In the last issue, we talked about the wiring among stepping motor, stepping driver and PLC. In this issue, we continue to explain the setting of stepping driver.
Generally, we have two parameters to set for stepping driver, one is Subdivision and the other is current.
The current only needs to be set to the rated current of the stepping motor.
Directly through the dip switch S4, S5, S6 according to the current parameter setting table above the driver to set. For example, the rated current of stepping motor is 3.
5A, then dial S4, S5 and S6 all OFF.
In fact, the subdivision can be simply understood as how many pulse motors rotate one turn.
For example, when my lead screw rotates once, the slider moves 8mm, that is, the lead = 8mm.
At this time, if I want plc to send a pulse slider to move 0. 01mm.
Then I can set the subdivision to 800, that is, the fourth gear subdivision. If the inherent step angle of the motor is 1. 8 °
, The step angle = Motor inherent step angle/subdivision = 1. 8 °/4 = 0. 45 °
, S1, S2, and S3 are switched to ON, OFF, and OFF, respectively.
At this point, our stepper drive is set up.
