Once the "Fixed stop reached" status has been detected, the traversing task "Travel to fixed
stop" is ended. The program advances to the next block depending on the task
parameterization. The drive remains in fixed stop until the next positioning task is processed
or the system is switched to jog mode. The clamping torque is therefore also applied during
subsequent waiting tasks. The continuation condition CONTINUE_EXTERNAL_WAIT can be
used to specify that the drive must remain at the fixed stop until a step enabling signal is
applied externally.
As long as the drive remains in fixed stop, the position setpoint is adjusted to the actual
position value (position setpoint = actual position value). Fixed stop monitoring and controller
enable are active.
Note
If the drive is in fixed stop, it can be referenced using the control signal "Set reference point."
If the axis leaves the position that it had at detection of the fixed stop by more than the
selected monitoring window for the fixed stop p2635, then the status bit r2683.12 is reset. At
the same time, the speed setpoint is set to zero, and fault F07484 "Fixed stop outside of the
monitoring window" is triggered with the reaction OFF3 (quick stop). The monitoring window
can be set using the parameter p2635 ("Fixed stop monitoring window"). It applies to both
positive and negative traversing directions and must be selected such that it will only be
triggered if the axis breaks away from the fixed stop.
Fixed stop is not reached
If the brake application point is reached without the "fixed stop reached" status being
detected, then the fault F07485 "Fixed stop is not reached" is output with fault reaction
OFF1, the torque limit is canceled and the drive cancels the traversing block.
Note
• The fault can be changed into an alarm (see section "Message configuration"), which
• The target point must be sufficiently far inside the workpiece.
