Inputs & Outputs
* For 460V class units, the value is twice that of 230V class units.
Increasing the voltage in the V/f pattern increases motor torque, how-
ever, an excessive increase may cause:
· Inverter fault trips as a result of motor overexcitation
· Motor overheat or excessive vibration
Increase voltage gradually while checking the motor current.
