3.4.2  Stepper motor connection 

General information 

The motor is connected to the SMCI36 with a 4-wire cable. Twisted wire pair cables 
with braided shields are recommended. 

 

 

Danger of electrical overvoltage 

Accidentally swapping the connections will destroy the output stage. See the data 
sheet of the connected stepper motor. 
Never disconnect the motor while operating voltage is applied! 

Never

 hot-unplug lines. 

3.4.3  BLDC motor connection 

See Section BLDC motor “2.3”.
