Technical Write-Up: ESDA Servo Motor & Drive System Manual 1. Overview The ESDA series AC servo system is designed for high-precision motion control applications. It integrates a permanent magnet synchronous motor (PMSM) with a digital AC servo drive. Common applications include CNC machinery, textile equipment, packaging machines, robotic axes, and industrial automation retrofits. Key Features:
Control Modes: Position, Speed, Torque, and Hybrid modes. Feedback: Standard 2500-line incremental encoder (or optional 17-bit/23-bit absolute encoder). Input Voltage: Single-phase or three-phase 220V AC (or 380V for high-power models). Communication: Pulse direction (CW/CCW), analog ±10V, or RS-485 (Modbus RTU).
2. Mechanical Installation 2.1 Servo Motor
Mounting Orientation: Any angle, but ensure the cable gland faces downward to prevent oil/water ingress. Shaft Care: Do not hammer the shaft; use a coupling to avoid bearing damage. Ventilation: Leave 10mm clearance around the motor housing for cooling. Environmental: IP65 (except shaft output and connector). Avoid corrosive gases or excessive dust. esda servo motor manual
2.2 Servo Drive
Panel Mounting: Install vertically inside an IP20 or higher enclosure. Heat Dissipation: Maintain 30mm clearance above/below. Use external fans if ambient >45°C. Vibration: Keep below 0.5G (5-55Hz).
3. Wiring Guidelines (Critical) | Terminal Block | Signal | Description | |----------------|--------|-------------| | R, S, T (or L1, L2) | Main power input | Connect AC supply via magnetic contactor | | P, Br, N | Regenerative resistor | Connect external brake resistor (if needed) | | U, V, W | Motor power | Phase order determines rotation direction | | P, N | DC bus | For common DC bus systems | | CN1 | I/O control | 50-pin connector: pulses, digital I/O, analog | | CN2 | Encoder | Shielded twisted-pair cable required | | CN3 | RS-485 | Modbus RTU communication | Warnings: Technical Write-Up: ESDA Servo Motor & Drive System
Use a separate isolated power supply for control signals. Keep motor power cables >30cm away from signal cables. Ground the drive and motor to a common star point (resistance <100Ω).
4. Basic Parameter Configuration 4.1 Essential Parameters (Example) | Parameter | Name | Typical Value | Description | |-----------|------|---------------|-------------| | Pn000 | Control mode | 1 (Position) | 0: Speed, 1: Position, 2: Torque | | Pn001 | Pulse input type | 0 (CW/CCW) | 1: Pulse+Dir, 2: A/B phase | | Pn002 | Electronic gear ratio numerator | 1 | Set to match machine pitch | | Pn003 | Electronic gear ratio denominator | 1 | Example: 1000 pulses/rev = 1/1 | | Pn004 | Servo ON status | 1 | 0: Disable, 1: Enable at power-up | | Pn005 | Position error limit | 10000 | Pulses before alarm occurs | 4.2 Auto-Tuning Most ESDA drives feature a one-click auto-tuning :
Set Pn006 = 1 (auto-tuning mode). Issue a small JOG command. The drive calculates inertia ratio and sets Pn007 automatically. Fine-tune Pn008 (stiffness) if overshoot occurs. Input Voltage: Single-phase or three-phase 220V AC (or
5. Operating Modes 5.1 Position Mode (most common)
Input: Step/direction pulses (max 500 kHz). Applications: XYZ tables, pick-and-place, engraving. Diagnostics: Monitor Pn080 (feedback pulses) vs. command pulses.
