Why are my YASKAWA DC Drives showing an Overcurrent?
- C
  Chelsea KingAug 22, 2025
  An overcurrent in YASKAWA DC Drives can occur due to several reasons: * A short circuit or ground fault on the drive output side. * The load being too heavy. * Accel./decel. times that are too short. * Incorrect motor data or V/f pattern settings. * 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 check the output contactor sequence.

What to do if YASKAWA DC Drives display DC Overvoltage?
- S
  Shawn ClarkAug 23, 2025
  If your YASKAWA DC Drives are showing a DC Overvoltage, it means the DC bus voltage is too high. This can be due to: * A deceleration time that is too short. * Stall prevention being disabled. * A broken braking chopper/resistor. * Unstable motor control in OLV. * Too high input voltage. To fix this, increase the deceleration time, enable stall prevention via parameter L3-04, ensure the braking resistor and chopper are working, check motor parameters and adjust torque/slip compensation, and verify the power supply voltage meets the drive's specifications.

What causes a Ground Fault in YASKAWA DC Drives?
- D
  Debbie RobinsonAug 26, 2025
  A ground fault in YASKAWA DC Drives indicates that the ground leakage current has exceeded 50% of the drive's rated output current. This may be due to broken cable or motor insulation, or excessive stray capacitance at the drive output. To address this, check the output wiring and motor for shorts or broken insulation, replacing any damaged parts, and reduce the carrier frequency.

Why is my YASKAWA DC Drives showing a Motor Overload?
- C
  Caleb SanfordAug 27, 2025
  A motor overload in YASKAWA DC Drives can be caused by: * The motor load being too heavy. * Operating the motor at low speed with a heavy load. * Cycle times of accel./decel. being too short. * An incorrect motor rated current setting. To resolve 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.

What causes YASKAWA DC Drives to display a Drive Overload?
- L
  Laura RobersonAug 27, 2025
  A drive overload in YASKAWA DC Drives can occur because: * The load is too heavy. * The drive capacity is too small. * There is 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.

Why do YASKAWA DC Drives show a DC Undervoltage?
- E
  Elizabeth ZimmermanAug 29, 2025
  A DC Undervoltage in YASKAWA DC Drives indicates that the voltage in the DC bus has fallen below the undervoltage detection level (L2-05). This can happen if the power supply has failed, one input phase has been lost, or the power supply is too weak. To fix this, check the power supply and make sure it is strong enough.

How to handle a Control Circuit Fault on YASKAWA DC Drives?
- J
  Jeffrey RosalesAug 30, 2025
  A Control Circuit Fault on YASKAWA DC Drives indicates that there is no terminal board connected to the control board, or the connection is broken. To resolve this, check if the terminal board is installed properly, uninstall and reapply the terminal board, or change the drive.

How to fix Control Circuit Fault to on YASKAWA DC Drives?
- M
  mark87Sep 1, 2025
  A Control Circuit Fault on YASKAWA DC Drives indicates a problem in the drive's control circuit. Try cycling the drive power supply and initializing the drive. If the fault occurs again, replace the drive.

How to resolve Base Block issue on YASKAWA DC Drives?
- K
  Kristy FlemingSep 2, 2025
  The base block issue on YASKAWA DC Drives occurs when the software base block function is assigned to a digital input, and that input is off, preventing the drive from accepting Run commands. To resolve this, check the digital inputs function selection and verify the upper controller sequence.

How to troubleshoot Heatsink Overheat in YASKAWA DC Drives?
- J
  Joshua NelsonSep 4, 2025
  A heatsink overheat in YASKAWA DC Drives can be caused by: * A high surrounding temperature. * A cooling fan that has stopped working. * A dirty heatsink. * Restricted airflow to the heatsink. To fix this, check the surrounding temperature and install cooling devices if needed, inspect the drive's cooling fan, clean the heatsink, and ensure there is adequate airflow around the heatsink.
