CACR-SR12TZ9SM-Y12A
Description
1. Model Code Breakdown
2. Electrical Ratings
Input: 3-phase AC200~230V, tolerance -15%~+10%, 50/60Hz
Overload spec: 150% rated current for 60s continuous; 300% peak instantaneous overload ≤3s
DC bus nominal: DC280~320V; P/BN terminals for external regenerative brake resistor
Modulation: IGBT sine-wave PWM, max output frequency:300Hz
Weight: ~3.6kg, IP20, vertical cabinet mounting only
3. Ambient & Installation Conditions
Operating temp: 0℃~+55℃; Storage: -20℃~+70℃
Humidity:5%~80%RH non-condensing; derate power when altitude＞1000m
Vibration:10~55Hz, 0.5mm single amplitude
4. Control Features & Y12A Custom Restriction
Speed ratio:1:5000; full-load speed fluctuation ≤±0.01%; built-in notch filter for mechanical resonance suppression
Dual command input: analog ±10V / differential pulse, switched via internal parameters
Y12A exclusive limit:
All core loop gain, machine-specific application parameters are factory write-locked by Y12A dedicated firmware; full parameter initialization is strictly forbidden (will trigger runaway or machine fault). Only partial auxiliary gain supports limited auto-tuning.
RS422 communication: view real-time running data & last 10 fault logs; locked Y12A parameters cannot be modified via serial cable.
5. Terminal & Connector Definition
R/S/T: 3Φ main AC power input｜U/V/W: motor 3-phase power output
P/BN: External regenerative braking resistor connection terminals
CN1: Opto-isolated digital I/O block, fixed Y12A OEM signal assignment (most I/O mapping unchangeable by parameters)
CN2: SM dedicated encoder socket, only compatible with matched SM-type servo motor for Y12A machine
Front 7-segment LED: operating status + fault code display
6. Full Protection Functions
7. Replacement Rule
8. Maintenance Specification
Pre-start check: tighten power cables, CN1/CN2 plugs to avoid loose connection failure
Heat sink dust cleaning every 3~6 months to prevent overheat shutdown
Cut AC power, wait ≥15min for capacitor full discharge before opening casing for maintenance (anti-electric shock); prohibited full factory parameter reset.
9. Common Fault Diagnosis
Overheat Alarm: clogged radiator / poor cabinet ventilation / continuous overload → clean cooling or reduce load
Encoder Error: loose CN2 / damaged feedback wire / mismatched SM motor → inspect wiring & motor model
Deceleration Overvoltage: install external brake resistor across P & BN
Parameter write failure: modifying Y12A locked core parameters (software protection, not hardware breakdown)
Overload Alarm: mechanical stuck / excessive payload → check mechanical transmission
