Terminal 663 with MD37002 controllable
With the machine data:
MD37002 FIXED_STOP_CONTROL
the response in the case of pulse inhibit at the stop is controlled.
Deleting the pulses by terminal 663 or the "Pulse enable" IS DBX31, ...DBX21.7 will not
abort the function. As a result, the drive will press against the fixed stop again without any
further operating action when the machine is restarted.
The rise time of the torque corresponds to the time needed by the current controller of the
drive to reach the limitation again.
If the pulses are deleted when a deselection is active (waiting for PLC acknowledgments),
the torque limit will be reduced to zero. If the pulses are reactivated during this phase, torque
is no longer built up. Once the deselection has been completed, you can continue traversing
as normally.
Basic logic functions: Travel to fixed stop (F1)
