36310 ENC_ZERO_MONITORING
- Zero mark monitoring
-
- 1
Description:
This MD is used to activate zero mark monitoring.
For PROFIdrive drives (the corresponding diagnostics system variables are not
currently supplied for incremental measuring systems):
For PROFIdrive, the permissible deviation must be set in the drive, *not* in the NC.
Zero mark monitoring reported by the drive is mapped to the NCK according to the
following rule:
0:
100:
operations, i.e. not only alarm 25020 but also alarms 25000, 25010 etc. are suppressed.
>0
>100:
power ON alarm 25000 (25001).
For absolute measuring systems (MD30240 $MA_ENC_TYPE=4):
Permissible deviation in 1/2 coarse increments between the absolute and the
incremental encoder track (one 1/2 coarse increment is sufficient).

Description:
Tolerance band for axial contour monitoring (dynamic following error monitoring).
The permissible deviation between the real and the modelled following error is entered
in this MD.
The input of the tolerance band is intended to avoid spurious tripping of the dynamic
following error monitoring caused by minor speed fluctuations, which occur during
normal closed-loop control operations (e.g. during first cut).
Following error modelling and thus the input of this MD depend on the position control
gain MD32200 $MA_POSCTRL_GAIN
and, in the case of precontrol or simulation, on the accuracy of the controlled system
model MD32810 $MA_EQUIV_SPEEDCTRL_TIME (equivalent time constant for precontrol of
speed control loop), as well as on the accelerations and velocities used.
36480 AXSPDCTRL_ACT_POS_TOL

Description:
Permissible deviation between actual and setpoint positions of an axis in speed
control mode ("control axis").

0, 0
no zero mark monitoring
no zero mark monitoring together with suppression of all encoder monitoring
but less than 100: direct triggering of power ON alarm 25000 ( or 25001).
attenuated error message: reset alarm 25010 (25011) is output instead of
