Micro Step (SW1-SW4)
Each CL42T(V4.1) has 16 microstep settings which can be configured through DIP switches SW1, SW2, SW3
and SW4.See the following table for detail.

Rotation Direction CW (clockwise) CCW (counterclockwise)
SW6
Control Mode Open loop control Closed loop control
SW7
Pulse Mode CW/CCW (double pulse)
PUL/DIR (single pulse)
SW8
Pulse Filter Time Yes (10ms) No (1.5ms)
CL42T(V4.1) has an advanced feature called Pulse Filter Time to make the input pulse from pulse generator
(controller,PLC, etc.) S-curve acceleration, to improve motion smoothness and high-speed start frequency in
manycircumstances.
The Filter Time value must be set to the same for each CL42T(V4.1) in multi-axis applications
5.3
S3 - Selector Switch Configurations
The 1-bit selector is located on the top (S3 in figure 2), used to configure the voltage of control signals. For the
safety of optically coupled, the factory setting is 24V, which no need to connect 2K resistors, making it easier to
use. Whenthe voltage of the control signal is 5V, the S3 must be set to 5V, otherwise, the motor won't work.
