CACR stands for Yasnac VS800 full digital AC servo amplifier for CNC feed axis closed-loop motion control.SR supports three parameter-switchable control modes: ±10VDC analog speed control, torque control and differential pulse position control.10 represents rated matched motor power 1.0kW with continuous rated output current 7.6Arms under AC200V input grade.SB refers to compact PCB and housing structure with built-in standard dynamic braking circuit, different internal circuit layout from BB/BY/BZ series.1 defines power supply specification: three-phase AC200~230V main power plus independent single-phase AC200~230V separated control power supply.D means dual command input hardware compatible with both ±10VDC analog signal and differential pulse position command, with optimized external encoder power supply circuit design.F is factory-locked firmware; core loop gain, encoder and partial I/O parameters are pre-set and write-protected at factory, full factory parameter initialization function is locked by software restriction.

Main input power: three-phase AC200V~230V, allowable voltage fluctuation -15%~+10%, compatible with 50Hz/60Hz industrial power grid. Control power requires separate single-phase AC200~230V independent wiring to isolate surge interference from main circuit.Continuous rated output current:7.6Arms; 150% overload can continuously run for 60 seconds, 300% instantaneous peak overload limited within 3 seconds for motor startup acceleration. Normal DC bus operating voltage DC280V~DC320V; terminals P and BN reserved for external regenerative braking resistor connection for frequent rapid deceleration and heavy-duty machining.IGBT sine-wave PWM modulation is adopted with maximum output frequency up to 300Hz; encoder matching parameters are fixed and locked under F firmware configuration.

Operating ambient temperature:0℃~+55℃; storage temperature: -20℃~+70℃. Working relative humidity 5%~80%RH without dew condensation; protection grade IP20, vertical upright installation inside electrical cabinet is required.Max allowable installation altitude below 1000 meters above sea level; load derating required when installed over 1000m elevation. Anti-vibration specification:10Hz~55Hz with 0.5mm single amplitude during stable operation; net weight approx 3.0kg.

Speed adjustment ratio reaches 1:5000, full-load steady speed deviation controlled within ±0.01%. Built-in digital notch filter suppresses mechanical resonance and low-speed crawling during frequent start-stop cycles.D-type dual input hardware supports free switching between analog ±10VDC command and differential pulse command via parameter setup; position control function is fully available.Auto-tuning function is partially restricted: complete full automatic motor parameter identification is disabled, only minor fine-tuning of partial auxiliary gain is permitted for slight on-site mechanical matching; all CN1 I/O definition follows factory fixed setting of F version and cannot be arbitrarily redefined via parameters.Onboard RS422 serial communication supports real-time runtime data reading and historical fault record inquiry; locked core F parameters cannot be modified through communication cable.

R/S/T: three-phase main AC power input terminals; U/V/W: three-phase output terminals connecting servo motor stator cable; P/BN: external regenerative brake resistor wiring terminals for regenerative energy dissipation during repeated fast deceleration and emergency stop.CN1: opto-isolated digital I/O terminal block with fixed factory preset signal definition under F firmware lock, arbitrary reallocation of I/O functions is prohibited.CN2: dedicated connector exclusively for incremental encoder feedback cable with improved power supply circuit for external encoder accessory.

Complete built-in protection includes overcurrent protection, DC bus overvoltage/undervoltage protection, drive overheat protection, encoder disconnection protection and motor overload protection. The servo automatically stores latest 10 groups of historical fault codes for maintenance inspection; F preset parameters remain unchanged after power-off or fault reset operation.Built-in standard dynamic braking circuit handles regular deceleration energy consumption; external regenerative resistor must be installed between P and BN terminals under long-time heavy cutting and repeated emergency stop working conditions.

CACR-SR10SB1DF cannot be directly substituted with AF analog-only input or BF standard dual-input models due to D-type special encoder peripheral circuit; only identical full part number CACR-SR10SB1DF supports plug-and-play replacement.

Check wiring tightness of power cables, motor cable and CN1/CN2 connectors before every startup to eliminate poor-contact-induced faults. Clean radiator fin dust every 3~6 months to guarantee heat dissipation efficiency and avoid overheat alarm.Cut off all AC power supply and wait over 15 minutes for internal DC bus capacitor full discharge before opening drive housing for maintenance to prevent electric shock hazard. Random full factory parameter reset is strictly forbidden to avoid loss of F factory preset matching parameters and machine malfunction.

Overheat alarm mainly caused by radiator dust clogging, poor cabinet ventilation or long-term overloaded running; encoder fault alarm mostly triggered by loose CN2 plug, damaged feedback cable or abnormal external encoder power supply.Overvoltage alarm occurs during frequent heavy-load rapid deceleration; resolve by installing external regenerative resistor between P and BN terminals. Parameter write failure when modifying F-version locked core parameters belongs to firmware protection instead of hardware damage; overload alarm triggers when actual mechanical load exceeds motor rated output, inspect stuck transmission mechanism or reduce processing load accordingly.
