F50 Low frequency voltage compensation (Vector mode), C14=000 (Control mode setting)
Performance during low frequency:
Increase the value of F50 to increase the output voltage and low frequency torque.
Decrease the value of F50 to decrease the output voltage and low frequency torque.
• Operating frequency range:
• During low frequency operation:
When the motor output torque is insufficient, increase the value of F50.
When the motor is vibrating excessively, decrease the value of F50.
