S2-404Dis an all-digital 2 phase stepper driver. It adopts the advanced controlcalculation, no matter how many steps to set, motor current is the accuratesine. The advantages are excellent performance, super stability, low-speed muteand extremely low heat.
255steps for different transmission ratio
Singlepulse, dual pulse
16kinds of output current
11kinds of lock current percentage (0-100%)
16kinds of lock time (0.1-2 seconds)
ENsignal can work as off-line mode or lock mode
Inputsignal can be any value between 5V and 24V
Automaticallyrecord the breaking point when power off
Greatprotection system (undervoltage, over voltage, over current, etc.)
Wehave been working on drivers over 30 years
Set steps
Steps for the motor rotating one cycle, 255different steps, sw1-4 for steps, 14 steps can directly select, if need othersteps, set sw1-4 to 0000, on=0, off=1

Set current
16 different currents, sw5-8 to set, it’s peak
Sw5-8 | Current | Sw5-8 | Current | Sw5-8 | Current | Sw5-8 | Current |
0000 | 1.2A | 0100 | 2.0A | 1000 | 2.8A | 1100 | 3.6A |
0001 | 1.4A | 0101 | 2.2A | 1001 | 3.0A | 1101 | 3.8A |
0010 | 1.6A | 0110 | 2.4A | 1010 | 3.2A | 1110 | 4.0A |
0011 | 1.8A | 0111 | 2.6A | 1011 | 3.4A | 1111 | 4.2A |
Input signal
3 signals: CP, DIR, EN, signal value 5-24V, singlepulse: CP is pulse signal, one pulse is one step, DIR is direction levelsignal, the signal must be steady before sending CP, dual pulse: CP is positivepulse signal CW, DIR is negative direction pulse signal CCW, EN is enablesignal, when not connect EN, or differential level is 0, then driver is enablestatus, and driver works well, when EN differential level is 1, then driver isnon-enable status, and the driver stopes working, non-enable can set as offlineor lock mode, factory set is offline mode.
Lock current percentage
When the motor does not work, lock current reducesfor less consumption and heat. Different lock percent is available,0%(offline)-10%-20%-30%-40%-50%-60%-70%-80%-90%-100%(full current), default 50%
Lock time
It takes time that pulse signal stops lock currentand make it work, time 0.1s-2.0s, default 1.0s
