Table 2: Description of the Motor and Power connector.
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.
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.
External power supply for the motor must be SELV (Separated or safety extra-low voltage) protected.
only allowed to be used, if the high current parts conducting up to 30A nominal, are covered by isolating, mechanically stable, non-inflammable (UL V-1 or better) material. The high current parts are shown on the following picture:
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.
Prepare the EDPS board as follows:
Any power sequence of the three supply sources is allowed:
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.
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.
