Description

1. MODEL CODE EXPLANATION

CACR: Yasnac VS800 full-digital AC servo amplifier for CNC feed axis closed-loop control
SR: Multi-mode control: ±10V analog speed/torque + differential pulse position control, parameter-switchable control modes
10: Rated matching motor: 1.0kW, 200V class, continuous rated output: 7.6Arms
BY: Standard built-in dynamic braking circuit, dedicated PCB & housing layout (differs from BB/BE version power circuit)
1: Power supply definition: 3-phase AC200~230V main power + independent single-phase AC200~230V separate control power
S: Single incremental encoder hardware; CN2 only supports incremental encoder feedback, no serial absolute encoder compatible
F: F-version fixed firmware, partial gain/I/O parameters factory locked with limited adjustable range
-E: Standard export universal suffix (vs -C OEM customized): unlocked standard I/O definition, non-custom preset parameters, general market standard firmware, freely modify most parameters via panel or communication, no machine-locked OEM program

2. ELECTRICAL RATINGS

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

  • Control Power: Independent single-phase AC200~230V isolated power supply

  • Continuous Output Current: 7.6Arms; 150% overload sustainable 60s, 300% peak overload ≤3s

  • DC Bus Normal Voltage: DC280~320V; Terminals P & BN reserved for external regenerative braking resistor connection

  • Modulation: IGBT sine-wave PWM, max output frequency:300Hz

3. OPERATING ENVIRONMENT

  • Operating Temp: 0℃ ~ +55℃; Storage Temp: -20℃ ~ +70℃

  • Humidity: 5%~80%RH non-condensing; Protection Grade: IP20, vertical cabinet installation only

  • Altitude: ≤1000m without derating; derate load over 1000m above sea level

  • Vibration: 10~55Hz, 0.5mm single amplitude; Net Weight ≈3.0kg

4. CONTROL PERFORMANCE & FEATURES

  • Speed regulation ratio:1:5000, full-load speed fluctuation ≤±0.01%

  • Dual command input: ±10VDC analog speed/torque signal + differential pulse position command

  • Auto-tuning: Full motor parameter auto-identification available (unrestricted, different from -C locked OEM model); all gain parameters adjustable on-site

  • CN1 I/O: Standard factory default definition, users free to redefine input/output functions via parameter setting (-E core advantage vs -C fixed I/O)

  • Onboard RS422: Read runtime data, query fault history, upload/download full parameters without lock restriction

  • Built-in digital notch filter to suppress mechanical resonance & low-speed crawl during frequent start-stop

5. TERMINAL DEFINITION

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

  • P/BN: External regenerative brake resistor terminals for high-cycle rapid deceleration

  • CN1: Opto-isolated digital I/O connector (fully configurable under -E standard version)

  • CN2: Exclusive incremental encoder feedback connector (S single-encoder spec)

6. PROTECTION FUNCTIONS

Overcurrent, DC bus over/under voltage, drive overheat, encoder loss, motor overload protection; stores latest 10 fault codes automatically.
Standard internal dynamic brake for normal deceleration; install external resistor on P-BN under heavy-duty repeated emergency stop operation.

7. REPLACEMENT NOTE

CACR-SR10BY1SF-E is universal standard stock model, cannot be directly replaced by -C customized variant due to fixed OEM I/O/parameter in -C; interchangeable only with identical -E suffix unit or standard non-suffix CACR-SR10BY1SF.

8. MAINTENANCE GUIDE

  1. Cut all AC power and wait ≥15min for capacitor full discharge before disassembly to avoid electric shock.

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

  3. Full factory parameter reset is permitted for -E model (prohibited on -C OEM version).

9. COMMON FAULT DIAGNOSIS

  • Overheat: Radiator clogging, poor cabinet ventilation, continuous overload.

  • Encoder Alarm: Loose CN2 connector, damaged feedback cable, mismatched incremental encoder spec.

  • Overvoltage: Frequent heavy-load fast deceleration → add external brake resistor between P & BN.
