SGDC-15AJA
Description
1. Model Definition & Product Overview
SGDC: Compact shared DC-bus servo series (different from AC input SGDB series)
15: Rated output power 1.5kW
A: Dual command hardware supporting pulse position input and ±10VDC analog speed/torque input
J: Internal circuit optimized for common DC-bus power supply
A: Standard universal factory firmware, all parameters fully adjustable without fixed OEM preset values
2. Electrical Ratings
Main power input: Shared DC bus DC280~330V; separate terminal for independent control auxiliary power supply
Rated continuous output: 1.5kW, 3-phase AC 0~230V PWM output, 300% short-time overload capacity for instant startup and shock load
Standard built-in dynamic braking circuit; external brake resistor can be equipped under frequent high-speed deceleration conditions.
3. Control Modes & Interfaces
Pulse position control: Accept open-collector or differential line driver pulse (CW/CCW dual pulse / A/B quadrature pulse); electronic gear ratio fully configurable.
Analog speed/torque control: Receives external ±10VDC analog reference; gain and offset parameters are fully editable.
MECHATROLINK-I hardware reserved on PCB; bus function can be enabled by parameter setup as required.
CN1: Standard universal I/O terminals including Servo ON, fault reset, positioning complete output, dry-contact alarm relay output with standard pin definition.
CN2: Dedicated port for incremental / absolute encoder connection.
RS232 port for SigmaWin software to upload/download parameters, monitor real-time operation and read historical fault data.
4. Protection Functions
