Tolerance band for axial contour monitoring (dynamic following error monitor-
Description:
ing).
The permissible deviation between the real and the modelled following error
is entered in this MD.
The input of the toleran ce 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 posi-
tion control gain MD32200 $MA_POSCTRL_GAIN
and, in the case of precontrol or simulation, on the accuracy of the con-
trolled system model MD32810 $MA_EQUIV_SPEEDCTRL_TIME (equivalent time con-
stant for precontrol of speed control loop), as well as on the accelerations
and velocities used.
36480 AXSPDCTRL_ACT_POS_TOL
mm, degrees Tolerance for speed control mode
-
- -
Permissible deviation between actual and setpoint positions of an axis in
Description:
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.
36520 DES_VELO_LIMIT
% Threshold for setpoint velocity monitoring
-
- -
Maximum permissible setpoint velocity as a percentage of the maximum axis
Description:
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.
With spindles, this MD refers to the lower of the speeds set in
MD35130 $MA_GEAR_STEP_MAX_VELO_LIMIT of the current gear stage and MD35100
$MA_SPIND_VELO_LIMIT.
