What causes Er-09 Accelerate on Omron Inverter?
If your Omron Inverter displays an Er-09 Accelerate error, and the motor did not accelerate in the specified time, increase the acceleration time and torque limits. If the motor is connected to the machine, disconnect it.
What should I do if my Omron Inverter is showing an OV DC Bus Overvolt error?
If your Omron Inverter displays an OV DC Bus Overvolt error, it indicates that the DC bus voltage has exceeded the overvoltage detection level. You can increase the deceleration time or connect a braking option. Also, check the power supply and decrease the voltage to meet the inverter’s specifications. Finally, check the braking chopper and resistor.
What does OL1 Motor Overload mean on my Omron VARISPEED F7 Inverter and how to fix it?
If your Omron Inverter is showing an OL1 Motor Overload error, it means the inverter’s I²t value exceeded the motor overload curve. Recheck the cycle time and the size of the load as well as the accel/decel times. Check the V/f characteristics. Also, check the setting of Motor Rated Current Setting.
What does OPE010 V/f Ptrn Setting mean on my Omron VARISPEED F7?
If your Omron Inverter displays an OPE010 V/f Ptrn Setting error, check parameters. A frequency/voltage value may be set higher than the maximum frequency/voltage.
What does CPF00 COM- ERR(OP&INV) mean on my Omron Inverter?
If your Omron Inverter displays a CPF00 COM- ERR(OP&INV) error, disconnect the Digital Operator and then connect it again. Cycle the Inverter power supply. If the issue persists, replace the Inverter.
What does End-3 Rated FLA Alm mean on my Omron VARISPEED F7 Inverter?
If your Omron Inverter displays an End-3 Rated FLA Alm error, check the motor rated current value.
What does CF Out of Control mean on my Omron VARISPEED F7?
If your Omron Inverter displays a CF Out of Control error, it indicates a control fault where a torque limit was reached continuously for 3 seconds or longer during a deceleration stop in Open Loop Vector control. Check the motor parameters.
What causes a PUF DC Bus Fuse Open error on an Omron VARISPEED F7 Inverter?
If your Omron Inverter displays a PUF DC Bus Fuse Open error, it means that the fuse in the main circuit is blown. Check the motor and the motor cables for short circuits or insulation failures (phase-to-phase). Replace the inverter after correcting the fault.
What does UV2 CTL PS Undervolt mean on my Omron Inverter?
If your Omron Inverter displays an UV2 CTL PS Undervolt error, remove all connection to the control terminals and cycle the power to the Inverter. Replace the Inverter.
What causes DEV Speed Deviation on Omron Inverter?
If your Omron Inverter displays a DEV Speed Deviation error, and the speed deviation has been greater than the setting, reduce the load and lengthen the acceleration and deceleration time. Check the mechanical system and the settings. Also, check the sequence and if the brake is opened when the inverter starts to increase the speed.
