If the YASKAWA Inverter indicates a speed deviation (dEV), check the load.
What to do if YASKAWA Inverter displays overvoltage (OV)?
If the YASKAWA Inverter is showing an overvoltage (OV) error because the main circuit DC voltage has exceeded the OV level, try extending the deceleration time. If the issue persists, consider adding a braking circuit.
How to fix YASKAWA CIMR-SSA overload (OL2)?
If your YASKAWA Inverter displays an inverter overload (OL2) message, it means the inverter output has exceeded the overload level. To resolve this, try reducing the load. Additionally, consider extending the acceleration time.
Why is my YASKAWA Inverter showing an overheat alarm (OH)?
If the YASKAWA Inverter is overheating, indicated by an (OH) alarm, the transistor heatsink temperature has likely exceeded the allowable value (95°C). You should check the heatsink and ambient temperature. Also, inspect the filter and the fan for any issues.
What causes ground fault (GF) on YASKAWA Inverter?
If the YASKAWA Inverter indicates a ground fault (GF), and the inverter output grounding current has exceeded 50% of the inverter's rated current, check the motor insulation for any signs of deterioration. Also, verify that the connection between the inverter and the motor is not damaged.
What to do if YASKAWA Inverter shows load open-phase (LF)?
If the YASKAWA Inverter displays a load open-phase (LF) error, and the inverter output has an open phase, start by checking the output wiring. Also, check the motor impedance and re-tighten the input terminal screws.
How to troubleshoot transmission fault with transmission option (bUS) on YASKAWA CIMR-SSA Inverter?
If the YASKAWA Inverter shows a transmission fault with transmission option (bUS), check the transmission devices and the transmission signals.
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.
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 does control circuit fault 1 (CPF00) mean on YASKAWA CIMR-SSA?
If the YASKAWA Inverter displays a 'Control circuit fault 1 (CPF00) (Digital operator transmission fault)' error, where transmission between the inverter and digital operator cannot be established 5 seconds after supplying power, insert the digital operator connector again. Also, check the control circuit wiring and replace the control card.
