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 1. With a 400 V class drive, the detection level changes for some motor protective functions.

Voltage	E1-01 Setting	Approximate Values
Voltage	E1-01 Setting	ov Detection Level	BTR Operation Level (rr Detection Level) ¹	L2-05 [Undervoltage Detection Lvl (Uv1)]	L2-11 [KEB DC Bus Voltage Setpoint]	L3-17 [DC Bus Regulation Level]
200 V Class	All settings	410 V	394 V	190 V	260 V	375 V
400 V Class	Setting value ≥ 400 V	820 V	788 V	380 V	500 V	750 V
400 V Class	Setting value < 400 V	820 V	788 V	350 V	460 V	750 V

This is the protection function enabled in drives with built-in braking transistors. These values show the level that will trigger the built-in braking transistor.
