Axis monitoring

Static monitoring functions
The static monitoring functions with reference to a machine axis are:
Exact stop coarse
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)
Exact stop fine
Window around the setpoint position within which exact stop fine is detected.
● MD36010 STOP_LIMIT_FINE (exact stop fine)
● IS: DB31,... DBX60.7 (position reached with exact stop coarse)
Delay time exact stop fine
Delay time after which the actual value must have reached the tolerance window "Exact stop
fine" when the setpoint position is reached.
● MD36020 POSITIONING_TIME (delay time exact stop fine)
● Alarm: "25080 Positioning monitoring" and follow-up mode.
Zero speed tolerance
Position tolerance which a standing machine axis may not leave.
● MD36030 STANDSTILL_POS_TOL (standstill tolerance)
● Alarm: "25040 Zero speed control" and follow-up mode.
Delay time zero speed monitoring
Delay time after which the actual value must have reached the tolerance window "Zero
speed tolerance" when the setpoint position is reached.
● MD36040 STANDSTILL_DELAY_TIME (zero speed monitoring delay time)
● Alarm: "25040 Zero speed control" and follow-up mode.
Clamping tolerance
Tolerance window for a standing machine axis while the signal "Clamping active" is present
at the PLC interface.
● MD36050 CLAMP_POS_TOL (clamping tolerance)
● IS: DB31,... DBX2.3 (clamping active)
