10. Servicing notes
10.1. Fault diagnosis
10. Servicing guidelines
The TDA 1 diagnoses drive faults via the display on the control panel.
Should a fault occur, the drive will brake to a standstill, and the drive
package will then cut the power. Fault diagnoses are the same for all
different types of mains spindle controllers.
Therefore, the fault diagnoses and instructions on how to clear faults are
described in the documentation "AC main spindle drives with controlled
asynchronous motors or frameless spindle motors; Applications Manual"
(No. 209-0041-4109), which is valid for all INDRAMAT main spindle
drives.
In order to guarantee a high degree of machine up-time, a defective TDA
1 will be replaced, the defective unit being sent back to INDRAMAT for
repair.
Since the TDA 1 has been matched to the drive and the machine via the
programming module AS, this programming module is transferred to the
new unit replacing the old one. The drive equipped with a new TDA 1 now
displays the same characteristics as the original drive.
If it becomes necessary to replace a unit, the procedure is as follows:
– Prior to any work on electrical equipment, open the master switch and
secure it against reconnection. The drives must be at a standstill,
otherwise voltage will appear on the motor cables when the motors
rotate.
– Wait for the link circuit (L+, L-) to discharge (>= 1 min), and check that
the voltage level is under 50 V before beginning to work. If in doubt,
short-circuit (Cu-conductor, A >= 6mm
2 )!
– Unscrew the protective cover (transparent plate) of the TDA 1 and the
adjacent units in the drive package.
– Remove the rails of the link circuit bus and disengage all other
connections.
– Loosen the Allen screws at the top and bottom of the housing and
remove the TDA 1 from the drive package.
When mounting the new TDA 1, grip it at the top and bottom
faces of the housing, otherwise you may risk injuring a hand.
– Hang the new TDA 1 on the screws and tighten them down.
