Input AC Supply Voltage
Sets the drive input voltage.
NOTICE: Damage to Equipment. Set E1-01 [Input AC Supply
Voltage] to align with the drive input voltage (not motor
voltage). If this parameter is incorrect, the protective functions
of the drive will not operate correctly and it can cause damage
to the drive.
