What causes Motor Overload on YASKAWA Controller?
If the YASKAWA Controller is showing a motor overload, it could be due to: * The motor load being too large: Decrease the motor load. * Operating a general-purpose motor with a high load at a lower speed than the rated speed: Use a motor with an external cooling fan and set the correct motor type to L1-01 [Motor Overload (oL1) Protection].
What to do if I get an Option Communication Error on my YASKAWA Industrial Electrical?
An option communication error in YASKAWA Industrial Electrical can occur due to several reasons. Start by checking for wiring errors and repairing any short circuits or disconnected cables. Electrical interference can also cause communication data errors, so examine the control circuit lines, main circuit lines, and ground wiring to minimize interference. Ensure the option is correctly installed in the drive. If the problem persists and the wiring is correct, the option may be damaged and need replacement.
Why am I getting a Control Fault on my YASKAWA Industrial Electrical?
A control fault in YASKAWA Industrial Electrical can be caused by several factors. First, ensure that the motor parameters are set correctly and perform Auto-Tuning again. If the torque limit setting is too low, adjust L7-01 to L7-04 [Torque Limit]. For large load inertia, adjust C1-02, C1-04, C1-06, and C1-08 [Deceleration Times]. If the drive attempts to ramp to stop a machine that doesn't require it, correctly set b1-03 [Stopping Method Selection]. Finally, verify that the motor and drive are wired correctly.
What to do for Braking Transistor Overload Fault in YASKAWA Industrial Electrical?
A braking transistor overload fault in YASKAWA Industrial Electrical can occur if the braking transistor's duty cycle is too high. Consider installing a regenerative converter. If you have a regenerative converter and the protective function for the braking transistor is enabled, set L8-55 = 0 [Internal DB TransistorProtection Selection = Disable]. If the braking transistor is broken, replace the drive.
Why is there a DC Bus Undervoltage in my YASKAWA Industrial Electrical?
A DC Bus Undervoltage in YASKAWA Industrial Electrical can happen for a few reasons. First, check the input power for any issues causing voltage fluctuations. Also, verify the main circuit drive input power wiring for phase loss. If U4-05 is more than 90%, the main circuit capacitors may be failing, requiring replacement of the control board or the entire drive.
What does Baseblock mean on YASKAWA Controller?
If the YASKAWA Controller indicates a baseblock issue, it means an external baseblock command was entered through one of the MFDI terminals Sx, and the drive output stopped as shown by an external baseblock command. Examine the external sequence and timing of the baseblock command input.
What does External Fault (Terminal Sx) mean on YASKAWA GA50C4004ABA Controller?
If the YASKAWA Controller is showing an External Fault (Terminal Sx), it indicates that MFDI terminal Sx caused an external fault through an external device, or External Fault [H1-xx = 20 to 2B] is set to MFDI terminal, but the terminal is not in use. To fix this: * Remove the cause of the external fault to clear the external fault input in the MFDI. * Correctly set the MFDI.
What to do if YASKAWA GA50C4004ABA Cannot Reset?
If the YASKAWA Controller cannot be reset, it means the drive received a fault reset command when a Run command was active. Turn off the Run command then de-energize and re-energize the drive.
What causes Drive Overload on YASKAWA GA50C4004ABA Controller?
If the YASKAWA Controller indicates a drive overload, consider the following: * The load might be too large: Examine the load. * The drive capacity might be insufficient: Ensure the drive is adequately sized for the load. * The torque might be excessive at low speed: Reduce the load or upgrade to a larger capacity drive, as the drive's overload capability diminishes at lower speeds.
What to do if YASKAWA Controller shows overcurrent?
If the YASKAWA Controller shows an overcurrent error, it could be due to several reasons: * A short circuit in the motor main circuit cable: Replace damaged output or motor cables. * An excessive load: Repair any damaged devices. * An acceleration time that’s too short: Ensure the parameter settings are correct. * Incorrect V/f pattern settings: Verify the parameter settings. * Incorrect motor data: Confirm the sequence of the electromagnetic contactor on the drive output side.
