Q2BYG806CM/Q2BYG808CM is a high-performance stepper motor driver produced by Zhongweixing Company. It adopts a new bipolar constant current PWM drive technology, which can output faster speed and greater torque than other drive methods. The fine-dividing function improves the accuracy of motor operation, reduces vibration, and reduces noise. This drive has a beautiful appearance, excellent design, and reliable performance. It is your ideal choice.
This manual provides installation, wiring, configuration and troubleshooting information for the Q2BYG80VACM/Q2BYG808CM series stepper motor drivers. The drivers support two‑phase four, six or eight‑wire hybrid stepper motors with a supply voltage of 40‑80 V DC and a maximum per‑phase current of 8 A.
Key features include bipolar constant‑current chopper control, selectable micro‑stepping up to 128×, dual‑pulse and single‑pulse control modes, and built‑in fault protection. The document details pin functions, power supply requirements, parameter settings, and safety precautions for reliable operation. This manual is written in Chinese.
| Supply voltage (DC) | 40‑80 V |
|---|---|
| Maximum phase current | 8 A |
| Output phase current range | 2.5‑8.0 A |
| Step pulse frequency | 0‑300 kHz |
| Insulation resistance | 500 MΩ |
| Operating temperature range | -20 °C to 70 °C |

Set the driver current to about 1.2 times the motor’s rated current.
Swap the connections of the A+ and A‑ terminals on the driver.
Insert a 3 kΩ resistor in series with the 24 VDC control line; for a 12 VDC line use a 2 kΩ resistor.
No, the driver requires a supply voltage between 40 VDC and 80 VDC for proper operation.
