12.5 E: Motor Parameters
E parameters cover drive input voltage, V/f pattern, and motor parameters.
◆ E1: V/f Pattern for Motor 1
E1 parameters set the drive input voltage and motor V/f characteristics. To switch drive operation from one motor
to another motor, set the V/f characteristics for motor 1.
■ E1-01: Input AC Supply Voltage
No.

Name Description
Default
(Range)
E1-01
(0300)
Input AC Supply Voltage
Sets the drive input voltage.
400 V: 400 V
(400 V Class: 310 - 510 V)
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.
Values Related to the Drive Input Voltage
The value set in E1-01 is the base value that the drive uses for the motor protective functions in Table 12.3. With a
400 V class drive, the detection level changes for some motor protective functions.
