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
