1. SC300 Description
The SC300 motion controller is a new product for controlling orientating position in X,
Y or Z axis. It can also control many types of stepping motors (use corresponding
drivers). It provides the controlling communicating protocol and many commands. It
has characteristics as following:
● Very long distance can be controlled
● The absolute position and the relative position can be displayed
● Stages can be controlled to move forward or backward and to the zero position
● Speed, distance and acceleration can be set arbitrarily
● Position limit switches fitted
Model explanation: SC300-XY

4. Operation Guide
(1) Operating mode introduction
The SC300 has six operating modes which can be changed by MODE and
Number input. The default mode is 1 when power on.
Mode 1 (Absolute position): Displays the absolute position parameters, in unit of step
size. The reference position is mechanical zero.
Mode 2 (Displacement): Displays displacement parameters. Unit is step size.
Mode 3 (Speed): Displays the speed in PPS (pulses/sec).
Mode 4 (Initial speed): Displays the initial speed in PPS.
Mode 5 (Acceleration): Display the acceleration in PPSS (pulses/sec/sec).
Mode 6 (Comparative position): Displays comparative position parameters and the
unit is step size. The reference position is the zero, which is set by user.
(2) Changing the mode: press button MODE continuously, it will range from mode
1 to mode 6.
(3) Setting displacement parameters: set the mode 2 for every axis and input
parameters through Number Input. Then press Enter . Pressing C clears
the last digit number.
(4) Setting top_speed: set the mode 3 for every axis and input parameters through
Number Input. The parameters will be stored in the internal storage, and the
data is not lost when the SC300 is rebooted. Then press Enter . Pressing C
clears the last digit number.
(5) Setting init_speed: set the mode 4 for every axis and input parameters through
Number Input. Then press Enter . The parameters will be stored in the internal
storage, and the data is not lost when the SC300 is rebooted. Pressing C
clears the last digit number.
(6) Setting acc_speed: set the mode 5 for every axis and input parameters through
Number Input. Then press Enter . The parameters will be stored in the internal
storage, and the data is not lost when the SC300 is rebooted. Pressing C
clears the last digit number.

(7) Go back to the mechanical zero position: set the mode 1 for the axis and press
down the Home button.
(8) Go back to the comparative zero position: set the mode 6 for the axis and press
down the Home button.
(9) Setting the comparative zero position (set by user): set the mode 6 for the axis
and press down FWD or BACK .
Press 1 to set the comparative position of axis X to 0.
Press 4 to set the comparative position of axis Y to 0.
Press 7 to set the comparative position of axis Z to 0.
(10) Setting the pulse:
Press the FWD button of X, Y or Z axis and the stage will move forward.
Press the BACK button of X, Y or Z axis and the stage will move backward.
Note: X and Y or X and Z can move at the same time, but Y and Z cannot.
(11) Stop the stage moving: Pressing down the MODE button of X, Y or Z axis
can stop moving in corresponding direction.
Note：
The top_speed, init_speed and acc_speed have the function of protecting power losing.
The three parameters will be stored in the internal storage by SC300 motion controller
after setting them. And these parameters will not lose if you restart the SC300.

7. Formulas Introduction
Total steps per one rotate =360 / step angle
Resolution: The displacement produced with one pulse
Linear stage: Resolution = screw_pitch（mm ）/(total_steps_per_rotation * microstep)
Rotary stage: Resolution=360/((total_steps_per_rotation*microstep*moderate_ratio)
The actual speed of the stage (mm/s)= pulse_speed * resolution
(The pulse speed is the desired speed and its value is from 50 to 20000.)
Transform amount of pulse to angle:
Rotating angle (°) =resolution * amout_of_pulse
Transform angle to amount of pulse:
Amount of pulse = angle/resolution
Transform amount of pulse to displacement:
Displacement (mm) =resolution * amount_of_pulse
Transform displacement to amount of pulse:
Amount of pulse =displacement/resolution
