Product User’s Manual – SD02B

d. Please refer to documents named “USB Driver Installation Guide” included in

UC00A package for driver installation.

e. After plugged in UC00A to computer and installed the driver, user is ready to test the

functionality of SD02B using SD02B GUI.

5.5 Enable and Disable the driver

As stated in the Absolute Maximum Rating in chapter 3 (Product Specification and

Limitations), the current consumed may raises up to 2.53A at certain situation. In order to

save power, user is advised to turn off the motor whenever it is possible.

For controlling SD02B using signal input pins, providing a low logic (0V) to EN pin allows

user to “shut off” the driver and get into power saving mode. When stepper motor is idle, it

can be in “stall state” (provide torque and draw current) or “off state” (free, do not draw

current). By default, this pin is disabled.

For controlling SD02B through UART, the ‘OFF’ command will do the same job. Just send

an ‘F’ to SD02B and it will turn off the motor and get into power saving mode. Please refer to

section 7.3, SD02B UART Protocol for details.
