Enabling the fixed stop alarms
The machine parameter:
MD37050 FIXED_STOP_ALARM_MASK
can be used to set the enabling of the fixed stop alarms as follows:
MD 37050 = 0 Fixed stop not reached (suppress Alarm 20091)
MD 37050 = 2 Fixed stop not reached ( suppress alarm 20091) and
fixed stop aborted (suppress alarm 20094)
MD 37050 = 3 Fixed stop aborted (suppress alarm 20094)
All other permissible values of 7 or less do not suppress any alarms.
Using the parts program command NEWCONF a new setting can be activated.
Terminal 663 with MD37002 controllable
With the machine parameter:
MD37002 FIXED_STOP_CONTROL
the response to pulse blocking on the fixed stop is controllable.
Deleting the pulses by terminal 663 or the IS "Pulse enable" 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.
