U2-202D   is an all~digital 2 phase stepper driver. It adopts the advanced control calculation, no matter how many steps to set, motor current is the accurate sine. The advantages are excellent performance, super stability, low-speed mute and extremely low heat.

255 steps for different transmission ratio

Single pulse, dual pulse

16 kinds of output current

11 kinds of lock current percentage (0-100%)

16 kinds of lock time (0.1-2 seconds)

EN signal can work as off-line mode or lock mode

Input signal can be any value between 5V and 24V

Automatically record the breaking point when power off

Great protection system (undervoltage, over voltage, over current, etc.)

We have been working on drivers over 30 years

Set current

16 differentcurrents, sw5-8 to set, it’s peak

Set steps

Steps for the motor rotating onecycle, 255 different steps, sw1-4 for steps, 14 steps can directly select, ifneed other steps, set sw1-4 to 0000, on=0, off=1

Inputsignal

3signals: CP, DIR, EN, signal value 5~24V, single pulse: CP is pulse signal, onepulse is one step, DIR is direction level signal, the signal must be steadybefore sending CP, dual pulse: CP is positive pulse signal CW, DIR is negativedirection pulse signal CCW, EN is enable signal, when not connect EN, ordifferential level is 0, then driver is enable status, and driver works well,when EN differential level is 1, then driver is non-enable status, and thedriver stopes working, non-enable can set as offline or lock mode, factory setis offline mode.

Lock current percentage

When the motor does notwork, lock current reduces for less consumption and heat. Different lockpercent is available, 0%(offline)-10%-20%-30%-40%-50%-60%-70%-80%-90%-100%(fullcurrent), default 50%

Lock time

It takes time that pulsesignal stops lock current and make it work, time 0.1s-2.0s, default 1.0s

Indicator light status
