1: General purpose motor (standard fan cooled)

2: Drive dedicated motor with a speed range of 1:10

3: Vector motor with a speed range of 1:100

6: General purpose motor (50 Hz)

The drive may not be able to provide protection when using

multiple motors, even if overload is enabled in L1-01. Set L1-01

to 0 and install separate thermal relays to each motor.

Default: 1

Range: 0 to 3; 6

Leakage Current Filter

Time Constant 1

Leakage Filter 1

Sets the time constant for reducing the sensitivity level when

detecting leakage current. Set in seconds and used when

operating at constant speed.

Note: This parameter is available only when C6-02 is

set to B. To display this parameter, first set

C6-02 = B.

Default: 20.0 s

Min.: 0.0

Max.: 60.0

Leakage Filter 2

Sets the time constant for reducing the sensitivity level when

detecting leakage current. Set in seconds and used during

acceleration and deceleration operation.

Note: This parameter is available only when C6-02 is

set to B. To display this parameter, first set

C6-02 = B.

Default: 1.0 s
