To Next PageTo Next PageWhat to do if YASKAWA DC Drives have an Output Phase Loss?
If YASKAWA DC Drives report an output phase loss, it could be due to: * A disconnected output cable or damaged motor winding. * Loose wires at the drive output. * A motor that is too small (less than 5% of drive current). To resolve this, check the motor wiring, ensure all terminal screws in the drive and motor are properly tightened, and verify the motor and drive capacity.
What does 'Drive Disable' mean on YASKAWA DC Drives?
If YASKAWA DC Drives show 'Drive Disable', it means both Drive Disable inputs are open, which safely disables the drive output, preventing the motor from starting. This could be because the upper controller's safety device disabled the drive. To fix this, determine why the upper controller disabled the drive, remove the cause, and restart. Also, check the wiring. If the Drive Disable function is not used for EN60204-1, terminals HC, H1, and H2 must be linked.
What causes an Input Phase Loss in YASKAWA DC Drives?
An input phase loss in YASKAWA DC Drives can be caused by: * Input voltage drop or phase imbalance. * One of the input phases being lost. * Loose wires at the drive input. To resolve this, check the power supply and ensure that all cables are properly fixed to the correct terminals.
