MD36020 $MA_POSITIONING_TIME (delay time exact stop fine)
After reaching "Exact stop fine", the position monitoring is deactivated.
Note
The smaller the exact stop fine tolerance is, the longer the positioning operation takes and
the longer the time until block change.
Rules for MD setting
MD36010 $MA_STOP_LIMIT_FINE
MD36020 $MA_POSITIONING_TIME
large
can be selected relatively short
small
must be selected relatively long
MD32200 $MA_POSCTRL_GAIN
(servo gain factor)
MD36020 $MA_POSITIONING_TIME
small
must be selected relatively long
large
can be selected relatively short
Effectivity
The position monitoring only operates with active position control and the following axis
types:
•
Linear axes
•
Rotary axes
•
Position-controlled spindles
Fault
If the configured position-monitoring time is exceeded, the following alarm appears:
25080 "Axis <Axis identifier> Position monitoring"
The affected axis is stopped via the configured braking ramp in follow-up mode:
MD36610 $MA_AX_EMERGENCY_STOP_TIME
(Maximum time for braking ramp when an error occurs)
