6. Guidelines on fault clearance

6. Troubleshooting guidelines

Lengthy troubleshooting and repair to drive components on the machine are

not acceptable because of the resulting production down-time.

Thanks to their construction, INDRAMAT AC drives enable individual functional

units to be easily and completely replaced without the need for tuning.

This means servicing is limited to fault-location either in the motor, the power

supply module or the drive in the event of a fault. The faulty component can

also simply be exchanged.

6.1. Troubleshooting

Because of the interaction between the NC control unit, the supply and drive

modules, the motor, the mechanical system and position measurement, poor

performance of axis movements can be caused by a fault in the above devices

or incorrect interfacing of individual components. The KDV 2.3 has a

comprehensive diagnostic system for rapid fault location.

A fault increases the risk of an accident. Personnel, machinery and drives are

at risk.

Troubleshooting and equipment repair must only be performed by

trained personnel! This personnel must be able to recognize the

dangers of electrical or mechanical equipment, and prevent

dangerous situations!

Personnel is not permitted in the danger zone.

Safety measures such as safety screens, covers, and light barriers

must be present.

Access to the E-Stop button must be free and ready.

The following applies when working within the danger zone:

The power to the installation must be switched off and the system

locked so that it cannot be switched back on when working within

the danger zone.

Wait until the DC bus has completely discharged. Depending upon

the DC bus capacitors used, discharge time can take several

minutes. Verify voltage by measuring at X9 (L+/L-).
