42 57 stepper motor driver CW angle CCW pulse speed drive module device board DC8V ~ 24V 1. Two modes: Jog turns on when signal is given, stop when signal disappears. Self-locking engages when a signal is given and stops when the signal is given again2. Angle setting: give CW signal, CW stop distance; Signal CCW; CCW B stop distance, CW and CCW angles can be set to different3. Auto guidance: it automatically stops when the signal is rotated to distance, after C time delay, it will automatically return and stop automatically when CW is rotated to distance again, and the same applies to CCW4 infinite loop. Cycle process: after power on, it will automatically rotate CW to distance A, stop for C seconds, then CCW to distance B and stop for C seconds, infinite loop5. Stable and durable: stepper motor driver have stable structure, excellent performance and long service life Specification: Item type: 42 57 stepper motor driver Material: ABS Color: black and blue Power range: DC 8V ~ 24V universal Speed range: 0.1 ~ 999 minutes (with its own power off function )Positive and negative pulse range: 10 ~ 99990 pulses Adjustable delay time range: 0.1 seconds to 999 seconds Function selection setting range: P-1 ~ P-6 Sub-area selection setting range: 1 ~ 128 sub-areas Package list: 1 x 42 57 stepper motor driver
