Er-09 on a YASKAWA Controller indicates an acceleration error, meaning the motor did not accelerate for the specified acceleration time. To solve this: * Increase the acceleration time C1-01. * Check the torque limits L7-01 and L7-02.
Why does my YASKAWA Controller show a DC overvoltage error?
A DC overvoltage error on your YASKAWA Controller indicates that the DC bus voltage has risen too high. This can occur due to several reasons: * The deceleration time is too short. * Stall prevention is disabled. * The braking chopper or resistor is broken. * Unstable motor control in Open Loop Vector mode. * Too high input voltage. To resolve this, try the following: * Increase the deceleration time. * Enable stall prevention by adjusting parameter L3-04. * Ensure the braking resistor and braking chopper are functioning correctly. * Check the motor parameter settings and adjust torque and slip compensation, AFR, and hunting prevention as needed. * Verify that the power supply voltage meets the drive's specifications.
What causes motor overload on a YASKAWA CIMR-V 4A0011B Controller?
Motor overload on a YASKAWA Controller can occur due to: a heavy motor load, operating the motor at low speed with a heavy load, short acceleration/deceleration cycle times, or an incorrect motor rated current setting. To address this: * Reduce the motor load. * Use a motor with external cooling and set the correct motor in parameter L1-01. * Check the sequence. * Check the rated current setting.
How to fix a ground fault on YASKAWA CIMR-V 4A0011B Controller?
A ground fault on your YASKAWA Controller can be caused by ground leakage current exceeding 50% of the drive's rated output current, broken cable or motor insulation, or excessive stray capacitance at the drive output. Here’s how to address it: * Check the output wiring and the motor for short circuits or broken insulation, and replace any damaged parts. * Reduce the carrier frequency.
What causes DC undervoltage on a YASKAWA CIMR-V 4A0011B?
DC undervoltage on a YASKAWA Controller can occur if the voltage in the DC bus falls below the undervoltage detection level (L2-05), due to a power supply failure, loss of an input phase, or an insufficient power supply. To resolve this: * Check the power supply. * Ensure that the power supply is adequately strong.
What does Er-03 error mean on YASKAWA CIMR-V 4A0011B?
If your YASKAWA Controller displays an Er-03 error, it means that the STOP button was pressed, and Auto-Tuning was canceled. To resolve this, repeat the Auto-Tuning.
What does Er-04 error mean on YASKAWA CIMR-V 4A0011B?
If your YASKAWA Controller displays an Er-04 error, it indicates a resistance fault due to wrong input data, auto tuning exceeding the given time frame, or calculated values being out of range. To resolve this: * Check the input data. * Check the wiring. * Re-enter the data and repeat the Auto-Tuning.
What does Er-11 error mean on YASKAWA Controller?
If your YASKAWA Controller displays an Er-11 error, it indicates a motor speed fault, meaning the torque reference was too high. To resolve this: * Increase the acceleration time (C1-01). * If possible, disconnect the load.
What does Safe Disable fault mean on my YASKAWA CIMR-V 4A0011B?
A Safe Disable fault on your YASKAWA Controller indicates that the drive output is disabled while only one of the Safe Disable inputs is open. This can occur if one channel is internally broken and does not switch off, or if only one channel is switched off by the upper controller. To resolve this: * Check the wiring from the upper controller and make sure that both signals are set correctly by the controller. * If the signals are set correctly and the alarm does not disappear, replace the drive.
What to do if YASKAWA CIMR-V 4A0011B displays 'l Fault'?
If the YASKAWA Controller shows an 'l Fault', it means the torque limit was reached during deceleration for longer than 3 seconds in Open Loop Vector control. This could be due to: an excessively large load inertia, a torque limit set too low, or incorrect motor parameters. To fix this: * Check the load. * Set the torque limit to the most appropriate setting (L7-01 through L7-04). * Check the motor parameters.
