Onboard is a Maxim 1-Wire Temperature sensor DS18S20Z+. This sensor is located at in the middle of the PCB.
Addional 1-Wire temperature sensor(s) can be connected by wires to the connector J16:
- Pin 1(DQ), 3 (GND),5 (+3.3V) at the same 1-wire bus as the onboard one
- Pin 2(DQ), 4 (GND),6 (+3.3V) at a separate 1-wire bus

DC 12V Supply Motor and Driver
This externally The power supply sources source must be SELV protected (Separated or safety extra-low voltage) protected.
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 out of from this +12V supply.
DC 5...48V Supply for Motor only
...
Externally power supply for the motor must be SELV protected (Separated or safety extra-low voltage) protected.
This option is
- only allowed to be used for electrical specialist for the used electrical voltage and power conditions
- only allowed to be used under electrical laboratory conditions
- only allowed to be used in horizontal position on a non-conducting and non-inflammable surface
- only allowed to be used with a wiring, which fulfills the current rating for the maximum possible currents.
- only allowed to be used with a suitable current limiting circuit
- The maximum continuous current must not exceed 30A.
- The delivered fuse "Littelfuse Tpye 142.5631.5302" must be used as current limiter between connector J5 and J6.
- To limit the current for smaller motor loads an ADDITIONALLY appropriate current limiter can be used e.g. a current limited power source or a fuse integrated in the wiring.
- only allowed to be used with appropriate connectors at the M5 screw connectors, which means M5 cable lugs must be used and fastened according to technical standards.
- only allowed to be used, if the "Eval Boad high current signals" conducting up to 30A nominal, are covered by isolating, mechanically stable, non-inflammable (UL V-1 or better) material
The "Eval Boad high current signals" are the motor outputs A, B, C and Fuse F1 Connectors J5 an J6 and further internal connections shown white marked in the following picture:
- As minimum protection it is mandatory to use the delivered "Isolating cover PCB" (marked in green), which must be mounted to the mounting holes H1, H9, H3, H4 with the delivered 10mm isolating spacers:
- The used cable lugs need to be isolated in the area outstanding the outer border of the Eval Board.
Intention is to make Make sure that the "Isolating Cover PCB" is overlapping the conducting material by a minimum of 2 cm20 mm.
Initial operation
The option 2 motor supply is only usable after To use a separate power supply for the motor supply perform the following steps are done:
- Disconnecting Disconnect the reference motor board TEC0060 by unmounting its screws and the encoder cable from J10
- Mounting Mount the delivered 30A Fuse fuse to the connectors J5 and J6 with the delivered M5 screws
- For lower supply current requirements, caused by the power rating of the used motor, a fuse with a lower and suitable current rating integrated in the supply wiring is recommended.
- Connecting Connect with a cable lugs the +DC 5..48V to J6 and the corresponding GND to J1.
- The cable length is limited to 3m.
- Connection Connect the three motor phases to J2 (A), J3 (B) and J4 (C).
- The cable length is limited to 3m.
- Optional: connect the encoder wires to J10 or J11
and set jumper field according to signal specification: differential or single ended
. See section TODO for details.

For easy connection of the reference Motor and Encoder to the Driver board a special Motor Adapter Board TEC0060 is included in the EDDP Kit.
Reference Motor
The manufaturer of the reference motor is manufactured by Anaheim Automation and the . The order code of the delivered combination of for the motor with the encoder already mounted is BLWR111D-24V-10000-1000SI. Please note that the encoder is not available separatly, they are premounted to the motor at the manufacturer.
separately. The nominal motor voltage is DC 24V which , however, only 12V is supplied by DC 12V on the Reference Motor Board. This will cause a certain derating in performace, which results in reduced performance.
