※ PA-common parameters list:
No. Name Function Default
Range
PA-2
Operation mode
selection
0: Self-running (Triggered by
pulse signal. When the pulse
signal is turned on, the motor
starts to run according to the
parameter settings of PA-45 ~
PA-53; when it is off, the motor
stops running)
2 0~3
1: Open loop mode (run
without encoder line)
2: Servo mode 0
3: Servo mode 1
PA-4
Positional accuracy

1~65535
encoder
pulses
PA-6
Electronic gear ratio
numerator
4000 1~65535
PA-7
Electronic gear ratio
denominator (pulse
per round)
When PA-6 is set to 4000,
PA-7 value is equivalent to the
number of pulses required for
one round of the stepper motor
(microstep).
1600 1~60000

function setting
1 MF is used as a general
motor release signal
0 MF as a pulse blocking
function
1 0/1
