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.
E1-04 Maximum Frequency
E1-05 Maximum Voltage
E1-06 Motor Base Frequency
E1-07 Middle Output Frequency A
E1-08 Middle Output Voltage A
E1-09 Minimum Output Frequency
E1-10 Minimum Output Voltage
E1-11 Middle Output Frequency B
E1-12 Middle Output Voltage B
E1-13 Motor Base Voltage
Be sure to satisfy the following conditions for setting
parameters E1-04 to E1-13:
E1-09 ≤ E1-07 ≤ E1-06 ≤ E1-11 ≤ 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
