Function
If you wish the axis to be clamped at the end of the positioning process, the clamping monitoring
can be activated using the IS “Clamping monitoring running” (V380x 0002.3).
This can be necessary because it is possible that during the clamping process the axis has been
pushed off its setpoint position farther than permitted by the standstill tolerance. The amount by
which the setpoint position can be left is specified in MD 36050: CLAMP_POS_TOL (clamping position
tolerance at interface signal “Clamping running“).
See Fig. 2-1
Activation
The clamping position monitoring is activated by the interface signal ”Clamping process running”. It
replaces the standstill monitoring during the clamping process.
The clamping position monitoring is active for axes and a position–controlled spindle.
Effect
If during the clamping process the axis is pushed off its position farther than permitted by the clamping
position tolerance, the following will occur:
 Alarm 26000 ”Clamping position monitoring” is output.
 The axis/spindle concerned is stopped with rapid stop (with open position control loop) via a
speed setpoint ramp. The duration of the braking ramp is defined in
MD 36610: AX_EMERGENCY_STOP_TIME (duration of braking ramp in case of error statuses).
 If the axis/spindle interpolates with other axes/spindles, these will also be stopped by rapid stop
with reduction of the following error (specification of partial position setpoint = 0).
