Custom V/f Pattern

Set up a custom V/f pattern by setting parameter E1-03 to “F”, and then setting the values in parame-

ters E1-04 to E1-13.

* For 460V class units, the value is twice that of 230V class units. For 575V class units the value is 2.5 times the 230V value.

Increasing the voltage in the V/f pattern increases motor torque. However, when setting a custom

V/f pattern, increase the voltage gradually while monitoring the motor current, to prevent:

· Inverter fault trips as a result of motor overexcitation

· Motor overheat or excessive vibration
