LED status indicator

The LED status indicator informs about the current state of the motor controller according to table below.

LED state	Controller condition
Permanently turned OFF	Controller is not powered up
Briefly turned ON and after a few sec OFF	Controller is powered and fully functional
Permanently turned ON	Controller indicates that any of the protections are active. Output current can be limited.
Blinking	Controller indicates an internal error and is blinking a 16-bit error code. Controller's power stage is deactivated

Accessories

Signal connector

• mating housing: Molex 5016463600
• crimp terminals: Molex 5016471000
• crimp tool: Molex 638192300

Signal connector sealing

The controller's signal connector sealing is designed as a separate part to keep the controller dimensions as small as possible. It is installed on the signal connector cables (see drawing). This part is the same for the AX and for the TX controller.

The product number for purchasing: AX_signal_sealing.

The controller fulfills the environmental specification only if this sealing is properly installed.

AX Molex holder

This tool helps you to assemble an TX (or AX) connector with the sealing. The AX Molex holder holds the Molex connector with the sealing, so you can easily insert wires with crimp.

You can download the model here: AX Molex holder and 3D print the holder.

Pre-crimped wires

siliXcon can provide pre-crimped wires for end-application prototyping. The bare wires with iGrid crimp on one end can be purchased by following ordering codes:

Part name	description	wire color
Cable_i-grid_black_50	Black cable, 0,25mm2, 50cm length	Black
Cable_i-grid_red_50	Red cable, 0,25mm2, 50cm length	Red
Cable_i-grid_white_50	White cable, 0,25mm2, 50cm length	White
Cable_i-grid_green_50	Green cable, 0,25mm2, 50cm length	Green
Cable_i-grid_blue_50	Blue cable, 0,25mm2, 50cm length	Blue
Cable_i-grid_yellow_50	Yellow cable, 0,25mm2, 50cm length	Yellow

Power connectors

• mating connector: M5 cable lug up to 25 mm2 + M5 screw. Terminal thread length is 10 mm, maximum tightening torque is 5 Nm. Cable lug example: JST GS5-25. Check the clearance between mounted cable lugs. Tighten the lugs properly and secure the wires against movement (lug rotation) to prevent shortcut.

Mounting screws

• 4x M4 or M5 screw. M4 screws are through the heatsink, M5 screws have a thread in the heatsink. Refer to the TX controller drawing.
• for through-hole mounting, minimum thread depth is 1.5 x screw diameter. Tightening torque depends on the material of the mounting base.

Thermal grease

• to improve cooling of the controller, you should apply thermal grease to the mounting area of the controller. Example: Electrolube HTC, AG termopasty HPX
