IndraDyn A motors are equipped with two PTC temperature sensors
KTY84-130 which are mounted stationary into the motor winding. For
additional information on temperature sensors refer to Chapter 9.9 "Motor
Temperature Overview".
Note:
• For the connection diagram, see Fig. 8-3 and Fig. 8-6 at
the beginning of this chapter.
• Notice the correct polarity when using the sensor for
temperature measurement external (see Fig. 9-18).
• The signal lines to the PTC sensors are routed to the
controller via the motor power cable.
• Only one sensor is connected and evaluated. The function
of the spare sensor cannot be guaranteed.
The motor holding brake is triggered either directly through the drive
device, or externally.
Note:
• For the connection diagram, see Fig. 8-3 and Fig. 8-6 at
the beginning of this chapter.
• Control voltage is +24 V
• Take note of the different functions of an electrically
clamping and an electrically releasing brake (see chapter
9.10, "Motor Holding Brake").
The motor fan is connected to the supply system via a cable and motor
protecting switch and functions independent of the drive device.
