• Compatible motor power range: 7.5kW ~ 15kW 400V ELAU SM series heavy-duty servo motors
• PWM carrier frequency: Base 8kHz, adjustable up to 16kHz for low-noise low-speed running
• Output frequency range: 0–600Hz, compatible with high-speed spindle servo motors
• Output voltage: 0–480V AC 3-phase sine wave

Control Architecture

1. Absolute / relative position positioning mode
2. Variable speed regulation mode
3. Torque-limited tension control mode

   Auto motor parameter recognition via motor electronic nameplate, no manual tuning required

4. Communication & Feedback Interfaces

Encoder Feedback

• Incremental encoders
• S1 single-turn / M1 multi-turn SinCos absolute encoders (standard for SM series motors)

Fieldbus Communication
