Description

1. MODEL CODE DEFINITION

CACR: Yasnac VS800 full digital AC servo amplifier for CNC feed axis closed-loop control
SR: Triple control mode: ±10VDC analog speed/torque + differential pulse position control (parameter switchable)
10: Matched motor power 1.0kW, 200V grade, rated continuous output current: 7.6Arms
BY: Exclusive PCB/housing layout, built-in standard dynamic braking circuit (power circuit differs from BB/BE type)
1: Power input spec: 3Φ AC200~230V main power + independent single-phase AC200~230V separated control power supply
S: Single incremental encoder hardware; CN2 only accepts incremental encoder feedback, no serial absolute encoder support
G: Standard open universal firmware（Core difference vs former F-type）: all parameters fully unlocked, full auto-tuning available, unrestricted I/O remapping; F firmware locks partial gain & OEM parameters, G is full open standard version
-E: Global export standard specification, non-OEM custom, factory default standard I/O definition, universal market general model (opposite to locked -C custom suffix)

2. ELECTRICAL PARAMETERS

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

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

  • Rated continuous output:7.6Arms; 150% overload sustainable 60s, 300% peak overload limited within 3s

  • DC bus working voltage: DC280~320V; P & BN terminals for external regenerative brake resistor

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

3. ENVIRONMENT & INSTALLATION

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

  • Humidity:5%~80%RH non-condensation; Protection class IP20, vertical cabinet mounting only

  • Altitude: ≤1000m full load; load derating required over 1000m elevation

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

4. CONTROL FEATURES (Core advantage of G firmware vs F firmware)

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

  2. Dual command input: analog ±10V speed/torque + differential pulse position signal

  3. Full unrestricted auto-tuning: complete motor parameter auto-identification, all gain parameters freely modified on-site（F-version partially locked auto-tune）

  4. CN1 digital I/O: full free parameter remapping for input/output definition, no fixed OEM logic restriction (big difference from -C custom model)

  5. RS422 serial communication: full parameter upload/download, runtime data & fault history reading without parameter lock

  6. Built-in digital notch filter to eliminate mechanical resonance & low-speed crawling

5. TERMINAL DESCRIPTION

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

  • P/BN: External regenerative braking resistor connection terminals (for frequent rapid deceleration & heavy cutting)

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

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

6. PROTECTION FUNCTIONS

Complete protection list: overcurrent, DC bus overvoltage/undervoltage, drive overheat, encoder break, motor overload; automatically stores latest 10 history fault codes.
Built-in internal dynamic brake for regular deceleration; external regenerative resistor needed between P-BN under continuous heavy-duty emergency stop operation.

7. REPLACEMENT GUIDANCE

  1. Direct interchangeable with same part number CACR-SR10BY1SG-E; cannot directly replace CACR-SR10BY1SF-E (F locked firmware vs G open firmware, parameter setting difference)

  2. Cannot substitute -C suffix custom CACR-SR10BY1SG-C (OEM fixed I/O & locked parameters)

8. MAINTENANCE & FAULT CHECK

  • Power off ≥15min to discharge internal capacitor before cabinet disassembly for maintenance to avoid electric shock

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

  • Full factory parameter initialization is allowed on G-E model (prohibited on C/OEM customized models)

  • Common alarms:

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

    • Encoder error: loose CN2 plug / damaged encoder cable / mismatched incremental encoder spec

    • Overvoltage: frequent heavy-load quick deceleration → add external brake resistor on P-BN
