Resetting faults
DOK-INDRV*-HMV-*******-PR01-EN-P
Extensive searches for faults and repair of drive components on the
machine are not acceptable due to the production downtime involved.
The modular concept of Rexroth drives makes it possible to completely
exchange drive components. Service thus means localizing problems
either on the motor, drive controller or power supply unit and replacing the
part.
Hinweis: No further adjustments are needed.
The supply unit signals operating states, warnings or faults via a display.
A prerequisite for fault diagnoses is control voltages and processors in the
supply units and drive controllers that are working properly.
Stored fault messages must be reset before the unit will again operate.
An error can be reset by
• pressing key "Esc" on the control panel (display),
• switching the control voltage off or
• generating the reset command of the drive controller via the bus
module.
Destruction of the power supply module, if the
power is switched on to a faulty drive
controller!
⇒ Upon RESET of an over current fault and after
CAUTION
replacement of a defective supply module, the fault
memories of the drive controllers must be read out
prior to switching it on.
If either checks or repairs are needed, then it applies:
• Checks and repairs may only be conducted by Rexroth customer
service personnel or such personnel that has been trained to do so.
• Observe the applicable safety regulations when checking the unit.
• Repairing drive components on the machine is very time consuming.
Replace defective drive components completely.
When faults are cleared, damages to the
machine and injury to the personnel may occur!
⇒ Fault clearance should only be conducted by trained
personnel.
WARNING
⇒ Protective devices must not be switched off.
⇒ Note the warnings in chapter 3.
