Shortcut RU Format RU [axis] = [distance]… Units millimeter Type Axis-Specific Remembered Using [addr#]SS Z
This command sets the servo loop error limit before the motors will be disabled. The value n
, is the distance in millimeters that the internal servo target and the actual position can differ before the motor is disabled. Default is 1 to 2 mm. If spurious disable conditions are encountered, increase this number. For more sensitive crash protection, decrease this number. Prior to MS-2000 version 9.2f and TG-1000 version 3.20 a single value applied to all axes (Tiger card-addressed) but afterwards it is axis-specific. Prior to MS-2000 version 9.2m and TG-1000 version 3.20 only integer values were allowed, but afterwards floating point numbers are allowed and reported.

RU X=5 :A
Sets runaway sensitivity to 5mm on the X axis for 9.2m and later, sets the sensitivity on all axis for 9.2l and earlier.

1RU X=5 :A
Sets runaway sensitivity to 5mm on all axes in card #1 in v3.19 and earlier, would only set the X axis (assuming it's on card #1) on v3.20 and later.
