User Manual of EM760 High-Performance Inverter VF separation is usually applied in induction heating, inverter power supply, torque motor control, etc. When VF separation control is selected, the output voltage can be set by the function code F05.08 or according to the analog, high-speed pulse, PID or communication settings. For non-digital settings, 100% of each setting corresponds to the rated voltage of the motor. When the percentage set by the analog output is negative, the set absolute value will betaken as the valid set value. F05.07=0: digital setting of VF separation voltage (F05.08) The VF separation output voltage depends on the digital setting of VF separation voltage (F05.08).
F05.07=1: AI1 F05.07=2: AI2 F05.07=3: AI3 F05.07=4: high-frequency pulse (X7) The VF separation output voltage depends on AI/high-speed pulse (percentage) * rated motor voltage. F05.07=5: process PID The VF separation output voltage depends on the process PID function output, as described in 6.2.3.1. F05.07=6: communication setting The VF separation output voltage depends on the communication.
● Ifthe master-slave communication (F10.05=1) is enabled and the inverter works as the slave (F10.06=0), the VF separation output voltage is “700FH (master-slave communication setting) * F01.02 or others (rated voltage of the motor) * F10.08 (slave receiving proportional coefficient) * rated motor voltage”. The 700FH data range is 0.00% to 100.00%. ● For general communication (F10.05=0), the VF separation output voltage is “7006H (voltage setting of the VF separation mode) * rated motor voltage”, and the 7006H data range is 0.00% to 100.00%. 203 Function code Function codename Parameter description Unit Default setting Attribute F05.07 Voltage source of VF separation mode 0:
