Description

1. MODEL CODE DEFINITION

CACR: Yasnac VS800 full-digital AC Servopack for CNC machine dedicated drive
SR: Multi-mode control: ±10VDC analog speed/torque + differential pulse position control (parameter switchable)
12: Rated power 1.2kW, AC200V grade, continuous output current:11.7Arms
T: Special customized PCB layout for dedicated CNC equipment (non-standard universal mainboard)
Z: OEM customized control circuit, fixed factory I/O definition, partial core parameters write-locked by firmware
0: Firmware version No.0, preset fixed machine default parameters at factory, no universal standard factory setting
SM: Special motor matching + customized encoder interface; exclusive OEM program for specific machine manufacturer

2. MAIN ELECTRICAL SPECIFICATIONS

  • Input Power: 3-phase AC200V~230V, tolerance -15%~+10%, 50/60Hz industrial frequency

  • Rated Output: 11.7Arms continuous; 150% overload sustainable for 60s; 300% peak overload within 3s startup limit

  • DC Bus Voltage: DC280V~DC320V; terminals P & BN for external regenerative braking resistor connection

  • Modulation: IGBT sine-wave PWM, max output frequency 300Hz

  • Weight: Approx 3.6kg, IP20 cabinet-mounted design

3. AMBIENT & INSTALLATION REQUIREMENT

  • Operating Temp: 0℃ ~ +55℃; Storage Temp: -20℃ ~ +70℃

  • Humidity: 5%~80%RH non-condensation; install vertically inside electrical cabinet

  • Altitude: ≤1000m; derate output power above 1000m elevation

  • Vibration resistance:10~55Hz, single amplitude 0.5mm

4. CONTROL FEATURES & PERFORMANCE

  1. Speed range ratio 1:5000, full-load speed fluctuation ≤±0.01%, built-in digital notch filter to eliminate mechanical resonance

  2. Dual command input: analog ±10VDC + line-driver differential pulse input, switch control mode via internal constants

  3. SM customized limit: Partial auto-tuning available; core OEM parameters locked (cannot modify freely); only common gain parameters editable; full factory parameter reset is forbidden (will cause machine malfunction)

  4. Onboard RS422 communication: monitor running data, read fault history; locked OEM parameters cannot be revised via communication cable

5. TERMINAL & CONNECTOR DEFINITION

  • R/S/T: 3-phase main AC power input; U/V/W: servo motor 3-phase power output

  • P/BN: External braking resistor terminals for high-frequency rapid deceleration

  • CN1: Optocoupler isolated digital I/O terminal block, Z+SM fixed OEM signal assignment, most I/O definition cannot be modified by parameters

  • CN2: Dedicated customized encoder connector matching OEM specified servo motor (different from standard A-type encoder wiring)

  • Front 7-segment LED: real-time operating status + fault code display

6. FULL PROTECTION FUNCTION LIST

Overcurrent / DC bus overvoltage/undervoltage / drive overheat / encoder break / motor overload / CPU operation error protection
  • Stores latest 10 groups historical fault codes; fault records clearable manually, but OEM preset parameters keep unchanged after reset/power off

  • Built-in internal dynamic brake; add external regenerative resistor on P-BN for heavy cyclic load & frequent emergency stop

7. REPLACEMENT INSTRUCTION

CACR-SR12TZ0SM is unique OEM customized model, cannot be directly replaced by standard CACR-SR12TB6AF/CACR-SR12TB6CSE:
  • Different CN2 encoder circuit, fixed SM matching motor specification; mismatched drive leads to encoder alarm or runaway

  • Locked Z-type factory parameters, universal drive reset will lose OEM machine program

  • Only identical part number CACR-SR12TZ0SM supports plug-and-play replacement

8. ROUTINE MAINTENANCE RULES

  1. Pre-start inspection: fasten RST/UVW power cables, CN1/CN2 connector terminals to avoid loose wiring alarms

  2. Clean radiator fin dust every 3~6 months to prevent overheat shutdown

  3. Cut all AC input power, wait ≥15min for DC bus capacitor full discharge before opening drive housing for maintenance (anti-electric shock)

  4. Strictly prohibit full parameter factory initialization; only adjust editable common parameters on site

9. COMMON FAULT & TROUBLESHOOTING

  1. Overheat Alarm: radiator dust clogging / poor cabinet ventilation / long-term overload → clean cooling system or reduce load

  2. Encoder Error: loose CN2 plug / damaged feedback cable / mismatched SM dedicated motor → check wiring and matching motor model

  3. Deceleration Overvoltage: install external braking resistor between P & BN terminals

  4. Parameter Write Fail: trying to modify Z/SM OEM locked core parameters (firmware protection, no hardware fault)

  5. Overload Alarm: mechanical transmission jamming / excessive load → inspect mechanical structure and reduce operating load
