect the power supply to the inverter for 30 - 60 minutes at least once a year Do not perform any wiring or other operation on the output (secondary) side of the inverter viii Table of Contents Table of Contents ABOUT THIS MANUAL III SAFETY PRECAUTIONS IV USAGE PRECAUTIONS VI TABLE OF CONTENTS IX PRECAUTIONS 1-1 1.1 Product Overview 1-1 1.2 Products with a Built-in Braking Resistor (capacity = less than 3.7 kW) 1-1 WINDER/UNWINDER OPERATION 2-1 2.1 Overview 2-1 2.2 General Configuration 2-3 2.3 Main Speed Command Section 2-8 2.4 Tension Command Section 2-11 2.5 Web PID Controller Section 2-16 2.6 Diameter Computation Section 2-25 2.7 Final Speed Computation Section 2-33 2.8 Analog Output Section 2-40 2.9 Final Tension Computation Section 2-41 2.10 Web Break Detection Section 2-42 2.11 Torque Limit Computation Section 2-44 2.12 Web Function without Diameter Computation Section 2-47 CAPSTAN OPERATION 3-1 3.1 Overview 3-1 3.2 General Configuration 3-3 3.3 Main Speed Command Section 3-4 3.4 Web PID Controller Section 3-4 3.5 Analog Output Section 3-4 3.6 Web Break Detection Section 3-4 3.7 Material Thickness Computation Section 3-5 ix Table of Contents 3.8 Final Speed Computation Section 3-11 OTHER FUNCTIONS 4-1 APPLIED FUNCTIONS 5-1 x 5.1 Setting the Override Frequency Using the Aux Frequency Command 5-1 5.2 Jog Operation (Jog-operating the Inverter) 5-5 5.3 Up – Down Operation 5-9 5.4 Wire Operation (Operating the Inverter with the Push Button or Equivalent) 5-11 5.5 Safe Operation Mode (Using the Terminal Input to Limit Operation) 5-12 5.6 Dwell Operation (Operating the Inverter in Dwell Mode) 5-14 5.7 Slip compensation operation 5-16 5.8 PID Control 5-18 5.9 Auto-tuning 5-25 5.10 V/F Operation Using the Speed Sensor 5-31 5.11 Sensorless (I) Vector Control 5-32 5.12 Sensorless (II) Vector Control 5-34 5.13 Vector Control 5-38 5.14 Torque Control (Controlling the Torque) 5-45 5.15 Droop Control 5-47 5.16 Speed/Torque Switchover 5-47 5.17 Kinetic Energy Buffering 5-48 5.18 Energy Saving Operation 5-49 5.19 Speed Search Operation 5-50 5.20 Automatic Restart Operation 5-54 5.21 Operation Sound Selection 5-56 5.22 Second Motor Operation (with One Inverter) 5-58 5.23 Bypass Operation 5-60 5.24 Cooling Fan Control 5-61 5.25 Input Power Frequency Selection 5-62 5.26 Inverter Input Voltage Selection 5-62 5.27 Reading, Writing, and Saving Parameters 5-62 5.28 Parameter Initialization 5-63
