Block change criterion: Clamping tolerance
After activation of clamp monitoring:
DB31, ... DBX2.3 = 1 (clamping in progress)
the block change criterion for traversing blocks, in which the axis stops at the end of the
block, no longer acts as the corresponding exact stop condition but the configured clamping
tolerance:
MD36050 $MA_CLAMP_POS_TOL
(clamping tolerance for interface signal "clamping active")
Behavior upon releasing of the clamp
If the axis was moved by the clamping process, it is returned by the NC to the position
setpoint after releasing of the clamp and setting of the servo enable state. Repositioning
depends on whether "Follow-up mode" was activated for the axis:
• Without follow-up mode: Repositioning by position controller
• With follow-up mode: Repositioning by interpolator

DB31, ... DBX1.4 (follow-up mode)
Note
The following interface signals can be evaluated by the PLC user program as the criterion for
activation of the "Follow-up mode":
DB31, ... DBX60.6 / 60.7 (position reached with exact stop coarse / fine)
