Operating IndraDyn A Motors Rexroth IndraDyn A
Note:
The option of automatically implementing the burn-in routine in
the program run is described in the documentation of the
particular drive controllers.
During normal operation, it is not necessary to burn-in the brake.
It is sufficient if the brake is activated twice a day by removing the
controller enable signal.
12.5 Troubleshooting
DANGER
Danger of injury due to moving elements!
Danger of injury due to hot surfaces!
⇒
Do not carry out any maintenance measures when
the machine is running.
⇒
Switch off the control-device and the machine and
await the discharging time of the electric systems
⇒
During maintenance work, secure the system against
restarting and unauthorized use.
⇒
Do not work on hot surfaces.
Possible causes for the malfunctioning of IndraDyn A motors can be
limited to the following areas:
•
Motor-cooling circuit, or blower function temperature curve
•
Internal temperature sensor
•
Motor encoder or encoder connection
•
Mechanical damage of the motor
•
Mechanical connection to machine
Encoder connection and temperature sensor are controlled by the drive-
controller or control unit, and corresponding diagnoses are indicated.
Observe the notes in the corresponding documentation.
Subsequently some troubles are shown exemplary with potential reasons.
This list does not lay claim to completeness.
Excess Temperature of Motor Housing
The housing temperature of the motor climbs to unusually high values.
CAUTION
Damage of motor or machine by restart after
raised motor temperature!
⇒
Liquid cooled motors should not be reloaded
immediately or with cold coolant after loss of the
coolant system. Danger of damage!
⇒
Wait before you re-start until the motor temperature
has dropped to 40°C.
