Introduction:
3MD560 is a new 3 phase high resolution stepping driver employed precision current control technology. It is suitable for driving NEMA 17, NEMA 23 and NEMA 34 3-phase hybrid stepping motors. By employing the advanced pure-sinusoidal current control technology, both the noise and the vibration of the motor have been greatly reduced, which makes the performance of stepping motors approach to those of servo motors. Furthermore, compared with most of the microstepping drivers in the market, both the driver heating and motor heating have been reduced by 15-30%. |
Applications:
Suitable for a wide range of 3-phase stepping motors of Nema 17, 23 and 34, and usable for various kinds of machines, such as X-Y tables, labeling machines, laser cutters, engraving machines, and pick-place devices, etc. Extremely suitiable for applications which excpted to be low noise, low vibration, high speed and high precision. |

Details |
| PUL﹢(+5V) |
Pulse signal: in PUL/DIR mode, it represents pulse signal, effective for each upward - rising edge. |
| PUL- (PUL) |
| DIR+ (+5V) |
Direction signal: in PUL/DIR mode, it represents HIGH/LOW level signal. For reliable response, DIR must be ahead of PUL by 5ms at least, the initial motor direction is related with motor wiring, exchange any set of coil can reverse motor initial direction. |
| DIR- (DIR) |
| ENA+ (+5V) |
Enable signal: this signal is used for enabling/disabling the driver, high level for enabling the driver and low level for disabling the driver. |
| ENA- (ENA) |
Remark: The 3MD560 can not accept CW/CCW input signals, while the 3MD560-CCW model can. Please note this difference when you place an order. |
