STEP 4: CONNECT MOTORS
Wire your motors to the included DB9 solder cup and secure the backshell connectors. If your motors are rated below 3.5A you must use a current set resistor across PIN 1 and PIN 5. The resistor is calculated by taking the current in amps and multiplying by 1000. If your motor is rated at 2.8A per phase you will have to use a 2.8K 5% 1/4W resistor. If your motor is rated at 3.5A or above you can safely not use a current set resistor; however, your G540 will not go into current standby mode which will result in increased motor heating.
At this point you should have holding torque on the motors and a green LED lit. If you do not then the motor is wired incorrectly or is damaged.


Are you sure that these were not included in the packet with the back shells and DE9s?
