How to Control Servo Motor with Delta PLC (Full Step-by-Step Guide)

In modern industrial automation, precision control is everything. From robotic arms to CNC machines, packaging lines, and conveyor systems – servo motors play a critical role in achieving speed, accuracy, and synchronization. When combined with a Delta PLC (Programmable Logic Controller), they create a powerful automation system capable of delivering smooth motion and intelligent control.

If you’re looking to control a servo motor using Delta PLC, this comprehensive guide will walk you through everything – from connection setup, wiring, and software configuration to real-world applications.
At the end, you’ll also find links to download essential Delta PLC and HMI software directly from PLCUnlock.com, your trusted source for industrial automation software and licenses.

What is a Servo Motor?

A servo motor is a closed-loop motion control device that provides precise control of angular or linear position, velocity, and acceleration. Unlike regular induction motors, servo motors are equipped with:

  • Encoder feedback
  • Dedicated servo drive
  • Precise torque control

They are used in:

  • Robotics and CNC machines
  • Conveyor systems
  • Labeling and packaging equipment
  • Pick-and-place machines
  • Automated assembly systems

Why Use a Delta PLC to Control Servo Motors?

Delta PLCs are widely known for their reliability, affordability, and flexibility in automation applications. The combination of a Delta PLC and Delta ASDA servo drive gives you a powerful motion control solution that can be easily programmed and integrated with Delta HMI for visualization.

Key Advantages:

  • High-speed communication via RS-485, CANopen, or EtherCAT
  • Easy programming using WPLSoft or ISPSoft software
  • Precise motion control with feedback loops
  • Compatibility with Delta HMI software like DOPSoft
  • Seamless integration with other automation brands

If you don’t yet have Delta programming software, you can easily Download DOPSoft V4.11.22 – Delta HMI Software Free from our website to start your configuration.

Components You’ll Need

Before starting the connection, gather the following components:

  1. Delta PLC (e.g., DVP Series, AH Series, or AS Series)
  2. Delta Servo Drive (e.g., ASDA-B2 or ASDA-A2 Series)
  3. Delta Servo Motor compatible with the drive
  4. Communication cable (RS-485 or pulse output cable)
  5. Power supply unit
  6. PC with WPLSoft or ISPSoft installed
  7. Delta HMI (optional) for monitoring

Step 1: Wiring the Delta PLC with the Servo Drive

The first and most critical part is proper wiring between your PLC and the servo drive.

Pulse Control Connection

If you’re using a Delta DVP PLC:

  • Connect Y0 to the Pulse+ terminal on the servo drive.
  • Connect Y1 to the Direction+ terminal.
  • Common ground to COM terminal.

Ensure:

  • The pulse output is configured as high-speed output in the PLC program.
  • The servo drive input type matches (pulse + direction or CW/CCW).

Step 2: Setting Servo Parameters

Use the ASDA Soft software (available from Delta) or manually set parameters on the drive keypad.

Important parameters:

  • Pn000: Control mode (set to pulse mode or RS-485 mode)
  • Pn001: Pulse input selection
  • Pn002: Direction logic
  • Pn003: Electronic gear ratio

Once parameters are configured, the servo drive is ready to accept signals from the PLC.

Step 3: Configuring Delta PLC Software

For programming, use WPLSoft or ISPSoft – Delta’s official PLC software.
You can Download Delta ISPSoft Software Free from our website to get started.

PLC Program Example:

Here’s a simple pulse control example:

LD M0

OUT Y0

LD M0

OUT Y1

Explanation:

  • When M0 turns ON, the PLC outputs pulses through Y0 to the servo drive.
  • Direction is controlled through Y1.

You can use high-speed pulse instructions (PTO/PWM) for more complex motion control.

Step 4: Testing and Motion Verification

  1. Power up the system.
  2. Turn the servo to ON mode.
  3. Run the PLC program to send pulses.
  4. Observe motor movement – it should rotate smoothly in one direction.
  5. Reverse direction logic to verify bidirectional motion.

You can also link your Delta PLC with Delta HMI (DOP Series) using DOPSoft, allowing real-time control and monitoring.

Step 5: Integrating Delta HMI for Visualization

To create a user-friendly interface:

  1. Launch DOPSoft.
  2. Connect to your Delta HMI via USB or Ethernet.
  3. Create control buttons for:
    • Servo ON/OFF
    • Start/Stop movement
    • Direction control
    • Speed adjustment

This makes your servo control system more professional and easy to operate.

Step 6: Advanced Motion Control with Delta PLC

Delta PLCs (especially AH and AS Series) can handle multi-axis servo control using high-speed pulse or communication protocols like EtherCAT.

Advanced features include:

  • S-curve acceleration/deceleration
  • Position synchronization
  • Electronic cam control
  • Multi-axis interpolation

For large-scale motion systems, Delta’s ASDA Soft and ISPSoft are ideal.
