Question

The display on my drive reads E12 and will not allow me to program or run the drive?

Answer

One of the input terminals is configured for an external trip with the corresponding function set to NC. This configuration is common for e-stop circuits and remote trips such as over-pressure, and over-temperature watchdog relays. The circuit must be complete, with the physical NC contact in series with P24 (CM1 on the SJ300) and the assigned terminal associated with the external trip.

If this was not the intent, the terminal with the external trip assignment must be jumpered to P24 (CM1 on the SJ300) completing the circuit. Reset the drive by the Stop/reset button or by cycling power (if cycling power, remember to allow a few minutes for the drive to discharge before turning power back on.) Commence changing parameters to the desired settings.
