Overview

Refer to https://wiki.trenz-electronic.de/display/PD/EDPS+User+Manual for online version of this manual and additional technical documentation of the product.

The Trenz Electronic TEC0053 is a Motor Driver board to be used together with the reference controller board for motor control evaluation.

Key Features

• Evaluation of the Motor control with the suitable controller board 
• Power option up to 48V and 30A main supply current
• MOSFET power stage supporting 3-phase BLDC motors
• Current measurement on 2-phases (3 phase measurement is optional)
• On-board temperature sensor and 1-wire bus connector for additional sensors
• Encoder input capable of receiving both single ended and differential signals

General Safety Instructions

• This product should be operated only by qualified electrical specialist.
• Never leave operating board unattended.
• There is a possible risk of burns due to the hot surfaces while operating the Board. Reason for this could be the high currents present in the motor driving outputs.
  
• All externally connected power sources must be SELV protected (Separated or Safety Extra Low Voltage).
• All wiring and installation should be performed only with all external power sources switched OFF or disconnected.
  
• No wiring or mechanical setup changes should be performed while the board is operating.
  
• The product is rated for indoor, dry environment use only.
  
• The product is intended to be used only in horizontal position on a non-conducting and non-inflammable surface.
• The mechanical setup must ensure that the board and all of its parts are firmly fixed in place to prevent accidental or unwanted movement(e.g. sliding, falling. etc.).

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:

...

• 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

DC 12V power supply for the Motor and Driver board

The power source must be SELV (Separated or safety extra-low voltage) protected.

...

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

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

SAFETY INSTRUCTIONS:

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

...

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

Initial Operation

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 of the used motor a fuse with a suitable lower current rating integrated in the supply wiring is recommended.
3. Connect with cable lugs the DC of +5..48V to J6 and the corresponding GND to J1.
   1. The cable length is limited to 3m.
4. Connect the three motor phases to J2 (A), J3 (B) and J4 (C).
   1. The cable length is limited to 3m.
5. Optional: Connect the encoder to J10 or J11 and set jumper field according to signal specification (differential or single ended).

Power-On Sequence

Any power sequence of the three supply sources is allowed:

• +3V3 Supply from the Control Board, generated by Control 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.

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