17.1.73.5 Masking out touch probe signals
When passing-through material is used, e.g. printed foil, touch probe initiators may respond several
times per cycle. For suppressing such "interference pulses", count values can be selected in
C01074/1
and C01074/2 that are decremented when the touch probe pulse has been received. Only
when the counter content is "0", the synchronisation will be enabled. Please note that the settings
0 and 1 are functionally identical. If 0 or 1 is set, at least one pulse is required to activate the
synchronisation.

17.1.73.6 Process monitoring functions
Following error
The bFollowingErr status output is set to TRUE if the drive cannot follow its setpoint angle.
• Possible causes:
• The centrifugal mass is too high for the set acceleration or deceleration time.
• The torque limit has been reached (load torque > drive torque).
• Remedy: Unload drive or increase torque limit at the servo controller (if the power limits of the
inverter have not yet been reached).
The following error is derived from the angular difference of the setpoint angle integrator minus the
actual angle integrator. The comparison value (following error limit) can be set in C01071/1
.
Angle controller overflow (bPosOverflow = TRUE)
The bPosOverflow status output is set to TRUE if the angular difference that can be displayed device-
internally has been exceeded. Home positions get lost here.
 Tip!
If an error response is to be triggered in case of a following error and/or angle controller
overflow, connect the corresponding status output with a free bSetError input of the
SB LS_SetError_2
and parameterise the requested error response for this input in C00581.
