1. MODEL CODE DEFINITION
CACR stands for Yasnac VS800 full digital AC servo amplifier for 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 matched motor power 1.0kW with continuous rated output current 7.6Arms under AC200V input grade.SB refers to exclusive compact PCB layout and housing structure equipped with standard built-in dynamic braking circuit, differing from BB/BY/BZ internal circuit design.1 defines power supply specification: three-phase AC200~230V main power plus independent single-phase AC200~230V separated control power supply.A means only ±10VDC analog speed/torque command input; no onboard differential pulse receiving hardware for pulse positioning control.F is factory-locked firmware with core loop gain, encoder and partial I/O parameters pre-set and write-protected by factory.-Y100 is dedicated OEM customized suffix for specific machine tool; factory pre-calibrates servo parameters and fixes CN1 I/O logic matching original equipment, customized key parameters are permanently locked and full factory parameter reset is prohibited.
2. ELECTRICAL SPECIFICATIONS
Main input power: three-phase AC200V~230V, allowable voltage fluctuation -15%~+10%, compatible with 50Hz/60Hz industrial power grid. Control power needs independent single-phase AC200~230V separate wiring to isolate surge interference from main circuit.Continuous rated output current:7.6Arms; 150% overload runs 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.IGBT sine-wave PWM modulation is adopted with maximum output frequency up to 300Hz; encoder matching parameters are locked by Y100 OEM 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 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.
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.Only ±10VDC analog command input is available due to A-type hardware without pulse input channel; position function can be enabled via parameter setting while relevant core position parameters are locked by Y100 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 is fixed by Y100 preset OEM logic and cannot be arbitrarily redefined via parameters.Onboard RS422 serial communication supports real-time runtime data reading and historical fault record inquiry; locked Y100 customized parameters cannot be modified through communication cable.
5. TERMINAL & CONNECTOR DESCRIPTION
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 OEM signal definition under Y100 customization, users are forbidden to alter I/O function allocation freely.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; Y100 OEM preset parameters will not be cleared 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.
7. REPLACEMENT INSTRUCTION
CACR-SR10SB1AF-Y100 is exclusive OEM customized servo drive matched with designated CNC equipment and corresponding 1.0kW incremental encoder servo motor. Standard CACR-SR10SB1AF without Y100 suffix cannot be directly substituted due to mismatched locked customized parameters and fixed I/O definition; only identical full part number CACR-SR10SB1AF-Y100 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 off all AC power supply and wait over 15 minutes for internal DC bus capacitor full discharge before disassembling drive housing for maintenance to prevent electric shock hazard. Random full factory parameter reset is strictly prohibited to avoid loss of Y100 OEM customized data and subsequent 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 occurs during frequent heavy-load rapid deceleration; resolve by installing external regenerative resistor between P and BN terminals. Parameter write failure when modifying Y100 locked core parameters belongs to normal OEM 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.
