Description

1. Model Code Definition

CACR: Yasnac VS800 full digital AC servo amplifier for CNC/automation standard version
SR: Multi-mode control: ±10VDC analog speed/torque + differential pulse position command, parameter switchable
15: Rated power 1.5kW, 3Φ AC200V grade, continuous output current:9.7Arms
B: Standard universal main PCB (general standard board, non-custom OEM circuit vs T-type)
A: Standard fixed default base parameter group (factory standard parameter setting, no locked special gain)
1: AC200V input specification grade
AF: Standard universal CN2 incremental encoder interface + standard CN1 I/O pin definition, non-OEM customized firmware

2. Electrical Specifications

  • Main input: 3-phase AC200~230V, tolerance -15%~+10%, 50/60Hz; control power single-phase AC200V

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

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

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

  • Net weight≈3.4kg, IP20 indoor cabinet vertical mounting only

3. Ambient & Installation

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

  • Humidity:5%~80%RH non-condensing; power derating when altitude＞1000m above sea level

  • Vibration:10~55Hz, 0.5mm single amplitude continuous running

4. Control Performance

  • Speed adjustment ratio:1:5000; full-load speed variation ≤±0.01%

  • Built-in digital notch filter for mechanical resonance suppression

  • Dual command input freely switch: analog ±10VDC / line-driver differential pulse via internal parameters

    AF standard feature: All parameters fully editable, complete factory parameter reset allowed, full auto-tuning available (no firmware lock unlike Yxx custom suffix models)

  • Onboard RS422 communication: monitor runtime data + save latest 10 fault records, full parameter upload/download supported

5. Terminal & Connector Layout

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

  • P/BN: External dynamic/regenerative brake resistor terminals

  • CN1: Standard opto-isolated digital I/O terminal block, universal default signal mapping, I/O assignment adjustable via parameters

  • CN2: Standard AF universal incremental encoder socket, compatible with regular USAGED/USAFED incremental servo motor

  • Front 7-segment LED: real-time status + fault code display

6. Full Protection List

Overcurrent / DC bus overvoltage / DC undervoltage / heatsink overheat / encoder loss / motor overload / CPU malfunction protection
Built-in internal dynamic brake circuit for normal deceleration; add external braking resistor on P-BN for frequent rapid stop & heavy cyclic duty

7. Replacement Rule

CACR-SR15BA1AF is standard general-purpose model. Can substitute with same full part number CACR-SR15BA1AF; CACR-SR15BB1AF/BC1AF similar power can be cross-replaced after parameter reset & auto-tuning (different suffix only minor I/O difference). Custom TZ/Yxx suffix servo cannot direct plug-and-play.

8. Routine Maintenance

  1. Pre-operation check all power terminals & CN1/CN2 connector tightness

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

  3. Cut off AC power, wait ≥15min for DC bus capacitor full discharge before cabinet opening for maintenance (anti-shock risk)

  4. Standard AF version permits full factory parameter initialization when replacing equipment

9. Common Troubleshooting

  • Overheat alarm: blocked cooling fin / poor cabinet ventilation / continuous overload → clean cooling or reduce running load

  • Encoder error: loose CN2 plug / broken feedback cable → check wiring & motor encoder matching

  • Deceleration overvoltage: mount external brake resistor between P & BN terminals

  • Parameter modification failed: hardware damage (standard AF allows full parameter edit normally)

  • Overload alarm: mechanical jamming or excessive payload → inspect transmission mechanism

10. LED Fault Code

1=Overcurrent｜2=Main circuit fault｜3=DC Overvoltage｜4=DC Undervoltage｜5=Drive Overheat｜6=Encoder disconnect｜7=Motor Overload｜A=CPU abnormal｜B=Parameter error｜C=External E-Stop active
