General Safety Instructions

• This product is only allowed to be used by an should be operated by qualified electrical specialist only.
• This product is not allowed to be used Never leave an operating board unattended.

• All externally connected power sources must be SELV protected (Separated or safety extra-low voltageSafety Extra Low Voltage).
• For set up the wiring switch off or disconnect All wiring and installation should be performed only with all external power suppliessources switched OFF or disconnected.
  
• During operations it is not allowed to change the No wiring or mechanical setup changes should be performed while the board is operating.
  
• This The product is only allowed to be used in a rated for dry indoor environment use only.
  
• The product is only allowed intended to be used only in horizontal position on a non-conducting and non-inflammable surface.
• The mechanical setup must ensure that the whole test setup can not be dropped to the floor or moved accidentally.

SAFETY INSTRUCTIONS:

Externally External power supply for the motor must be SELV (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 such that the maximum continuous current must does not exceed 30A as follows:
  .
  • The delivered fuse "Littelfuse Tpye Type 142.5631.5302" must be used as current limiter between connector connectors J5 and J6.
  • To limit the current for smaller motor loads an ADDITIONALLY ADDITIONALL 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

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.

To use a separate power supply for the motor supply perform the following steps:

1. Disconnect the reference motor board TEC0060 by unmounting its screws and the encoder cable from J10
2. Mount the delivered 30A fuse to the connectors J5 and J6 with the delivered M5 screws
   1. 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.
3. Connect with cable lugs the +DC 5..48V to J6 and the corresponding GND to J1.
   1. The cable length is limited to 3m.
4. .
5. 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).
6. Use at most 3m long cable to connect Connect the three motor phases to J2 (A), J3 (B) and J4 (C).The cable length is limited to 3m
7. Connect 12V power supply to J7 (12V). In the case motor power supply voltage is 12V as well, one power supply can be used.
8. Optional: connect 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. See section TODO for details.

Reference Motor

The reference motor is 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.

The datasheet for the motor can be found at
