What to check if YASKAWA Inverter indicates load short-circuit (SC)?
If the YASKAWA Inverter reports a load short-circuit (SC), check the motor coil resistance and the motor insulation.
How to fix phase Z pulse fault (ZdEV) on YASKAWA CIMR-SSA Inverter?
If the YASKAWA Inverter displays a 'Phase Z pulse fault (ZdEV)' due to excessive speed deviation, check the PG wiring cable and connector. Also, readjust the zero-pulse.
What causes speed deviation (dEV) in YASKAWA CIMR-SSA Inverter?
If the YASKAWA Inverter indicates a speed deviation (dEV), check the load.
What does digital operator fault (OPr) mean on YASKAWA Inverter?
If the YASKAWA Inverter shows a 'Digital operator fault (OPr)' because the digital operator was disconnected during operation by run command from the digital operator, check the wiring cable and the digital operator connection. Also, replace the control card.
