CACR-SR12TZ6SF
Description
1. MODEL CODE EXPLANATION
2. ELECTRICAL SPECIFICATION
Input Power: 3-phase AC200~230V, allowable fluctuation -15%~+10%, 50/60Hz industrial frequency
Output characteristic: 150% rated current sustainable for 60s; 300% instantaneous peak overload within 3s startup
DC bus nominal voltage: DC280V~DC320V; terminals P & BN reserved for external regenerative braking resistor connection for frequent rapid deceleration/emergency stop
Drive modulation: IGBT sine-wave PWM, maximum output frequency 300Hz; unit net weight ≈3.6kg, IP20 cabinet vertical installation only
3. INSTALLATION & ENVIRONMENT REQUIREMENT
Operating ambient temp: 0℃~+55℃; storage temp: -20℃~+70℃
Working humidity: 5%~80%RH, no condensation allowed; install inside closed electrical cabinet
Altitude derate: reduce rated output power when installation height over 1000m above sea level
Anti-vibration standard: 10~55Hz, single amplitude 0.5mm
4. CONTROL PERFORMANCE & FUNCTION
Speed adjustable ratio up to 1:5000, full-load speed fluctuation ≤±0.01%, built-in digital notch filter for mechanical resonance suppression
Dual command input: analog ±10VDC speed command + differential pulse position command, mode switched by parameter setting
SF customized limit: Partial motor auto-tuning available; OEM core parameters write-protected, only general gain parameters editable; full factory parameter reset is forbidden (will trigger machine abnormal running)
Onboard RS422 communication port: real-time running data monitoring, check latest 10 groups fault history; locked SF customized parameters cannot be modified via communication cable
5. TERMINAL & CONNECTOR DEFINITION
R/S/T: Three-phase main AC power input terminals; U/V/W: Servo motor three-phase power output terminals
P/BN: External regenerative brake resistor connection terminals
CN1: Opto-isolated digital I/O terminal block, fixed Z+SF OEM signal assignment, most IO definition non-modifiable by parameters
CN2: Exclusive SF customized incremental encoder connector, wiring differs from standard A/B phase encoder definition, matched designated F-type servo motor only
Front panel 7-segment LED: real-time running status + fault code display
6. FULL PROTECTION FUNCTION LIST
Fault data storage: last 10 fault codes saved permanently, not cleared after power off or fault reset; SF preset OEM parameters remain unchanged after reset
Internal dynamic brake circuit integrated for normal deceleration; external regenerative resistor must be fitted between P-BN for heavy-duty cyclic operation and frequent emergency stop
7. REPLACEMENT INSTRUCTION
CN2 encoder circuit is SF dedicated design, mismatched drive will cause encoder alarm or motor runaway
Z+6+SF locked factory application parameters, universal standard drive reset leads to equipment malfunction
Only identical part number CACR-SR12TZ6SF supports plug-and-play replacement
8. ROUTINE MAINTENANCE REGULATION
Pre-power-on inspection: fasten RST/UVW power cables, CN1/CN2 connector terminals to eliminate poor contact failure
Clean radiator cooling fin dust every 3~6 months to avoid overheat shutdown caused by poor heat dissipation
Cut all AC input power and wait ≥15 minutes for internal DC bus capacitor full discharge before opening drive cover for maintenance (prevent electric shock hazard)
Strictly prohibit full parameter factory initialization operation on site
9. COMMON FAULT DIAGNOSIS
Overheat Alarm: radiator dust blocking / cabinet ventilation poor / continuous overloaded → clean cooling system or reduce operating load
Encoder Fault Alarm: loose CN2 plug / damaged feedback cable / mismatched SF dedicated motor → check wiring and motor model matching
Overvoltage during rapid deceleration: add external braking resistor between P & BN terminals
Parameter Write Failure: trying to modify Z/SF locked OEM core parameters (firmware lock, no hardware breakdown)
Overload Alarm: mechanical transmission stuck / excessive load → inspect mechanical structure and cut down load
