Particularly effective in applications requiring low noise operation and high-speed performance.
Setting of DIP Switch:
The PC86 digital integrated low-voltage servo driver features an 8-bit DIP switch for setting subdivision precision (electronic gear ratio), motor rotation direction, self-test, and function mode selection. Details are as follows:
| Pulse/rev | SW1 | SW2 | SW3 | SW4 |
| Default | 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 |
SW5 controls motor direction: ON activates clockwise rotation (CW), OFF activates counterclockwise rotation (CCW).
SW6 rigidity setting: When OFF, the actuator is rigid; when ON, it is less rigid.
SW7~ SW8 motor housing selection:
| Motor | SW7 | SW8 |
| | ON | ON |
| 86-45 | OFF | ON |
| 86-85 | ON | OFF |
| 86-120 | OFF | OFF |
Frequently Asked Questions
1. Common Issues in Applications and Their Solutions
| Phenomenon | Potential issues | Countermeasure |
| The motor is not turning. | The power light is not on. | Check the power supply circuit. Power supply is normal. |
| Motor shaft force | The pulse signal is weak, and the signal current increases to 7-16mA. |
| Subdivision is too small | Select the correct subcategory |
| The drive is protected | Power on again |
| Enable signal is low | This signal is pulled up or disconnected |
| No response to control signal | Not powered on |
| The motor circuit is open. | check and connect |
| The voltage is either too high or too low. | Check the power supply |
| Motor or driver damaged | Replace the motor or driver |
| Location is inaccurate | The signal is interfered with. | suppress interference |
| The shielded ground is not connected or not properly connected. | reliable grounding |
| The motor circuit is open. | check and connect |
| Subsection error | Set subdivision |
| motor stall during acceleration | The acceleration time is too short | prolonged acceleration time |
| The motor torque is too low | Select a high-torque motor |
| Low voltage | Appropriately increase the voltage |
Driver FAQ
1) What are the advantages of segmented servo drives?
●By reducing the step angle per step, the step uniformity is improved, thus enhancing control precision.
●It can significantly reduce motor vibration. Low-frequency oscillation is an inherent characteristic of stepper motors, and microstepping is the most effective method to eliminate it.
●It can effectively reduce torque pulsation and improve output torque.
These advantages are widely recognized by users and deliver tangible benefits, making it advisable to choose a segmented drive.
2) Why does my motor only rotate in one direction?
●The directional signal may be too weak, or the wiring polarity is incorrect, or the signal voltage is too high, which could burn out the directional current-limiting resistor.
●The pulse mode is mismatched. The signal is pulse/direction. The driver must be set to this mode.
