model. 
Setting Description 
Commutation  Select commutation method: Sinusoidal or Trapezoidal. 
Use back EMF 
for Velocity 
If selected, will use the motor’s measured back EMF to determine 
motor velocity. Recommended only for medium- to high-speed. 
Accuracy depends on the accuracy of the programmed Back EMF 
value, and may be affected by factors such as cable resistance. 
Use Halls for 
Velocity and 
Position 
If selected, will use transitions of the Hall switches to determine 
motor velocity and position. Recommended only for medium- to 
high-speed applications (may run roughly at low speeds). 
Multi-mode 
Port 
Selects the mode for the amplifier’s multi-mode port: 
• Buffered Motor Encoder. The multi-mode port functions as a buffered 
digital encoder output based on the digital encoder input. 
• Emulated Motor Encoder. The multi-mode port functions as an emulated 
digital encoder output based on the motor analog encoder or motor 
resolver. 
• Emulated Position Encoder. The multi-mode port functions as an 
emulated digital encoder output based on the position analog encoder. 
• Differential Input. The multi-mode port functions as a differential 
command input.
