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
Tables 5 and 6 are for 240 V class units only. For 480 V class units, multiply the voltage values by 2.
