2. ELECTRICAL SPECIFICATIONS
Main circuit input: 3-phase AC200~230V, tolerance -15%~+10%, compatible with 50/60Hz industrial mains; control power must use separate single-phase AC200~230V independent wiring to isolate power surge interferenceContinuous rated output:7.6Arms; 150% overload sustainable for 60s, 300% peak instantaneous overload limited within 3s for motor acceleration start; normal DC bus voltage DC280~320V, terminals P-BN reserved for external regenerative resistor wiring under frequent high-speed deceleration and heavy cutting loadIGBT sine-wave PWM drive, maximum output frequency 300Hz; built-in bus overvoltage suppression circuit to restrain voltage spike during dynamic braking.
3. INSTALLATION & AMBIENT REQUIREMENT
Operating temperature:0℃~+55℃; storage ambient -20℃~+70℃; working humidity 5%~80%RH without dew; IP20 protection grade, mandatory vertical upright installation inside electric cabinetValid installation altitude below 1000m; continuous output derating needed when mounted above 1000m elevation; anti-vibration standard 10~55Hz with 0.5mm single amplitude; net weight around 3.1kg
4. CONTROL FEATURE & LIMITATION OF Y72 CUSTOM VERSION
Speed adjustment ratio up to 1:5000, full load speed fluctuation ≤±0.01%; onboard digital notch filter eliminates mechanical resonance and low-speed crawling during frequent start-stopAccept dual command input: ±10VDC analog speed/torque signal and line-driver differential pulse position signal; dual encoder function free switching between incremental/absolute via CN2 parameter settingG firmware allows full auto motor parameter identification for standard 1kW Yasnac motor; core loop gains adjustable by user; Y72 customized restriction: CN1 digital I/O signal definition fixed by OEM preset program, most I/O function parameters write-locked, user cannot arbitrarily redefine input/output assignment unlike standard -E export modelOnboard RS422 serial communication supports parameter upload/download for unlocked items, real-time running data reading and historical fault record query; locked OEM parameters of Y72 cannot be modified or overwritten via communication.
5. TERMINAL & CONNECTOR DESCRIPTION
R/S/T: Three-phase main AC power input terminals; U/V/W: Three-phase output connecting servo motor stator cable; P/BN: External regenerative brake resistor connecting terminals for heavy-load frequent emergency stop scenarioCN1: Opto-isolated digital I/O terminal block with fixed OEM-defined signal logic due to Y72 customization; user forbidden to change default I/O function via parametersCN2: Dual-type encoder feedback connector matching 2-suffix dual-encoder hardware, applicable for incremental or serial absolute encoder wiring as per original machine configuration.
6. FULL PROTECTION FUNCTIONS
Complete built-in protection: overcurrent, DC bus over/undervoltage, drive overheat, encoder cable break, motor overload stall, main power phase loss protectionSmall built-in dynamic braking resistor for regular deceleration energy consumption; external regenerative resistor must be installed between P-BN under long-time repeated rapid braking; drive stores latest 10 groups fault codes for maintenance check; Y72 factory preset OEM parameters keep intact after power failure or fault reset.
7. REPLACEMENT NOTE (KEY FOR Y72)
CACR-SR10BE12G-Y72 is dedicated OEM customized drive, cannot directly replaced by ordinary CACR-SR10BE12G or -E standard model: Y72 has locked fixed I/O program and factory pre-set machine matching parameters, ordinary general drive needs full parameter rewrite and I/O logic modification before replacement; only identical full part number CACR-SR10BE12G-Y72 supports plug-and-play substitution.
8. DAILY MAINTENANCE RULES
Check tightness of R/S/T, U/V/W power wiring and CN1/CN2 plugs before startup to avoid poor contact induced alarms; clean radiator fin dust every 3~6 months to guarantee heat dissipation and prevent overheat shutdownCut all AC power and wait minimum 15 minutes for internal DC capacitor full discharge before opening casing maintenance to avoid electric shock; backup all adjustable user parameters before factory reset, random full parameter reset will restore Y72 OEM locked default setting and cause machine abnormal operation.
9. COMMON FAULT TROUBLESHOOTING
Overheat alarm: radiator dust blockage, cabinet poor ventilation or long-term overloaded running; encoder fault: loose CN2 connector, damaged feedback cable or mismatched encoder type against original Y72 machine settingOvervoltage during frequent fast deceleration: fit external regenerative resistor on P-BN terminals; parameter writing failure: user tries to modify Y72 OEM locked I/O and customized function parameters (firmware protection instead of hardware fault); overload alarm: mechanical transmission jamming or excess cutting load, inspect mechanical blocking status accordingly.
