View or change the Miscellaneous settings described below. Options vary with amplifier
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.
