10.5.18 Monitoring functions of axis
The static monitoring functions with reference to a machine axis are:
Window around the setpoint position within which exact stop coarse is detected.
MD36000: STOP_LIMIT_COARSE (exact stop coarse)
IS: DB31,... DBX60.6 (position reached with exact stop coarse).
Window around the setpoint position within which exact stop fine is detected.
MD 36010: STOP_LIMIT_FINE (exact stop fine)
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.
MD 36020: POSITIONING_TIME (exact stop fine delay time)
Alarm: “25080 Positioning monitoring” and follow-up mode”.
Position tolerance which a standing machine axis may not leave.
MD36030: STANDSTILL_POS_TOL (standstill position tolerance)
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.
MD36040: STANDSTILL_DELAY_TIME (zero speed control delay time)
Alarm: “25040 Zero speed control” and follow-up mode”.
Tolerance window for a standing machine axis while the signal “Clamping
process running” is present at the PLC interface.
MD36050: CLAMP_POS_TOL (clamping tolerance)
IS: DB31,... DBX2.3 (clamping process running)
Alarm: “26000 Clamping monitoring”.
