Block-change criterion: Clamping tolerance
After activation of clamp monitoring:(DB31, ... DBX2.3 = 1) 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 with 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
See also interface signal:
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)
