1. MODEL CODE DEFINITION
CACR: Yasnac VS800 full digital AC servo amplifier for CNC and automated industrial equipment.SR: Dual control modes including ±10VDC analog speed/torque control and differential line-driver pulse position control, switchable via internal parameters.12: Rated power 1.2kW, AC200V grade, continuous rated output current: 11.7Arms.T: OEM customized exclusive main PCB circuit design, different from standard TB universal series board.Z: Fixed CN1 I/O signal assignment; core application parameters locked by original factory firmware.6: Preloaded No.6 fixed factory parameter set with matched partial peripheral circuit setting.SM: Customized dedicated encoder circuit exclusively matched to specified SM-type servo motor with unique CN2 pin definition.-E: Export version designed in compliance with international IEC safety specification, overseas customized firmware and safety component configuration, different from domestic non-E standard CACR-SR12TZ6SM.
2. ELECTRICAL SPECIFICATIONS
Main input power: 3-phase AC200V~230V, allowable voltage deviation -15%~+10%, 50/60Hz.Overload specification: 150% rated current continuous operation for 60 seconds; 300% instantaneous peak overload limited within 3 seconds during motor startup.Nominal DC bus voltage: DC280V~DC320V; terminals P and BN are reserved for external regenerative braking resistor connection.Modulation mode: IGBT sine-wave PWM modulation, maximum output frequency 300Hz.Net weight approx 3.6kg, IP20 protection grade for vertical cabinet installation only.
3. INSTALLATION & ENVIRONMENT REQUIREMENT
Operating ambient temperature: 0℃ ~ +55℃; storage temperature: -20℃ ~ +70℃.Working humidity: 5%~80%RH without condensation. Output power derating is required when installation altitude exceeds 1000 meters above sea level.Vibration resistance: 10~55Hz, single amplitude 0.5mm, meets international export equipment environmental standard.
4. CONTROL PERFORMANCE AND FEATURES
Speed adjustment ratio reaches 1:5000, full-load speed fluctuation ≤±0.01%. Built-in digital notch filter suppresses mechanical resonance and low-speed crawling under frequent start-stop cycles.Dual command input supports free switching between ±10VDC analog command and differential pulse position command via parameter modification.SM+Z+E customized restriction: Only partial loop gain parameters can be adjusted on site; OEM core parameters are permanently write-locked by firmware. Full factory parameter initialization is strictly forbidden to avoid abnormal equipment operation or motor runaway.Onboard RS422 communication adopts exclusive export-version protocol inconsistent with domestic model; real-time running data and latest 10 groups of fault records can be checked, while locked customized parameters cannot be revised through communication cable.
5. TERMINAL & CONNECTOR DESCRIPTION
R/S/T: Three-phase main AC power input terminals; U/V/W: Three-phase servo motor power output terminals.P/BN: External regenerative braking resistor wiring terminals for energy dissipation during rapid deceleration and emergency stop.CN1: Opto-isolated digital I/O terminal block with fixed OEM preset signal definition due to Z and E customization, most I/O assignments cannot be changed by parameters.CN2: Exclusive SM export-type encoder connector with dedicated pin layout, only compatible with designated SM-series servo motor.Front panel 7-segment LED displays real-time operating status and fault codes.
6. INTEGRATED PROTECTION FUNCTIONS
Complete protection items: overcurrent protection, DC bus overvoltage/undervoltage protection, drive overheat protection, encoder disconnection protection, motor overload protection and CPU abnormal operation protection.The drive automatically stores last 10 fault codes without data loss after power cut or fault reset; original factory customized parameters remain unchanged after reset operation.Internal dynamic braking circuit is integrated for regular deceleration energy consumption; external regenerative resistor must be installed between P and BN terminals under long-term heavy cyclic load and frequent emergency stop working conditions.
7. REPLACEMENT GUIDELINE
CACR-SR12TZ6SM-E is dedicated export customized servo unit. Domestic CACR-SR12TZ6SM without -E suffix or other TZ/TB series standard drives cannot be directly substituted, caused by different safety circuit, encoder definition and locked OEM parameters. Only identical full part number CACR-SR12TZ6SM-E supports plug-and-play replacement.
8. ROUTINE MAINTENANCE INSTRUCTION
Check tightness of power cables, CN1 and CN2 connectors before every startup to eliminate poor-contact induced faults. Clean radiator cooling fin dust every 3~6 months to guarantee heat dissipation and prevent overheat shutdown.Cut off all AC power supply and wait more than 15 minutes for full discharge of internal DC bus capacitor before opening drive cover for maintenance to avoid electric shock hazard. Never perform full factory parameter reset on site.
9. COMMON FAULT TROUBLESHOOTING
Overheat alarm: Blocked radiator dust, poor cabinet ventilation or continuous overload → clean cooling structure or reduce operating load.Encoder error alarm: Loose CN2 connector, damaged feedback cable or mismatched SM dedicated motor → inspect wiring and matching motor model.Overvoltage alarm during quick deceleration: Install external regenerative resistor between P and BN terminals.Parameter write failure: Trying to modify firmware-locked OEM core parameters, this belongs to normal software protection instead of hardware failure.Overload alarm: Mechanical transmission jamming or excessive working load → check mechanical structure and cut down load accordingly.
