Description

1. Model Code Definition

CACR: Yasnac VS800 full digital CNC AC servo amplifier for machine tool feed axis control
SR: 3 selectable control modes via parameter: ±10VDC analog speed / torque / differential pulse position control
10: Rated matching motor power 1.0kW, rated continuous output current:7.6Arms, AC200V class power input
SB: Compact cabinet + built-in internal dynamic braking circuit, standard housing structure
1: Power specification: 3Φ AC200~230V main power + independent single-phase AC200~230V control power supply
G: Only single ±10VDC analog speed/torque command input (NO differential pulse position hardware circuit onboard; different from D/DF dual-input version)
F: Factory fixed locked firmware; core gain, encoder matching & default I/O parameters pre-set & write-protected at factory

2. Main Electrical Ratings

  • Main input: 3-phase AC200~230V, tolerance -15%~+10%, 50/60Hz

  • Control power: separate single-phase AC200~230V independent wiring

  • Overload characteristic: 150% rated current sustainable for 60s; 300% peak overload limited within 3s

  • DC bus normal voltage: DC280~320V; P/BN terminals for external regenerative brake resistor connection

  • Drive mode: IGBT sine-wave PWM modulation, max output frequency 300Hz

3. Working Environment

  • Operating ambient temp: 0℃ ~ +55℃; storage temp: -20℃ ~ +70℃

  • Humidity:5%~80%RH non-condensation; protection grade IP20, vertical cabinet installation required

  • Max installation altitude ≤1000m; derating needed over 1000m elevation

  • Anti-vibration: 10~55Hz, 0.5mm single amplitude; net weight approx 3.0kg

4. Control Feature (Core difference from DF model)

  1. G hardware only supports analog ±10VDC speed/torque command input, no onboard pulse receiving circuit; cannot use pulse position control directly

  2. Speed adjustment range 1:5000, full-load speed fluctuation ≤±0.01%

  3. Built-in digital anti-resonance notch filter to eliminate mechanical low-speed vibration

  4. Partial auto-tuning available: only minor auxiliary gain fine-adjustment; full motor parameter auto-identify locked by F factory firmware

  5. Onboard RS422 communication: read running data & fault history; core locked parameters cannot be modified via communication

5. Terminal Definition

  • R/S/T: 3-phase main AC power input; U/V/W: servo motor 3-phase power output

  • P/BN: External regenerative braking resistor terminals for frequent rapid deceleration & heavy load operation

  • CN1: Opto-isolated digital I/O terminal block, fixed factory I/O definition (unmodifiable for F firmware version)

  • CN2: Exclusive incremental encoder feedback connector, standard 5V encoder power output

6. Complete Protection Functions

Overcurrent, DC bus overvoltage/undervoltage, drive overheat, encoder disconnection, motor overload protection; stores latest 10 fault codes for maintenance.
Standard built-in dynamic brake for normal deceleration; add external resistor between P-BN under frequent emergency stop & heavy cutting working condition.

7. Replacement Notice

CACR-SR10SB1GF is analog-only input type, cannot replace DF/D dual pulse+analog model due to missing pulse input hardware; only identical part number CACR-SR10SB1GF for plug-and-play replacement.

8. Routine Maintenance

  1. Check all power & CN1/CN2 wiring tightness before startup

  2. Clean radiator dust every 3~6 months to avoid overheat alarm

  3. Cut all power and wait ≥15min for DC capacitor full discharge before opening casing for maintenance; forbidden full factory parameter reset (F-version fixed data will be lost)

9. Common Fault Troubleshooting

  • OH Overheat: blocked radiator dust / poor cabinet ventilation / long-term overload

  • PG Fault: loose CN2 plug, damaged encoder cable

  • OV Overvoltage: frequent heavy-load quick deceleration → install external brake resistor at P-BN

  • Parameter write failure: trying to edit F-locked core parameters (firmware protection, not hardware failure)
