Description
1. MODEL CODE DEFINITION
CACR stands for Yasnac VS800 full digital AC servo amplifier applied to CNC feed axis closed-loop motion control.SR supports three optional control modes including analog speed, torque and position control configurable via internal parameters.10 means matched rated motor power 1.0kW with continuous rated output current 7.6Arms under AC200V class.SB refers to exclusive compact PCB layout and housing structure, internal power circuit differs from BB/BY/BZ series with standard built-in dynamic braking circuit.1 defines power supply standard: three-phase AC200~230V main power plus independent single-phase AC200~230V separated control power supply.AF: A = only ±10VDC analog speed/torque command input, no hardware for differential pulse position signal reception; F = factory locked firmware, most loop gain and partial I/O parameters are write-protected with limited adjustable range, full factory parameter reset function is restricted.
2. ELECTRICAL SPECIFICATIONS
Main input power: three-phase AC200V~230V, permissible 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 under frequent rapid deceleration and heavy-duty machining.The drive adopts IGBT sine-wave PWM modulation with maximum output frequency up to 300Hz, encoder matching parameters preset and locked by F-version factory program.
3. INSTALLATION & ENVIRONMENT REQUIREMENT
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 mandatory.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.
4. CONTROL PERFORMANCE AND FEATURES
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.AF hardware only receives ±10VDC analog command without pulse input channel; position control function can be activated by parameter setting but core position relevant parameters are locked by F firmware.Auto-tuning function partially restricted: complete full automatic motor parameter identification is unavailable, only minor fine-tuning of partial gain parameters allowed for slight on-site mechanical matching; CN1 I/O definition follows factory fixed default setting and cannot be freely redefined via parameters.Onboard RS422 serial communication supports real-time runtime data reading and historical fault record inquiry; locked core parameters cannot be modified through communication port.
5. TERMINAL & CONNECTOR DESCRIPTION
R/S/T: three-phase main AC power input terminals; U/V/W: three-phase output terminals connecting servo motor power cable; P/BN: external regenerative brake resistor wiring terminals for energy dissipation during repeated fast deceleration and emergency stop.CN1: opto-isolated digital I/O terminal block with fixed factory preset signal definition due to F firmware lock, arbitrary reallocation of I/O functions is prohibited.CN2: dedicated connector exclusively for incremental encoder feedback cable.
6. PROTECTION FUNCTIONS
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-version preset parameters will not be erased 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 frequent braking working condition.
7. REPLACEMENT INSTRUCTION
CACR-SR10SB1AF cannot be directly substituted by SB-series SG general open-firmware model or other BB/BY/BZ variant drives due to different command input hardware and locked F firmware parameters. Only identical full part number CACR-SR10SB1AF supports plug-and-play replacement.
8. ROUTINE MAINTENANCE GUIDE
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 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 forbidden to avoid loss of factory preset matching parameters and machine malfunction.
9. COMMON FAULT TROUBLESHOOTING
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 during frequent fast deceleration can be solved 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 appears when actual mechanical load exceeds motor rated output, inspect stuck transmission mechanism or reduce machining cutting load accordingly.
