CACR: Yasnac VS800 full digital AC servo amplifier customized for robot axis closed-loop motion control.SR: Three parameter-switchable control modes: ±10VDC analog speed control, torque control and parameter-enabled position control.10: Rated matched motor power 1.0kW, continuous rated output current 7.6Arms for AC200V class input.SZ: Robot-specified exclusive PCB and housing with dedicated internal circuit, different from standard SB/BB/BY series hardware layout for robot application.1: Power specification: three-phase AC200~230V main power plus independent single-phase AC200~230V separated control power supply.S: Only ±10VDC analog speed/torque command input; no built-in differential pulse receiving hardware for pulse positioning signals.F: Base factory-locked firmware, core basic gain and encoder parameters preset and write-protected at factory.-Y90: Exclusive OEM customized marking for specific robot equipment; factory pre-sets servo loop gains, fixes CN1 I/O allocation and encoder matching parameters according to original machine requirement; all Y90 customized core parameters are permanently locked, full factory parameter reset is forbidden.

Main input: three-phase AC200V~230V, allowable voltage fluctuation -15%~+10%, compatible with 50Hz/60Hz industrial power grid. Control power needs separate single-phase AC200~230V independent wiring to isolate surge interference from main circuit.Continuous rated output current:7.6Arms; 150% overload continuous runtime 60 seconds, 300% instantaneous peak overload limited within 3 seconds during 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-load robot operation.IGBT sine-wave PWM modulation, maximum output frequency up to 300Hz; encoder parameters locked under Y90 customized program.

Operating ambient temperature:0℃~+55℃; storage temperature: -20℃~+70℃. Ambient humidity 5%~80%RH without condensation; protection grade IP20, vertical upright installation inside electrical cabinet required.Full-load operation below 1000m altitude; load derating is required for installation above 1000m elevation. Vibration resistance:10Hz~55Hz with 0.5mm single amplitude; net weight approx 3.0kg.

Speed regulation ratio reaches 1:5000, full-load steady speed deviation ≤±0.01%. Built-in digital notch filter restrains mechanical resonance and low-speed crawling during repeated start-stop of robot axes.S-type hardware only supports ±10VDC analog command without pulse input circuit; position control can be activated via parameters but core relevant parameters are locked by Y90 customized firmware.Auto-tuning is partially restricted: full automatic motor parameter identification is disabled, only slight fine adjustment of auxiliary gain is available for field mechanical matching; CN1 I/O definition is fixed to Y90 robot OEM preset logic and cannot be revised arbitrarily via parameters.Onboard RS422 serial communication supports real-time running data reading and historical fault record query; locked Y90 customized parameters cannot be modified 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 frequent fast deceleration and emergency stop of robot joints.CN1: opto-isolated digital I/O terminal block with fixed Y90 exclusive OEM signal definition; users cannot change I/O function assignment freely.CN2: dedicated connector for incremental encoder feedback cable.

Complete built-in protection items: overcurrent, DC bus overvoltage/undervoltage, drive overheat, encoder disconnection and motor overload protection. The drive automatically saves the latest 10 groups of fault history codes; Y90 preset parameters remain unchanged after power cut or fault reset.Internal standard dynamic braking circuit handles regular deceleration energy consumption; external regenerative resistor must be installed between P and BN terminals under long-term heavy-load and frequent emergency stop conditions.

CACR-SR10SZ1SF-Y90 is special robot OEM customized unit with unique SZ hardware and Y90 locked parameters. Standard CACR-SR10SZ1SF without Y90 suffix or conventional SB-series servo cannot be directly replaced; only identical full part number CACR-SR10SZ1SF-Y90 supports plug-and-play replacement.

Check tightness of power cables, motor wire and CN1/CN2 connectors before each startup to avoid poor-contact faults. Clean radiator dust every 3~6 months to maintain heat dissipation and prevent overheat alarm.Cut all AC power and wait over 15 minutes for full discharge of internal DC bus capacitor before opening drive casing for maintenance to avoid electric shock. Random full factory parameter reset is strictly prohibited to prevent loss of Y90 customized data and abnormal robot operation.

Overheat alarm: radiator dust accumulation, poor cabinet ventilation or continuous overloaded robot running.Encoder fault: loose CN2 connector or damaged feedback cable.Overvoltage during frequent fast deceleration: mount external regenerative resistor between P and BN terminals.Failure to write locked parameters is OEM firmware protection instead of hardware breakdown.Overload alarm: mechanical jamming of robot transmission structure or excessive working load.
