EM500 Open-Loop Vector Control Inverter User Manual 15 Torque Boost Fixed torque boost curve, customer defined V/F curve scaling Start Torque 150%/ 1 Hz (VVF), 150%/ 0.25 Hz (SVC) Torque Control ±8% rated torque (SVC) Accuracy Output voltage remains unchanged basically and input voltage AVR varies when AVR is active Automatic Automatically limit output current to avoid frequently Current Limit overcurrent trip. Brake frequency: 0.01 - Maximum frequency, brake time: 0 - DC Brake 30S Brake current:
0% - 100% rated current Signal Input Communication, preset speed, analog, high-speed impulse Source Reference 10V/20mA Power Supply Terminal Control Power 24V/200mA Supply 7 (standard X1 - X7) + 4 (expansion card X8 - X11) numeric multi-functional input terminals: Numeric Input X7 can be selected as high-speed impulse input terminal Terminal (F02.06=35/38/40); X1 - X6 and X8 - X11 (10 in total) can be used as common digital input terminals. Function 3 (standard AI1 - AI3) + 1 (expansion card AI4) analog input of Input terminals:
and Output Analog Input 1 (AI1) voltage source 0 - 10 input; Terminal 2 (AI2/AI3) voltage source 0 - 10V inputs or current source 0 - 20mA input; 1 (AI4) voltage source -10V - 10V input 2 (standard Y1/Y2) + 1 (expansion card Y3) OC multi-functional outputs and 2 (R1: EA/EB/EC and R2: Numeric Output RA/RB/RC) relay multi-functional outputs. Terminal Maximum output current of OC: 50mA; relay contact capacity: 250VAC/3A or 30VDC/1A. When the relay works, EA-EC and RA-RC are on, but EB-EC and RB-RC are off. Analog Output M1 is with output 0 - 10V only. Terminal M2 is with output 0 - 10V or 0 – 20 mA. LED LED displays relevant information about inverter.
