MAINTENANCE & TROUBLESHOOTINGDrive MaintenanceRoutine maintenance is not necessary, but occasional checking of the following points isrecommended.Motor MaintenancePeriodically check the motor to ensure that no bolts or couplings have become loose duringoperation, and check the motor cable or leads periodically for signs of wear. Do not make verytight bends or pull on the cable during normal operation. Check all cable connectors and thesafety earth connection.Drive MaintenanceCheck that the drive is clear of loose material and has a free flow of air through the ventilationslots. Check all drive connector jacking screws are firmly tightened and the motor screenconnection is secure.FusesBDE drives are fitted with fuses which limit circuit damage in the event of a fault occurring, theyare not user replaceable. If the drive fails to operate correctly or you suspect a fuse has blownreturn the drive for repair. Warranty is void if the case is opened.TroubleshootingDrive or system problems may be indicated by one of the front panel LEDs lighting up whilst thedrive is operating.Note: The central 'HV Present' LED will always be alight whilst the DC bus voltage is present.This does not necessarily mean that the internal logic supplies are present. The LED will remainalight even when mains power is removed, as the high voltage capacitors will still be charged.WARNING - Danger of electric shockLethal voltages are present on the mains input connector and the motor phase outputs.After removing AC power, wait for the 'HV Present' LED to go out before touching the driveterminals. Do not remove the drive cover, there are no user-serviceable parts inside.Removal of the cover voids the warranty and EMC compliance.
