CACR: Yasnac VS800 full digital AC servo amplifier for robot joint closed-loop motion control.SR: Three parameter-switchable control modes: ±10VDC analog speed control, torque control and parameter-enabled position control.10: Rated matching motor power 1.0kW, continuous rated output current 7.6Arms under AC200V input class.SZ: Robot-specified exclusive PCB and housing with dedicated internal circuit design, different from standard SB/BB/BY CNC servo series.1: Power supply specification: three-phase AC200~230V main power plus independent single-phase AC200~230V separated control power supply.SS: Base hardware only supports ±10VDC analog speed/torque command input without differential pulse receiving circuit; original SS is standard adjustable firmware.-Y217: Exclusive OEM customized suffix for specific robot equipment. Factory pre-sets loop gain parameters, fixes CN1 I/O logic and encoder matching data per original machine specification; all Y217 customized core parameters are permanently write-locked, full factory parameter initialization is prohibited.

Main input power: three-phase AC200V~230V, allowable 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 sustainable 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 for frequent rapid deceleration and heavy-duty robot cyclic operation.IGBT sine-wave PWM modulation is adopted with maximum output frequency up to 300Hz; encoder parameters are locked by Y217 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.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.

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 repeated start-stop of robot axes.SS hardware only accepts ±10VDC analog command without pulse input channel; position control function can be enabled via parameters but core position-related parameters are locked under Y217 OEM firmware.Auto-tuning function is partially restricted: full automatic motor parameter identification is disabled, only minor fine-tuning of auxiliary gain is available for slight on-site mechanical matching; CN1 I/O assignment follows fixed Y217 preset definition and cannot be arbitrarily modified.Onboard RS422 serial communication supports real-time runtime data reading and historical fault record inquiry; locked Y217 dedicated parameters cannot be revised via communication cable.

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 energy dissipation during frequent fast deceleration and robot emergency stop.CN1: opto-isolated digital I/O terminal block with fixed Y217 OEM exclusive signal definition, users cannot reassign I/O functions freely.CN2: dedicated connector exclusively for incremental encoder feedback cable.

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; Y217 preset parameters remain unchanged 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 and frequent emergency stop working conditions.

CACR-SR10SZ1SS-Y217 is OEM customized robot servo. Standard CACR-SR10SZ1SS without Y217 suffix cannot be directly substituted due to different locked parameters and fixed I/O logic; only identical full part number CACR-SR10SZ1SS-Y217 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 opening drive casing for maintenance to prevent electric shock hazard. Random full factory parameter reset is strictly forbidden to avoid loss of Y217 OEM customized data and abnormal robot running.

Overheat alarm mainly caused by radiator dust clogging, poor cabinet ventilation or long-term overloaded robot operation; 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 Y217 locked core parameters belongs to OEM firmware protection instead of hardware damage. Overload alarm triggers when actual mechanical load exceeds motor rated output; inspect robot transmission jamming or reduce working load accordingly.
