What does External Fault EF mean on my YASKAWA A1000 Controller?
The YASKAWA Controller External Fault (EF) alarm indicates that a forward and reverse command were input simultaneously for longer than 500 ms, which stops a running motor. You should check the sequence to ensure that the forward and reverse inputs are not set at the same time.
Why does my YASKAWA A1000 Controller show Safe Disable Hbb?
If your YASKAWA Controller displays a Safe Disable (Hbb) error, it means that both Safe Disable inputs are open, which safely disables the drive output and prevents the motor from starting. Check why the upper controller’s safety device disabled the drive, remove the cause, and restart. Also, check the wiring. If the Safe Disable function is not utilized, the terminals HC, H1, and H2 must be linked.
What causes a DC Undervoltage Uv1 error on my YASKAWA A1000 Controller?
The YASKAWA Controller DC Undervoltage (Uv1) error appears when the voltage in the DC bus falls below the undervoltage detection level (L2-05). This can occur due to a power supply failure, loss of an input phase, or an inadequate power supply. Check the power supply to ensure it is strong enough.
What to do if YASKAWA A1000 shows External Faults EF1 to EF8?
If the YASKAWA Controller displays External Faults (EF1 to EF8), it means an external fault was triggered by an external device via one of the digital inputs S1 to S8, or the digital inputs are set up incorrectly. To resolve this, find out why the device tripped the EF, remove the cause, reset the fault, and check the functions assigned to the digital inputs.
What to do if my YASKAWA A1000 shows Cannot Reset CrST?
If your YASKAWA Controller displays the Cannot Reset (CrST) error, it means that a fault reset was input while a Run command was active. Turn off the Run command and then reset the drive.
What does End5 mean on my YASKAWA A1000?
The YASKAWA Controller End5 error indicates a Resistance Tuning Error, meaning the calculated resistance value is outside the allowable range. Double-check the data entered for the Auto-Tuning process and check the motor and motor cable connections for faults.
How to fix 'Motor control method and motor do not match' on YASKAWA A1000 Controller?
A 'Motor control method and motor do not match' error on your YASKAWA Controller indicates that the wrong control method is set for the motor. To resolve this, check the control mode setting.
What causes a Control Circuit Error on YASKAWA A1000 Controller?
A 'Control Circuit Error' on a YASKAWA Controller suggests there is a connection error between the control board and the drive. Check the connection to resolve this issue.
What does Ground Fault GF mean on my YASKAWA A1000?
If the YASKAWA Controller displays a Ground Fault (GF) error, it indicates that the ground leakage current has exceeded 50% of the drive's rated output current, there is broken cable or motor insulation, or there is excessive stray capacitance at the drive output. To resolve this, check the output wiring and the motor for short circuits or broken insulation, replacing any broken parts. Also, reduce the carrier frequency.
Why is my YASKAWA A1000 showing a Motor Overload oL1 error?
A YASKAWA Controller Motor Overload (oL1) error typically occurs because the motor load is too heavy, the motor is operating at low speed with a heavy load, the cycle times of acceleration/deceleration are too short, or an incorrect motor rated current has been set. To fix this, reduce the motor load, use a motor with external cooling and set the correct motor in parameter L1-01, check the sequence, and verify the rated current setting.
