CACR stands for Yasnac VS800 full digital AC servo amplifier specially designed for robot and CNC feed axis closed-loop motion control.SR supports three parameter-selectable control modes: ±10VDC analog speed control, torque control and parameter-enabled position control.10 indicates rated matching motor power 1.0kW with continuous rated output current 7.6Arms under AC200V input class.SZ represents robot-specified PCB and housing structure with exclusive customized internal circuit, differing from SB/BB/BY standard series; dedicated optimized peripheral circuit for robot application.1 defines power supply specification: three-phase AC200~230V main power plus independent single-phase AC200~230V separated control power supply.S means only ±10VDC analog speed/torque command input without built-in differential pulse receiving hardware.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 reset function is restricted by software lock.

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 run continuously 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 operation.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.S-type hardware only accepts ±10VDC analog command without pulse input channel; position control function can be enabled via parameters while core position-related parameters are locked by F customized firmware.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 robot-oriented fixed setting preset by factory 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 robot dedicated fixed OEM signal definition under F firmware lock, arbitrary reallocation of I/O functions is prohibited.CN2: dedicated connector exclusively for incremental encoder feedback cable.

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-load and frequent emergency stop working conditions.

CACR-SR10SZ1SF is robot customized special model with unique SZ hardware circuit, cannot be directly substituted with SB standard series servo drives; only identical full part number CACR-SR10SZ1SF 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 casing 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 equipment abnormal operation.

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 or damaged feedback cable.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 normal firmware protection design instead of drive hardware damage. Overload alarm triggers when actual mechanical load exceeds motor rated output; inspect stuck transmission mechanism or reduce processing load accordingly.
