| SW6 | Half/full current locking |
Phase current is set by “AMPER” knob, and the current value is shown in the table below.
| Dial witches | 0 | 1 | 2 | 3 | 4 | 5 | 5 | 7 |
| Running Current | 0.5A | 1A | 1.5A | 2.0A | 2.5A | 3.0A | 3.5A | 4.0A |
| Dial witches | 8 | 9 | A | B | C | D | E | F |
| Running Current | 4.5A | 5.0A | 5.5A | 6.0A | 6.5A | 7.0A | 7.5A | 8.0A |
Automatic idle current reduction to reduce heat after motor stops moving for 0.1 second if SW6 is set “off”.
Subdivision is set by “STEP” knob, 16 kinds of subdivision are optional.
| Dial witches | 0 | 1 | 2 | 3 | 4 | 5 | 5 | 7 |
| Subdivision(p/rev) | 200 | 400 | 800 | 1600 | 3200 | 6400 | 12800 | 25600 |
| Dial witches | 8 | 9 | A | B | C | D | E | F |
| Subdivision(p/rev) | 1000 | 2000 | 4000 | 5000 | 8000 | 10000 | 2000 | 25000 |
The setting is carried out through SW4=ON. When the self-testing is started, the motor will rotate a circle and then automatically return to the initial position. It can be confirmed whether the driver power works normally and the motor wire connection is reliable.
Note: The external pulse signal will not be accepted under self-test conditions.
The two pulse control input selection is set by SW5.
CW/CCW mode: SW5=ON
PUL/DIR mode: SW5=OFF
