If you do not use correct safety equipment, it can cause serious injury or death. image/svg+xml Warning image/svg+xml Electrical Shock Hazard After the drive blows a fuse or trips an ELCB, do not immediately energize the drive or operate peripheral devices. Wait for the time specified on the warning label at a minimum and make sure that all indicators are OFF. Then check the wiring and peripheral device ratings to find the cause of the problem. If you do not know the cause of the problem, contact Yaskawa before you energize the drive or peripheral devices. If you do not fix the problem before you operate the drive or peripheral devices, it can cause serious injury or death. Supply power to the control circuit from the external 24 V input. Use monitor parameters U2-xx [Fault Trace] to show the fault code and data about the operating status of the drive immediately before the fault occurred. Use the information in the Troubleshooting tables to remove the fault. Note: To find the faults that were triggered, check the fault history in U2-02 [Previous Fault]. To find information about drive status (such as frequency, current, and voltage) when the faults were triggered, check U2-03 to U2-20. If the fault display stays after you re-energize the drive, remove the cause of the fault and reset.
