I have a walking beam machine(new project), that has multiple stations; dwell and indexing stations.
1) has an encoder that can tell angle position, but no clutch/brake installed.
2) walking beam is being driven by a motor that has two internal momentarily switches start and stop coil contacts.
3) when the motor is pulsed to start, it starts and stays running till the stop contacts are energized or a fault occurs.
One of the dwell stations can not retract back fast enough before the walking beam trying to index.
Every cycle I get a fault that one of the dwell station did not fully retract far enough to clear the walking beam and assembly stops. I can not slow down the walking beam nor can speed up the dwell stations.
I do not know if any body has some constructive suggestions on the best way to program this part of the walking beam. At this time I tried the following approaches:

I do not know if any body has some constructive suggestions on the best way to program this part of the walking beam. At this time I tried the following approaches:
- Initiate the motor to stop at the beginning of the dwell cycle then after all stations finished working and retracted to their home position start the motor again. This might not be good for the motor to continuously starting and stopping.
- Keep the motor running, as long the dwell stations are not forward and clear the indexing walking beam pathway by not much. This works fine except the fear of walking beam might shear any of the dwell stations assembly keeps me on the edge.
