Basic wiring scheme

SimuCUBE basic wiring scheme. Please see the motor position sensor table for the DB15 connector pinout.

RJ45 connector wiring examples

Example of how to wire buttons and analog signals to SimuCUBE.
Easiest way to wire the rj45 connectors are through a terminal block adapter such as this. Items like this can be obtained for example from eBay (try this search).

Internal connector pinouts

EXT-LEDS connector is directly wired to microcontroller I/O pins without any protection devices (such as ESD clamp diodes, or resistors). Any miswiring may cause permanent damage to the drive.
Damage caused through EXT-LEDS connector is not covered by the warranty.
SimuCUBE internal connectors.

External resistor connection

For SimuCUBE Hardware Revision 2 (1r005 printed on the PCB), it is possible to use an external regenerative braking resistor. Suitable external resistor should have resistance of 2.5 Ohm and rated power of at least 25 Watts. We recommend 50 Watts.

Please note, that if, for whatever reason, the internal resistor on the SimuCUBE has cracked, the steps listed SimuCUBE troubleshooting should be performed to analyze the health of the MOSFET transistor.

Internal/External resistor in use Pins connected in the screw terminal on Pinout 6 in the above image Default from factory
Internal Resistor Input and Internal Resistor connected via a jumper block Default
External Remove jumper and connect external resistor between Resistor Input and HV BUS Output
