Internal
Temperature Sensor
Onboard is a Maxim 1-Wire Temperature sensor DS18S20Z+. This sensor is located in the middle of the PCB.
Addional 1-Wire temperature sensor(s) can be connected 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
Power and Power-On Sequence
Power Supply
DC 12V Supply Motor and Driver
The power source must be SELV (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 from this +12V supply.
DC 5...48V Supply for Motor only
SAFETY INSTRUCTIONS:
Externally power supply for the motor must be SELV (Separated or safety extra-low voltage) protected.
This option is
...
- 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.

Initial operation
To use a separate power supply for the motor supply perform the following steps:
- Disconnect the reference motor board TEC0060 by unmounting its screws and the encoder cable from J10
- Mount the delivered 30A 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.
- Connect with cable lugs the +DC 5..48V to J6 and the corresponding GND to J1.
- The cable length is limited to 3m.
- Connect the three motor phases to J2 (A), J3 (B) and J4 (C).
- The cable length is limited to 3m.
- Optional: connect the encoder to J10 or J11 and set jumper field according to signal specification: differential or single ended. See section TODO for details.
Power Consumption

Test Condition:
- 25 °C ambient
- Reference motor running with no load
...
Power-On Sequence
Any power sequence of the three supply sources is allowed:
- +3V3 Supply from the FPGA Board, generated by FPGA Board supply
- +12V and
- optional +5..48V Motor Supply
Reference Motor Board TEC0060
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 reference motor is 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.
The datasheet for the motor can be found at
