An instruction manual
Product introduction
- Summary
HB860H is a new type of hybrid servo driver. It adopts the latest special motor control DSP chip and vector closed-loop control technology to overcome the problem of losing step of open-loop stepper motor thoroughly. It can also significantly improve the high-speed performance of the motor, reduce the heat level of the motor and reduce the vibration of the motor, so as to enhance the machine. The processing speed and accuracy and reduce the consumption of the machine. In addition, when the motor is continuously overloaded, the driver will output an alarm signal with the same reliability as the AC servo system. - Technical characteristics

The green LED is the power indicator, which is always on when the driver is connected to the power supply, and goes out when the driver is turned off. The red LED is the fault indicator. When the fault occurs, the indicator flashes in a cycle of 5 seconds. When the fault is cleared by the user, the red RED goes out for a long time. The flashing frequency of red LED is 2Hz, of which LED is bright 200ms and 300ms is eliminated. Red LED flashes in 5 seconds.
Notes:
- t1:ENA (enabling signal) should be DIR at least 5μs in advance. In general, it is recommended that ENA+ and ENA- be suspended.
- t2:DIR At least PUL ahead of time, the falling edge 5μs determines its state is high or low.
- t3:The pulse width is not less than 2.5μs.
- t4: Low level width is less than 2.5μs.
3.、Serial port connection

Dial switch settings
The driver uses a six-digit dialing switch to set the subdivision accuracy, the control signal along the effective direction of rotation and the motor setting, which is described in detail as follows:

Subdivision setting
| Step / circle | SW1 | SW2 | SW3 | SW4 |
| Defauit | on | on | on | on |
| 400 | on | on | on | on |
| 800 | off | on | on | on |
| 1600 | on | off | on | on |
| 3200 | off | off | on | on |
| 6400 | on | on | off | on |
| 12800 | off | on | off | on |
| 25600 | on | off | off | on |
| 51200 | off | off | off | on |
| 1000 | on | on | on | off |
| 2000 | off | on | on | off |
| 4000 | on | off | on | off |
| 5000 | off | off | on | off |
| 8000 | on | on | off | off |
| 10000 | off | on | off | off |
| 20000 | on | off | off | off |
| 40000 | off | off | off | off |
Driver parameter setting
The parameter setting of HB860H drive must be modified through the connection between special debugger and RS232 serial communication port. There is a set of best default factory configuration parameters of corresponding motor in the drive. Users only need to adjust the internal subdivision of the drive according to the specific usage. Please check the debugger usage. bright
Note: The default parameters of current loop, position loop and speed loop are the best parameters of the matching motor. Customers do not need to modify them. They only need to select the motor subdivision and the percentage of open and closed loop current according to the need of system control. For example, in the case of belt drive, it is necessary to adjust the rigidity of motor, current loop, position loop and speed loop to improve the effect. If unable to adjust to the best effect, we can call our service telephone for consultation and adjustment, we have professional and technical personnel to solve such problems for you.
Typical application wiring diagram
The typical wiring diagram of the DC servo system composed of HB860H drivers is shown in Figure 7. The power supply is recommended for the size range. The higher the voltage, the better the high speed performance.
