Rexroth IndraDyn A Operating IndraDyn A Motors
12-7
1. Failure or malfunction in the blower or cooling system.
2. Original processing cycle has been changed.
3. Original motor parameters have been changed.
4. Motor bearings are worn or defective.
1. With
MAD,
check blower function. Clean if necessary.
In the case of failure, contact Bosch Rexroth Service.
With
MAF,
check the cooling system. Clean or rinse the cooling
circuit as needed. Contact the machine manufacturer upon failure of
the coolant system.
2. Check the layout of the drive for changed requirements. If overloading
occurs, stop operation. Danger of damage!
3. Reset to the original parameters. Check the dimensioning of the drive
in the case of changed requirements.
4. Contact the machine manufacturer.
High motor temperature values, but housing temperature is normal
The diagnostics system of the drive controller shows unusually high
values for the winding temperature via the display or control software.
However, the motor housing has a normal temperature.
1. Wiring error or cable break in sensor cable.
2. Diagnostics system defective.
3. Winding temperature sensor failure (PTC).
1. Check the wiring and connection of the temperature sensor according
to the connection plan.
2. Check the diagnostics system on the device controller or the control.
3. Check the resistance value of the temperature sensor using a
multimeter.
•
Set the measuring instrument to resistance measurement.
•
Switch off the system and await the discharging time. Separate the
temperature sensor connection from the device controller and
connect the wire pair with the measuring instrument (this includes
the sensor cable in the test). Check the values according to the
characteristic curve in Fig. 9-16
Motor or Rotary Table Generates Vibrations
Audible or tactile vibrations occur on the motor.
1. Driven machine elements are insufficiently coupled or damaged.
2. Motor bearings worn or defective. Available bearing life time or
grease life time elapsed.
3. Motor mount loose.
4. Drive system control loop is instable from a control point of view.
1. Contact the machine manufacturer.
2. Contact the machine manufacturer.
3. Check the mechanical connection. Do not continue to use damaged
parts. Contact the machine manufacturer.
