V/f Control with PG
With V/f control with PG, the user must set the motor parameters, V/f pattern, PG Control
Card settings, and then adjust the speed control loop's gain.
5-5-1 Setting the Motor Parameters
H Inverter Input Voltage Setting (E1-01)
Set the Inverter's input voltage (E1-01) to match the power supply voltage; it cannot be changed during
operation. This setting is used as the reference value for functions such as the protection functions.
