CACR stands for Yasnac VS800 full digital AC servo amplifier for CNC feed axis closed-loop motion control.SR supports three parameter configurable control modes: ±10VDC analog speed control, torque control and differential pulse position control.10 corresponds to 1.0kW matched servo motor with rated continuous output current 7.6Arms under 200V voltage class.BZ features upgraded feedback circuit plus standard built-in dynamic braking hardware; CN2 interface supports both incremental encoder and serial absolute encoder, different from BY series incremental-only circuit.1 defines power supply specification: three-phase AC200~230V main power plus independent single-phase AC200~230V separate control power supply.SS means single encoder feedback channel with factory preset fixed encoder matching parameters inside firmware.-Y367 is exclusive OEM customized marking for specific machine tool; factory preloads dedicated customized firmware, fixes CN1 I/O signal allocation and pre-calibrates loop gain parameters matching original equipment; core customized parameters are write-protected and full factory parameter reset is locked to avoid parameter loss.

Main input power: three-phase AC200V~230V, allowable voltage deviation -15%~+10%, compatible with 50Hz/60Hz industrial power grid. Control power needs independent single-phase AC200~230V individual wiring to isolate surge interference from main circuit.Continuous rated output current:7.6Arms; 150% overload continuous runtime 60 seconds, 300% peak instantaneous 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 adopted, maximum output frequency up to 300Hz; encoder resolution and matching data are locked by Y367 OEM program.

Operating ambient temperature:0℃~+55℃; storage temperature: -20℃~+70℃. Working environment 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 is mandatory for installation over 1000m elevation. Anti-vibration specification:10Hz~55Hz with 0.5mm single amplitude during continuous operation; net weight approx 3.1kg.

Speed adjustment ratio reaches 1:5000, full-load steady speed fluctuation controlled within ±0.01%. Built-in digital notch filter eliminates mechanical resonance and low-speed crawling during frequent start-stop cycles.Dual command input available: ±10VDC analog speed/torque signal and differential pulse position command; users can switch incremental/absolute encoder via minor auxiliary parameters, while core encoder matching settings are locked by Y367 custom firmware.Auto-tuning function partially restricted: complete full automatic motor parameter identification is disabled, only slight fine-tuning of partial gain parameters is permitted for minor on-site mechanical matching; all CN1 I/O definition is fixed by Y367 preset OEM logic and cannot be arbitrarily redefined through parameter modification.Onboard RS422 serial communication supports real-time running data reading and historical fault code inquiry; locked Y367 customized parameters cannot be revised or overwritten via communication port.

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 regenerative energy dissipation during repeated fast deceleration and emergency stop.CN1: opto-isolated digital I/O terminal block with fixed OEM signal definition under Y367 customization, user forbidden to change I/O function allocation freely.CN2: multi-purpose encoder feedback connector compatible with incremental or serial absolute encoder according to original machine’s matched motor configuration.

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 saves latest 10 groups of historical fault codes for maintenance inspection; Y367 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.

CACR-SR10BZ1SS-Y367 is exclusive OEM customized servo drive matched with designated CNC equipment and corresponding 1.0kW servo motor. Standard CACR-SR10BZ1SS without Y367 suffix cannot be directly substituted due to mismatched locked firmware and fixed I/O parameters; only identical full part number CACR-SR10BZ1SS-Y367 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 disassembling drive housing for maintenance to prevent electric shock hazard. Arbitrary full factory parameter reset is strictly prohibited to avoid loss of Y367 OEM customized data and subsequent 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 unauthorized modification of locked encoder parameters.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 Y367 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.
