The setting of current,microstepping and current-decay mode adjustable
|
|
6.1、 Current-decay mode setting:
Board marked D1D2 (match with DIP swtich 1 and 2) to set the value of switching current-decay
D1/D2： ON/ON——100%； ON/OF——25%；
OF/ON——50%； OF/OF——0%；
| D1 | D2 | Working mode |
| ON | ON | Fast decay |
| OF | ON | 50% of fast decay |
| ON | OF | 25%of fast decay |
| OFF | OFF | Slow decay |
Microstepping setting
Board marked M1M2(match with DIP swtich 3 and 4) to set the value of switching microstepping resolution
| M1 | M2 | Working mode |
| OFF | ON | 1/16 |
| OFF | OFF | 1/4 |
| ON | OFF | 1/2 |
| ON | ON |
Remark: For motor run smoothly, please try to select high segments, such as 1 / 16 microstepping
6.3、 current setting:
Board marked T1T2(match with DIP swtich 1 and 2) to set the value of switching current setting
| T1 | T2 | Current |
| OFF | ON | 25%*2.5A |
| ON | ON | 50%*2.5A |
| ON | OFF | 75%*2.5A |
| OFF | OFF | 100%*2.5A |
Proposed current as close as possible stepper motor rated current
