1. Product Overview

2. Electrical Specifications

2.1 Power Ratings

• Matched motor rated power: 5W

• Main power supply input: DC24V, rated input current 2.9A

• Three-phase output: adjustable low-voltage AC for 5W miniature servo motor

• Cooling type: passive natural heat dissipation without built-in cooling fan

• Certification: CE compliant

2.2 Control Configuration

• Control mode fixed as Pulse Position Control only (no analog speed/torque control available per CP customization)

• Command input: open-collector or differential pulse train positioning signal from upper controller

• Encoder interface: dedicated connector for incremental encoder paired with SGMM-B5C servo motor

• Debug interface: ERSPRO dedicated network port for parameter upload/download via Yaskawa official debugging software

• I/O terminals: CP customized pin assignment deviates from standard SGDF-B5C wiring definition, strictly follow factory custom wiring document for terminal layout

2.3 Environmental Conditions

• Operating ambient temperature: 0°C ~ +55°C; storage temperature: -20°C ~ +70°C

• Relative humidity: ≤90% RH without condensation; avoid corrosive gas, combustible dust and liquid splashing

• Vibration resistance: 10~55Hz, maximum vibration acceleration ≤0.5G

3. Installation Instructions

1. Mount the servopack vertically onto solid metal DIN rail or mounting plate.

2. Keep clearance ≥30mm at top/bottom and ≥20mm on left/right for heat dissipation.

3. Install away from heat source and direct sunlight; fasten mounting screws tightly against mechanical vibration loosening.

4. Separate power cables and shielded control/encoder cables during wiring layout to reduce electromagnetic interference; connect PE grounding terminal reliably to equipment grounding bus.

4. Wiring Requirements

1. Cut off DC24V power supply and wait minimum 5 minutes for internal capacitor full discharge before wiring or maintenance to prevent electric shock hazard.

2. DC24V positive/negative polarity must not be reversed; reverse connection will permanently damage internal circuit.

3. Motor power terminals U/V/W connect to corresponding three-phase leads of matched 5W servo motor; secure encoder dedicated shielded cable connector tightly.

4. All position pulse input and digital I/O wiring shall comply with CP customized terminal drawing instead of standard SGDF series manual definition.

5. Commissioning Procedure

1. Double-check all wiring correctness before DC24V power-on for drive self-inspection.

2. Complete no-load motor parameter auto-tuning after power initialization to automatically identify motor winding and encoder parameters.

3. Set electronic gear ratio parameters according to required positioning resolution.

4. Perform no-load jog operation test first; switch to low-load formal operation after stable no-load running.

6. Fault Diagnosis & Troubleshooting

• Overcurrent Alarm: Power off and check short-circuit of motor U/V/W cable or damaged motor winding.

• Encoder Fault: Inspect loose connector, broken encoder cable or mismatched CP customized wire sequence.

• Undervoltage Alarm: Caused by insufficient DC24V power capacity or excessive voltage drop on power line.

• Overheat Alarm: Blocked heat sink or continuous overload; clean surface dust and reduce machine load.

  Reset fault by power cycle after eliminating fault root cause; contact professional maintenance if same alarm repeats continuously.

7. Periodic Maintenance

• Clean surface dust every 3~6 months based on on-site working environment; retighten loose terminal screws regularly.

• For long-term storage over 12 months in dry sealed environment, conduct 30-minute no-load power-on pre-test before field commissioning.
