Set

Positive I Limit

USINT

1

%

The positive current limit value. The value is a
percentage of the lesser of the intermittent (peak)
drive current rating and intermittent (peak) motor
current rating. During runtime, the drive limits
positive current to the lesser of
the Positive Current Limit,
the analog current limit input,
the Intermittent Current rating of the drive, or
the Intermittent Current rating of the motor.
Range: 0 to 100
Default: 100

38

Set

Negative I Limit

USINT

1

%

The negative current limit value. The value is a
percentage of the lesser of the intermittent (peak)
drive current rating and intermittent (peak) motor
current rating. During runtime, the drive limits
positive current to the lesser of
the Negative Current Limit,
the analog current limit input,
the Intermittent Current rating of the drive, or
the Intermittent Current rating of the motor.
Range: 0 to 100
Default: 100

Set

Soft Overtravel

USINT

1

Enables or disables the software overtravel limit
checking.
0 - Disable (default)
