Error C.
Error C.
This command sets the maximum allowed following error for an axis. This
error is defined as the difference between the real position and the theoret-
ical position of a motion device. The real position is the one reported by
the position sensing device (encoder, scale, etc.) and the theoretical posi-
tion is calculated by the controller each servo cycle. If, for any axes and
any servo cycle, the following error exceeds
the preset maximum allowed
following error, the controller stops motion on all axes and turns power off
to all motors.
The command can be sent at any time
but it has no effect until the UF
(update filter) is received.
If the sign "?" takes place of nn, this command returns the maximum fol-
lowing error value.
