User Manual of A90 Series Inverter the VF separation voltage)”, and the 7006H data range is 0.00% to 100.00%, as detailed in Table 0-2. The rise time of VF separation voltage refers to the time for the output voltage to increase from 0 to the rated voltage of the motor. Output voltage Rated voltage of motor VF separation voltage Actual rise time 0 Set rise time Time t Fig. 7-20 Rise Time Description of VF Separation Voltage It is used to compensate for the voltage drop caused by the stator resistor and wire, and improve the low-frequency load capacity. As the load increases, the rotor speed of the motor will decrease.
To make the rotor speed of the motor close to the synchronous speed under rated load, slip compensation can be enabled. When the motor speed is less than the target value, the set value of F05.11 can be increased. ★ : In the case of F05.11=0, slip compensation is invalid. This parameter is valid only for the asynchronous motor.
