2. ELECTRICAL SPECIFICATIONS
Main power input: 3-phase AC200V~230V, allowable voltage fluctuation -15%~+10%, compatible with 50Hz/60Hz industrial mains; control power needs standalone single-phase AC200~230V separate wiring to isolate main circuit surge interference.Continuous rated output current:7.6Arms; 150% overload sustainable for 60s, 300% peak instantaneous overload limited within 3s for motor startup acceleration. Normal DC bus operating voltage DC280V~DC320V; terminals P and BN reserved for external regenerative braking resistor connection under frequent rapid deceleration and heavy-duty cutting condition.IGBT sine-wave PWM modulation structure, maximum output frequency 300Hz, built-in semi-active damping circuit to reduce DC bus voltage spike during dynamic braking.
3. INSTALLATION & AMBIENT REQUIREMENTS
Working ambient temperature range:0℃~+55℃; storage temperature -20℃~+70℃; operating environment relative humidity 5%~80%RH with no dew condensation; enclosure protection grade IP20, vertical upright mounting inside electrical cabinet is mandatory.Rated applicable altitude below 1000m above sea level; continuous running power derating required for installation over 1000m elevation. Vibration resistance:10~55Hz, 0.5mm single amplitude under stable operation; net unit weight approx 3.2kg.
4. CONTROL PERFORMANCE & FUNCTION CONFIGURATION
Speed adjustment ratio reaches 1:5000, full-load steady-state speed deviation ≤±0.01%; onboard digital notch filter suppresses mechanical resonance and low-speed crawling during frequent start-stop cycles.Dual command receiving function: supports ±10VDC analog speed/torque signal and differential line-driver pulse position command input; 2 suffix enables dual encoder selection via parameters, switchable between standard incremental and optional serial feedback signal at CN2 port.F firmware locks partial core gain parameters but retains adjustable range for position/speed loop basic gain; full auto motor parameter identification available for standard matching 1.0kW Yasnac servo motor, partial advanced auto-tune functions locked by factory setting; -E export version cancels OEM fixed I/O logic restriction, most CN1 signal assignments editable by user parameters.
5. TERMINAL & CONNECTOR DESCRIPTION
R/S/T: three-phase main AC power input terminals; U/V/W: three-phase power output connecting servo motor stator cable; P/BN: external regenerative brake resistor wiring terminals for extra energy dissipation at high-frequency deceleration.CN1: opto-isolated digital I/O terminal block with 8 input points and 6 relay output points; -E standard version allows free redefinition of input/output function by internal parameters instead of fixed OEM definition.CN2: dual-purpose encoder feedback connector supporting two types of motor encoder wiring corresponding to 2 suffix specification; onboard RS422 serial communication port follows Yaskawa proprietary protocol, supports real-time runtime data reading, historical fault record inquiry, and editable non-locked parameter download/upload via upper computer.
6. FULL PROTECTION FUNCTION LIST
Complete built-in protection functions: overcurrent protection, DC bus overvoltage/undervoltage protection, drive overheat protection, encoder disconnection fault protection, motor overload and stall protection, main circuit power phase loss protection.Internal standard dynamic braking resistor embedded for regular deceleration energy absorption; external regenerative resistor must be fitted between P-BN under long-time heavy load and repeated emergency stop application. Drive automatically stores latest 10 groups of historical fault codes for maintenance troubleshooting; F-version locked parameters will not be cleared after power failure or fault reset operation.
7. REPLACEMENT GUIDANCE
CACR-SR10BE12F-E is universal export standard model, same-spec non-E suffix CACR-SR10BE12F can be substituted after parameter reset and manual gain setting; customized Y-suffix variants cannot directly replace this model due to fixed locked OEM firmware and I/O definition mismatch. Direct plug-and-play requires identical full part number CACR-SR10BE12F-E.
8. DAILY MAINTENANCE RULES
Check tightness of R/S/T, U/V/W power wiring and CN2/CN1 plug connection before every equipment startup to eliminate poor-contact induced alarm; clean radiator fin dust every 3~6 months to guarantee heat dissipation and avoid overheat shutdown.Cut all AC power supply and wait minimum 15 minutes for internal DC bus capacitor full discharge before disassembling drive casing for maintenance to prevent electric shock hazard. Stop continuous operation when cabinet inner ambient temperature exceeds 55℃; random full factory parameter reset is not recommended to avoid losing pre-set matching parameters of onsite mechanical system.
9. COMMON FAULT DIAGNOSIS
Overheat alarm mostly caused by radiator clogging dust, poor cabinet air circulation or long-term overloaded running; encoder fault mainly triggered by loose CN2 connector, damaged feedback cable or wrong encoder type selected against 2-suffix dual setting standard.Overvoltage alarm during frequent fast deceleration resolves by installing external regenerative resistor on P-BN terminals; parameter write failure occurs only when modifying F-version factory-locked core parameters, belonging to firmware protection instead of drive hardware failure; overload alarm appears when actual mechanical load exceeds motor rated output, inspect transmission stuck fault or reduce machining cutting load accordingly.
