CACR: Yasnac VS800 full digital AC servo amplifier for closed-loop feed axis control on CNC machine tools.SR: Supports three parameter-selectable control modes: ±10VDC analog speed control, torque control and differential pulse position control.10: Rated matched motor power 1.0kW; rated continuous output current 7.6Arms under AC200V input class.BZ: Upgraded feedback circuit layout with standard built-in dynamic braking circuit; CN2 hardware supports both incremental encoder and serial absolute encoder feedback, different from BY incremental-only hardware.1: Power supply specification: three-phase AC200~230V main power plus independent single-phase AC200~230V separated control power supply.SS: Single encoder channel hardware with fixed factory-specified encoder matching parameters preset inside firmware.-Y142: Exclusive OEM customized version for dedicated CNC equipment; factory pre-calibrates servo loop gains and fixes CN1 I/O signal definition; core functional parameters are write-protected, full factory parameter initialization function is locked and prohibited.

Main input: three-phase AC200V~230V with permissible voltage fluctuation -15%~+10%, compatible with 50Hz/60Hz industrial mains. Control power requires separate single-phase AC200~230V independent wiring to avoid surge interference from main power 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 heavy-load rapid deceleration.IGBT sine-wave PWM modulation, maximum output frequency up to 300Hz; encoder resolution data is locked by Y142 customized program.

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.Maximum applicable installation altitude below 1000m above sea level; continuous load derating needed for installation over 1000m elevation. Anti-vibration standard:10Hz~55Hz with 0.5mm single amplitude during stable operation; net weight approx 3.1kg.

Speed adjustment ratio reaches 1:5000, full-load steady speed deviation ≤±0.01%. Built-in digital notch filter suppresses mechanical resonance and low-speed crawling during frequent start-stop cycles.Dual command input available: ±10VDC analog speed/torque signal and differential pulse position signal; CN2 port can switch between incremental and absolute encoder only within limited parameter range locked by Y142.Auto-tuning function partially restricted by Y142 OEM program: full automatic motor parameter identification is disabled, only tiny fine adjustment of partial auxiliary gain is allowed for minor on-site mechanical matching; all CN1 I/O assignment is fixed by factory preset OEM logic and cannot be redefined via parameter modification.Onboard RS422 serial communication supports real-time operating data reading and historical fault record inquiry; all locked Y142 customized parameters cannot be edited or overwritten via communication line.

R/S/T: three-phase main AC power input terminals; U/V/W: three-phase output terminals connected to 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 OEM-defined signal layout under Y142 customization, user cannot alter I/O functions arbitrarily.CN2: universal encoder feedback connector compatible with incremental or serial absolute encoder as per original machine factory configuration.

Complete protection items: overcurrent protection, DC bus overvoltage/undervoltage protection, drive overheat protection, encoder cable breakage protection and motor overload protection. The drive automatically stores latest 10 groups of historical fault codes; Y142 OEM preset parameters remain intact after power cut or fault reset.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 frequent emergency stop operation.

CACR-SR10BZ1SS-Y142 is dedicated OEM customized servo drive; standard CACR-SR10BZ1SS without Y142 suffix cannot substitute directly due to mismatched locked parameters and fixed I/O logic. Only identical full part number CACR-SR10BZ1SS-Y142 realizes plug-and-play replacement.

Check tightness of power cables, motor cable and CN1/CN2 connectors before each startup to avoid poor-contact induced alarms; clean radiator dust every 3~6 months to ensure heat dissipation and prevent overheat shutdown.Cut all AC power and wait minimum 15 minutes for internal DC bus capacitor full discharge before opening drive casing for maintenance to avoid electric shock hazard. Random full factory parameter reset is strictly forbidden to prevent loss of Y142 customized machine parameters and equipment malfunction.

Overheat alarm mainly caused by radiator dust clogging, poor cabinet ventilation or long-term overloaded running; encoder fault arises from loose CN2 connector, damaged feedback cable or unauthorized modification of locked encoder parameters.Overvoltage during frequent rapid deceleration can be solved by mounting external regenerative resistor between P and BN terminals; parameter write failure when modifying Y142 locked parameters is OEM firmware protection instead of hardware fault; overload alarm occurs when actual mechanical load exceeds motor rated output, inspect transmission jamming or reduce machining load accordingly.
