Fig.38 Custom V/f Pattern Programming Curve
Increasing the voltage in the V/f pattern increases the available motor torque. However, when setting a custom V/f
pattern, increase the voltage gradually while monitoring the motor current, to prevent:
Drive faults as a result of motor over-excitation
Motor overheating or excessive vibration
