normal mode; the DOG falling-edge detection in zero return mode is
On.
Zero return mode: The motor runs at the zero return speed V
RT
, and when it
reaches a DOG signal, the motor will decelerate to the zero return deceleration
speed V
CR.
After it further detects a falling edge of a DOG signal, the motor will
output N pulses and P pulses before it stops.
y
If N and P are too small, the motor will decelerate to V
CR
when reaching a DOG
signal. After the motor detects a DOG falling edge and if N is reached, the motor
will stop immediately after P is reached even if the motor has not reached V
CR
.
y
Assume N and P are set to “0”, the motor will stop immediately after it reaches a
DOG signal and detects a DOG falling edge.
