Siemens SINUMERIK 804D sl Function Manual

Detailed Description
2.3 Continuous-path mode, exact stop and LookAhead (B1)
NC/PLC Interface Signals (Z1)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2-69
2.2.4 Signals from axis/spindle (DB31, ...)
DB31, ...
DBX60.2 - DBX60.3 Encoder limit frequency exceeded 1
Encoder limit frequency exceeded 2
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The limit frequency set in the machine data:
MD36300 $MA_ENC_FREQ_LIMIT (encoder limit frequency)
has been exceeded.
The reference point for the position measuring system involved has been lost (IS:
Referenced/synchronized has a signal state 0). Closed loop position control is no longer possible.
Spindles continue to run with closed-loop speed control. Axes are stopped with a fast stop (with
open-circuit position control loop) along a speed setpoint ramp.
Signal state 0 or
edge change
1 → 0
The limit frequency set in machine data:
MD36300 $MA_ENC_FREQ_LIMIT
is no longer exceeded
(encoder frequency < ENC_FREQ_LIMIT_LOW).
For the edge change 1 → 0, the encoder frequency must have fallen below the value of machine
data:
MD36302 $MA_ENC_FREQ_LIMIT_LOW
2.3 2.3 Continuous-path mode, exact stop and LookAhead (B1)
2.3.1 Signals from channel (DB21, ...)
DB21, ...
DBX36.3 All axes stationary
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
All axes assigned to the channel are stationary with interpolator end.
No other traversing movements are active.
