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 E1-10.
E1-04 Maximum Frequency
E1-05 Maximum Voltage
E1-06 Maximum Voltage Output Frequency
E1-07 Middle Output Frequency
E1-08 Middle Output Voltage
E1-09 Minimum Output Frequency
E1-10 Minimum Output Voltage
E1-13 Motor Base Voltage
Be sure to satisfy the following conditions
for setting parameters E1-04 to E1-10:
E1-09  E1-07 < E1-06  E1-04

* 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,
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
