100: no zero mark monitoring together with suppression of all encoder monitoring
operations, i.e. not
only alarm 25020 but also alarms 25000, 25010 etc. are suppressed.
>0 but less than 100: direct triggering of power ON alarm 25000 ( or 25001).
>100: attenuated error message: reset alarm 25010 (25011) is output instead of
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.

Description: Permissible deviation between actual and setpoint positions of an axis in speed
control mode ("control axis").
This MD has to be adapted to the accuracy of the speed controller as well as the
permissible accelerations and velocities.

Description: Maximum permissible setpoint velocity as a percentage of the maximum axis velocity/
spindle speed.
With MD36520 $MA_DES_VELO_LIMIT, the position setpoint is monitored for abrupt
changes. If the permissible limit value is exceeded, alarm 1016 error code 550010 is
output.
With axes, this machine data refers to MD32000 $MA_MAX_AX_VELO.
