CACR stands for Yasnac VS800 full digital AC Servopack series developed for CNC machine feed axis closed-loop motion control.SR: Three switchable control modes including pulse position control, ±10VDC analog speed control and analog torque control via internal parameter setup.10: Matched rated servo motor power 1.0kW, rated continuous output current 5.3Arms.BB: Standard main control PCB and standard metal cabinet without original factory hardware modification.1: AC200V grade specification; three-phase main power input plus independent single-phase separated control power supply.E: Factory fixed parameter setting for 2000PPR incremental encoder, specially matched with Yaskawa M-series AC servo motor;S: Dual command input circuit supporting differential pulse position instruction and ±10VDC analog speed instruction switching by parameter setup.Y17: OEM exclusive customized suffix for dedicated CNC machining center/vertical milling machine: Pre-programmed locked OEM firmware, fixed CN1 I/O signal allocation and factory pre-tuned servo gain parameters matched to original machine structure; core critical control parameters are write-protected, full factory parameter reset function is disabled to avoid loss of original machine preset data, customized for fixed-brand vertical machining equipment feed axis application.

Main circuit input: Three-phase AC200V~230V, permissible voltage fluctuation range -15%~+10%, compatible with 50Hz/60Hz industrial grid voltage. Control power needs independent single-phase AC200V~230V wiring to isolate interference from main power circuit.Rated continuous output current 5.3Arms; 150% overload operation sustainable for 60 seconds, 300% instantaneous peak overload limited within 3 seconds for rapid acceleration. DC bus normal working voltage DC280V~DC320V; terminals P and BN reserved for external regenerative braking resistor wiring under frequent heavy-load rapid deceleration working conditions.Adopts IGBT sine-wave PWM modulation design, maximum output frequency reaches 300Hz; Y17 customized firmware permanently locks encoder resolution at 2000PPR, any unauthorized modification on encoder setup parameters will trigger encoder mismatch protection alarm immediately.

Operating ambient temperature: 0℃ ~ +55℃; storage ambient temperature: -20℃ ~ +70℃. Working environment humidity 5%~80%RH without dew condensation; enclosure protection grade IP20, must be vertically installed inside electrical control cabinet.Maximum allowable installation altitude ≤1000m above sea level; derated load operation is required when mounting height exceeds 1000m. Vibration resistance standard: 10Hz~55Hz with 0.5mm single amplitude during continuous running; net weight approximately 2.35kg.

Speed adjustment ratio up to 1:5000, full-load steady-state speed deviation controlled within ±0.01%. Built-in digital notch filter effectively suppresses mechanical resonance and low-speed crawling during frequent start-stop cycles.Dual command input function allows users to switch command source between differential pulse position signal and analog speed signal via adjustable non-locked auxiliary parameters; three core control modes can also be switched within editable parameter range.Auto-tuning function is partially restricted by Y17 OEM customized program: full automatic motor parameter identification function is locked and unavailable, only minor gain fine-tuning parameters can be modified for on-site mechanical matching; CN2 feedback connector is fixed exclusively for 2000PPR incremental encoder of matched 1.0kW M-series servo motor.

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 regenerative energy consumption during quick deceleration.CN1: Optocoupler isolated digital I/O terminal block with 8-channel input and 6-channel relay output; all I/O signal definition pre-configured by Y17 OEM firmware matching original CNC system, most signal assignment cannot be redefined by parameter modification arbitrarily.CN2: Dedicated connector for incremental encoder feedback cable fixed for 2000PPR PG; onboard RS422 serial port follows Yaskawa private communication protocol, supports real-time operating data reading and historical fault record inquiry, locked core parameters cannot be revised or written via serial communication line.

Built-in standard dynamic braking circuit handles regenerative energy dissipation under regular deceleration; external regenerative resistor must be installed between P and BN terminals for heavy cutting and repeated emergency stop working scenarios. Independent high-speed and low-speed gain groups pre-calibrated by Y17 factory program to match original machine dynamic characteristics.Complete protection functions include overcurrent protection, DC bus overvoltage/undervoltage protection, drive overheat protection, encoder wire breakage protection and motor overload protection. The servo drive automatically stores latest 10 groups of historical fault codes for maintenance check; Y17 OEM preset parameters will not be erased after power-off or fault reset operation.

CACR-SR10BB1ES-Y17 is OEM custom servo driver exclusively matched with designated vertical machining center and corresponding 1.0kW M-series 2000PPR servo motor. Standard CACR-SR10BB1ES without Y17 suffix cannot be used for direct replacement; mismatched locked firmware and factory preset parameters will lead to positioning drift, abnormal rotating speed or recurring system alarms. Replacement needs identical full part number CACR-SR10BB1ES-Y17 to realize plug-and-run installation.

Check fastening condition of power cables, motor cable and CN2 encoder plug before every equipment startup to eliminate poor-contact induced malfunction. Clean radiator fin dust every 3~6 months to guarantee effective heat dissipation 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. Stop long-time continuous operation once inner cabinet temperature exceeds 55℃. Never execute full parameter factory reset randomly; improper reset will erase Y17 OEM preset data and cause machine abnormal failure.

Overheat alarm mainly caused by radiator dust blockage, poor cabinet ventilation or long-term overloaded running. Encoder fault alarm mostly generated by loose CN2 connector, damaged feedback cable or illegal modification on fixed 2000PPR encoder parameters under firmware lock.Overvoltage alarm occurs during frequent heavy-load rapid deceleration; solve the problem by mounting external regenerative braking resistor between P and BN terminals. Parameter write failure when modifying Y17 locked core parameters belongs to normal OEM anti-tamper protection instead of drive hardware damage. Overload alarm triggers when actual mechanical load exceeds motor rated output; check blocked transmission structure or reduce processing load accordingly.
