Typical wiring diagram

warning

Incorrect wiring – risk of malfunction/damage to equipment

This section provides a typical wiring diagram. The integrator can modify the configuration of the diagram according to their needs and requirements. Creating the wiring diagram for the end application is the responsibility of the integrator.

Below is the typical scheme for the standard variant of the TX controller (12dxa1020-800_00000-000BB), together with the description of the main components.

Main DC fuse

Installing a fuse on the main battery lead is recommended to ensure protection in case of a short circuit on the power circuit. The fuse is typically connected between the battery + terminal and the + lead on the controller side.

The selection of a suitable fuse is the integrator's responsibility. It is recommended that the short-circuit fuse ideally blows within approximately 2 - 3 seconds when the DC current passing through it reaches twice the DC current value for peak power at the specified voltage of the end application.

Main switch

The controller's logic circuit is powered through the KEY pin. In this case, the KEY pin is connected to the battery + through the internal fuse.

The controller is turned ON once the main switch is turned to the "Closed" position (Key and Power connected together) and turned OFF if turned to the "Open" position (Key and Power disconnected). This is usually done by a SPST switch.

info

The total length of the wires to the main switch should be shorter than 10m.

Motor

info

A motor with permanent magnets induces voltage (back-EMF) while spinning. This voltage is directly proportional to the motor's revolutions per minute (rpm). When the motor operates beyond its nominal rpm, it is crucial to ensure that the amplitude of the back EMF remains below the non-operational overvoltage limit.

warning

High voltage – risk of personnel injury and/or damage to equipment

In this particular case, the motor is equipped with 3 hall sensors together with the motor winding temperature sensor. The used controller is in the motor sensor variant - 'a'. More technical details can be found in Motor position sensor and Motor temperature sensor chapters.

Throttle

The controller can process a wide range of analog throttles which provide output signal in the range of 0 - 5 V. It can be a potentiometer, hall type or just an analog signal provided by a voltage source.

The controller has also a dedicated +5 V power supply for the throttle. Detailed technical specifications can be found in this chapter.

CAN interface

The controller can be a part of the CAN system. CAN interface can be used for commanding the controller or for data exchange between the nodes.

Detailed technical specifications of the CAN interface can be found in this chapter.
