Internal HW configuration:
Internal HW configuration describes selectable modifications in hardware. Each item can be present (marked with 1) or absent (marked with 0). A 12-bit binary number is used for this description and is visualized in hexadecimal form. Not all the options are used, these items are marked as "Reserved".
- Powering on method: The device offers several powering methods, defined by
the combination of the following items. For details see powering circuit's detailed specification.
- Internal Fuse
- Flip-flop / One button control
- Constant ON
- Power supply option: Defines isolated supply voltage level on signal connector pin 35.
- CAN terminator: The device has a selectable internal 120-ohm termination resistor. A detailed CAN interface scheme can be found in the CAN communication interface.
- Connected grounds: It is possible to connect two grounding potentials together by the internal jumper.
- ODINs configuration: Defines configuration of pull-up and pull-down resistors for ODINs.
Finish 1 and Finish 2:

- Housing: Defines housing option.
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
