CACR: Yasnac VS800 full digital AC servo amplifier for robot and automation equipment closed-loop motion control.SR: Three parameter-selectable 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 under AC200V input class.SZ: Robot-specific exclusive PCB and housing with dedicated internal circuit, different circuit design from SB/BB/BY standard CNC servo series.1: Power supply specification: three-phase AC200~230V main power plus independent single-phase AC200~230V separated control power supply.SS: Standard analog-only configuration; S means only ±10VDC analog speed/torque command input without differential pulse receiving hardware; the second S denotes standard factory default firmware without full parameter lock, most gain and I/O parameters are user adjustable.

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 can run 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 for frequent rapid deceleration and heavy-duty operation.IGBT sine-wave PWM modulation is adopted with maximum output frequency up to 300Hz.

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 frequent start-stop cycles.Single S-type hardware only accepts ±10VDC analog command without pulse input channel; position control function can be fully enabled and tuned via parameters.Complete automatic motor parameter auto-tuning is available; speed/position loop gains and CN1 I/O definitions can be freely modified and set by users via parameters, different from F locked version and Y-suffix OEM customized models.Onboard RS422 serial communication supports full parameter upload/download, real-time runtime data reading and historical fault record inquiry.

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 user configurable signal definition.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.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 is standard universal robot servo, can replace same-series SZ base hardware models after parameter reset and commissioning; cannot directly substitute SB series due to different internal hardware layout.

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. Full factory parameter reset is permitted for SS standard version.

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.Overload alarm triggers when actual mechanical load exceeds motor rated output; inspect stuck transmission mechanism or reduce processing load accordingly.
