DANGER
⇒ Switch off the control device and the machine and
wait for the discharging time of the electric systems
to elapse.
⇒ 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, fan function and temperature curve
• internal temperature sensor
• motor encoder or encoder connection
• mechanical damage of the motor
• mechanical connection to machine
The encoder connection and the temperature sensor are controlled by the
drive controller or control unit; corresponding diagnoses are indicated.
Observe the notes in the corresponding documentation.
Some sample faults are shown below, along with potential causes. This
