Slew Drive shuts off during acceleration

Slew drive starts up normally, and begins to swing, but coasts to stop and drive shuts down with code 7510 (FBA A comm loss func).  Could not get code to clear or swing to operate.  Checked CanOPEN card and both status lights looked good.  FEN 31 (encoder card) also had 2 green lights, but tried to remove encoder connectors and still could not get to work.  Per JP’s recommendation, remove LFC and CCL plugs and install jumpers.  Remove network cables from Trolley and Hoist drives.  Restart crane and test swing, and it works normally with no faults.  Plugged back in trolley network cable, and swing would still work.  Plugged in Hoist network cable and Swing drive would fault without Hoist drive even being turned on.  It was determined that there was a fault in the keypad of the Hoist drive.  Replace keypad and crane worked normally.

 

*For notes.  JP determined there was a fault in the communication system (FBA A Field Bus Adapter), but wanted to isolate what it was.  It was a communication fault through the Can Bus system.  By isolating just the swing drive and swing encoder, we could start to determine it was either of those.  If the Hoist keypad hadn’t caused failure, we would have added back the LFC and CCL plugs 1 at a time to determine if it was a communication fault in the drives, or encoders which also communicate through the Can Bus.  Also note that CAN H and CAN L should produce approx 2.5 VDC to “-” on terminal strip.  This could determine if there is a short to ground.  If the voltage is 0 or low, begin unplugging devices until voltage is restored

HUP will not accept Zero Load

After software upfate, in which SCM and CCT were erased, crane would not accept Zero Load during teach in.  Need to repair loadpin, and re teach Zero load.
