On-Board Temperature Sensor

There is a on-board 1-Wire temperature sensor DS18S20Z+ from Maxim located in the middle of the PCB for optimal readings.
Addional 1-wire sensor(s) can be connected to the connector J16:

Figure 4: 1-wire sensors connector J16.

Power and Power-On Sequence

DC 12V power supply for the Motor and Driver board

The power source must be SELV (Separated or safety extra-low voltageprotected.

The motor drivers and the reference motor on the pre-mounted motor board TEC0060 are supplied by this voltage.

The internal +5V digital supply is generated from this +12V supply.

DC 5...48V power supply for the Motor only


External power supply for the motor must be SELV (Separated or safety extra-low voltageprotected.

Figure 5: The high current parts on the EDPS Board, the motor outputs A, B, C, fuse F1 Connectors J5, J6 and further internal connections, are marked white.

It is mandatory to use the delivered isolating cover of the PCB made of plexiglass as a minimum protection. Use holes H1, H9, H3 and H4 with the delivered 10mm spacers when mounting.

Figure 6: Top view of the EDPS Board with isolating transparent plexiglass cover attached.

Figure 7: Side view of the EDPS Board with isolating plexiglass cover.


The cable lugs used should be isolated in the outer border area of the EDPS Board.

Make sure that the Isolating PCB Cover is overlapping the conducting material by a minimum of 20 mm.

Initial Operation

Prepare the EDPS board as follows:

  1. In the case of low-powered motors and/or low-powered power supply it is recommended to use additional current limiter circuit or additional fuse.
  2. Mount the delivered 30A fuse to the connectors J5 and J6 with the delivered M5 screws.
  3. Use at most 3m long cable with lugs to connect the positive terminal of the motor power supply to J6 (DC +5..48V) and the negative terminal to J1 (0V).
  4. Use at most 3m long cable to connect the three motor phases to J2 (A), J3 (B) and J4 (C).
  5. Connect 12V power supply to J7 (12V). In the case motor power supply voltage is 12V as well, one power supply can be used.
  6. Optional: Connect the encoder to J10 or J11 and set jumper field J13 according to the signal specification either to differential or to single ended configuration.

Power-On Sequence

Any power sequence of the three supply sources is allowed:

Adapter Board TEC0060

For easy connection of the Reference Motor and Encoder to the EDPS Board a special Adapter Board TEC0060 is included in the EDDP Kit.

Figure 8: Adapter Board TEC0060 with the Reference Motor and Plastic DEMO load attached.

Reference Motor

The Reference Motor and Encoder are manufactured by Anaheim Automation. The order code for the motor with the encoder already mounted is BLWR111D-24V-10000-1000SI. Please note that the encoder is not available separately. The nominal motor voltage is DC 24V, however, only 12V is supplied by the Reference Motor Board, which results in reduced performance.

Refer to the BLWR11 - Brushless DC Motors and Single-Ended Encoder with Index Channel for more information.
