My ATV212 faulted and stopped with EPH1. What is that fault?

EPH1 fault on ATV212

ATV212, ATV21

All models and serial numbers

EPH1 is an input phase loss.

  • Verify the wiring connections on all three phases coming into the drive (R/L1-S/L2-T/L3).
  • Measure line to line voltages to make sure they are all present and equal phase to phase.
  • To clear the fault, cycle power.  Turn off the line voltage until the display goes off.  Then turn the voltage back on.
