The asynchronous dynamometer is used to acquire and control torque and speed. The APA 100’s construction and dimensions are designed according to the unit under test. EMCON communicates with the asynchronous dynamometer via a fieldbus connection. The fieldbus transmits • states (errors, switch positions) • commands (dyno on, dyno off) • actual values (speed, torque) • demand values (speed, torque) as digital signals. The pendulum torque signal necessary for controlling the torque is measured directly at the dynamometer. The load cell is directly connected to the EMCON. If the test bed’s dynamometer is replaced, the load cell has to be re-calibrated. Otherwise measurement errors may occur. EMCON provides various signals to control the test sequence (auxiliary devices ON/OFF, control modes, preheating etc.).
