3. RY414 extra feature: Extended dedicated command port for external main controller high-speed pulse command, special serial encoder signal conversion, customized multi-channel digital I/O for OEM equipment synchronization (unique hardware definition different from standard CN1 connector)

4. Analog reference: ±10VDC for speed/torque command input

5. Encoder: Compatible with 13-bit incremental encoder; optional absolute encoder with backup battery

6. Communication: Standard RS485 for SigmaWin+ tuning software; RY414 adds proprietary dedicated communication interface instead of standard fieldbus slot

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

• Overall dimension: H180 × W100 × D155mm; net weight approx.2.7kg

4. Installation & Wiring Rules

1. Vertical panel mounting; reserve ≥35mm top/bottom & ≥25mm left/right clearance for heat dissipation.

2. Cut all power supply and wait ≥10min for internal DC bus capacitor discharge before wiring/maintenance to avoid electric shock hazard.

3. Main circuit terminals R/S/T connect AC220V input; U/V/W connect 3-phase servo motor winding; PE terminal reliably earth to cabinet ground bar.

4. Separate high-power motor cable and shielded control/encoder/RY414 signal cable to eliminate EMI interference; all shielded cables single-end grounded.

5. RY414 dedicated wiring follows OEM customized pin definition (non-standard CN1 pinout, refer to RY414 accessory manual).

5. Commissioning Procedure

1. Complete full wiring inspection to eliminate short-circuit or reversed connection before power-on.

2. Power on for drive self-diagnosis, execute no-load auto-tuning to read motor coil & encoder parameters automatically.

3. Select target control mode via parameter setting; set electronic gear ratio (position mode) or speed/torque loop gain accordingly; configure RY414 related dedicated parameters for external controller communication.

4. Run low-speed no-load jog test first; switch to formal loaded operation after stable trial running.

6. Common Fault & Troubleshooting

• OC Overcurrent Alarm: Check motor U/V/W short circuit, damaged winding or wrong power wiring

• Encoder Fault: Inspect loose encoder connector, broken shield wire or mismatched pin wiring; also check RY414 interface cable connection

• UV Undervoltage: AC220V input voltage drop or insufficient source capacity

• OH Overheat: Cooling fan damage, blocked ventilation duct or continuous overload; clean internal dust and reduce mechanical load

  Clear fault by full power cycle after root cause removed.

7. Regular Maintenance

• Clean cooling fan and internal dust every 3~6 months per on-site environment; retighten loose terminal screws periodically.

• For storage over 12 months, perform 30min no-load preheating power-on before formal commissioning.
