Interpolation
(INTERPOLATE)
Last Interpolation
Segment
(ENDOF_INTERPOLATE)
The commanded movement for one scan exceeds
the segment that can be commanded to the
MECHATROLINK SERVOPACK, or the speed
feed forward value exceeds the maximum allow-
able speed.
A: Excessive Speed
The axis is ABS infinite length, and the zero point
return (setting) is not completed.
A: Zero Point Unsetting
In servo OFF status A: Servo OFF
An alarm is occurring. −
