A number of fault codes help the user identify faults on the drive. nCL is the code for the network comm loss fault. This fault is caused when communications with the AutoMax network have been lost. In order to correct this fault, first check the network cabling from the network master to the network option board. Then check that the network master is operating correctly. nld is the code for the Identification Request not yet performed fault. This fault is caused when the drive has started but the Identification Result = Zero. In order to correct this fault, reset the fault, perform another Identification request, and restart the drive. OCA is the code for the overcurrent at acceleration fault. This fault is caused by either an overcurrent condition that occurred while the drive was accelerating, or a too-short acceleration time. In order to correct this fault, increase the acceleration time. OCb is the code for the overcurrent at DC braking fault. This fault is caused by a DC voltage that is too high. In order to correct this fault, check parameters H.006 and H.007.
