The static monitoring functions with reference to a machine axis are:
Window around the setpoint position within which exact stop coarse is detected.
S
MD36000: STOP_LIMIT_COARSE (exact stop coarse)
S
IS: DB31,... DBX60.6 (position reached with exact stop coarse).
Window around the setpoint position within which exact stop fine is detected.
S
MD 36010: STOP_LIMIT_FINE (exact stop fine)
S
IS: DB31,... DBX60.7 (position reached with exact stop coarse).
Delay time after which the actual value must have reached the tolerance
window "Exact stop fine" when the setpoint position is reached.
S
MD 36020: POSITIONING_TIME (exact stop fine delay time)
S
Alarm: "25080 Positioning monitoring" and follow-up mode".

MD36030: STANDSTILL_POS_TOL (standstill position tolerance)
S
Alarm: "25040 Zero speed control" and follow-up mode".
Delay time after which the actual value must have reached the tolerance
window "Standstill position tolerance" when the setpoint position is reached.
S
MD36040: STANDSTILL_DELAY_TIME (zero speed control delay time)
S
Alarm: "25040 Zero speed control" and follow-up mode".
