What does Er-11 mean on my YASKAWA A1000 Controller?
The YASKAWA Controller Er-11 error indicates a motor speed fault, suggesting the torque reference was too high. Increase the acceleration time (C1-01). If possible, disconnect the load.
What does Er-03 mean on my YASKAWA A1000 Controller?
The YASKAWA Controller Er-03 error indicates that the STOP button was pressed and Auto-Tuning was canceled. Repeat the Auto-Tuning.
What does Er-01 mean on my YASKAWA A1000 Controller?
The YASKAWA Controller Er-01 error indicates a motor data fault, meaning the input motor data are not valid (e.g., the base frequency and base speed do not fit). Re-enter the data and repeat Auto-Tuning.
What to do if YASKAWA A1000 Controller shows Overcurrent oC?
When the YASKAWA Controller displays an Overcurrent (oC) error, it indicates a short circuit or ground fault on the drive output, an excessively heavy load, short acceleration/deceleration times, incorrect motor data or V/f pattern settings, or a magnetic contactor switched at the output. To resolve this, check the output wiring and motor for shorts or broken insulation, inspect the machine for damage, verify the drive parameter settings, and examine the output contactor sequence.
Why YASKAWA Recording Equipment shows speed deviation?
Speed deviation in YASKAWA Recording Equipment, when in Control Mode with PG, can occur due to several reasons. It could be that the load is too heavy, requiring you to reduce it. Alternatively, the acceleration and deceleration times may be set too short; in this case, increase these times using parameters C1-01 through C1-08. A locked-up load, inappropriately set parameters F1-10 and F1-11, or an engaged motor brake can also cause this issue. Ensure the motor brake releases properly and check the machine.
What does End7 error mean on YASKAWA A1000 Controller?
If the YASKAWA Controller displays an End7 error, it indicates a No-Load Current Alarm, meaning the entered no-load current value was outside the allowable range, or Auto-Tuning results were less than 5% of the motor rated current. To resolve this, check and correct faulty motor wiring and double-check the data that was entered for the Auto-Tuning process.
What causes Ground Fault GF on YASKAWA A1000?
If the YASKAWA Controller displays a Ground Fault (GF) error, it indicates that ground leakage current has exceeded 50% of the drive's rated output current, cable or motor insulation is broken, or there's excessive stray capacitance at the drive output. To fix it, check the output wiring and motor for short circuits or broken insulation, replace any damaged parts, and reduce the carrier frequency.
What does Control Fault CF mean on YASKAWA A1000 Controller?
If the YASKAWA Controller is showing a Control Fault (CF) error, it means the torque limit was reached during deceleration for longer than 3 seconds in Open Loop Vector control. This can happen if the load inertia is too big, the torque limit is too low, or the motor parameters are wrong. You should check the load, set the torque limit to the most appropriate setting (L7-01 through L7-04), and check the motor parameters.
What to do for Drive Overload oL2 on YASKAWA A1000 Controller?
If the YASKAWA Controller displays a Drive Overload (oL2) error, it means the load is too heavy, the drive capacity is too small, or there's too much torque at low speed. To resolve this, check the load, ensure the drive is adequately sized for the load, and reduce the load or increase the drive size, as the overload capability is reduced at low speeds.
What does External Fault EF on YASKAWA Controller indicate?
If the YASKAWA Controller displays an External Fault (EF) error, it means that forward and reverse commands were input simultaneously for longer than 500 ms, stopping a running motor. To fix this, check the sequence to ensure that forward and reverse inputs are not set at the same time.
