5. Setup
5.1 Wiring Connections
Careful wiring is crucial for the proper and safe operation of the servo system. Refer to the following diagrams for correct connections.
Figure 5.1.1: General Wiring Diagram for Single-phase AC 220V.
Figure 5.1.2: Control Terminal CN1 Pinout.
Motor Winding and Encoder Connections:
Figure 5.1.3: Motor Winding and Encoder Socket Wiring.
- The motor winding plug is designed to prevent flying and splashing water.
- The motor wire does not include an adapter plug, which reduces the chance of poor contact.
5.2 Initial Power-Up
After all connections are securely made, apply power to the servo driver. Observe the display for any error codes. If an error occurs, refer to the Troubleshooting section.
6. Operating Instructions
The SDF08NK8X1 servo driver supports multiple control modes and offers extensive parameter customization.
6.1 Control Modes
The driver supports the following control modes:
- Position Control: For precise positioning applications.
