The kit includes dedicated motor and encoder cables for reliable connection between the servo motor and driver. The encoder cable is crucial for utilizing the multi-turn absolute encoder functionality, especially when used with a battery box.
4. Installation and Wiring
4.1 Mounting
Mount the servo driver in a well-ventilated enclosure to ensure adequate heat dissipation. Secure the servo motor to a stable surface using appropriate fasteners, ensuring proper alignment with the load. Avoid mounting in areas subject to excessive vibration, dust, or moisture.
4.2 Wiring Connections
All wiring should be performed with the power supply disconnected. Refer to the wiring diagram below for correct connections. Ensure all connections are secure to prevent intermittent operation or damage.
Figure 5: STEPPERONLINE A6 Series Wiring Diagram. This diagram illustrates the power input connections for the 100W/400W/750W servo drivers, showing L1, L2, P, C, N, U, V, W, and PE terminals.
Power Wiring: Connect the single-phase 220VAC power supply to the L1 and L2 terminals of the servo driver. Ensure the protective earth (PE) terminal is properly grounded.
Motor Wiring: Connect the motor power cable to the U, V, W terminals on the driver and the corresponding terminals on the motor. The motor cable also includes connections for the motor brake, if applicable.
Encoder Wiring: Connect the encoder cable from the motor's encoder port to the CN2 port on the servo driver. This connection is vital for feedback and absolute positioning. For multi-turn absolute encoder functionality, ensure the 3m encoder cable with a battery box is used.
Control Signal Wiring: Connect pulse, direction, and enable signals to the CN1 port as per your control system requirements. The driver supports Pulse, RS485, and Analog communication interfaces.
5. Operating Modes
The A6 series servo driver supports various control modes to suit different application needs. These include:
- Position Control Mode
- Velocity Control Mode
- Torque Control Mode
- Position-Velocity Mode
- Position-Torque Mode
- Torque-Velocity Mode
- Position-Velocity-Torque Mode (Dual Mode Switching)
Configuration of these modes and their parameters is typically done via software provided by STEPPERONLINE or through the driver's built-in interface. Refer to the detailed programming manual for specific parameter settings and communication protocols (Pulse, RS485, Analog).
