2.Electrical Specifications
Main power input: three-phase AC200V~230V, fluctuation range -15%~+10%, compatible with 50Hz/60Hz power grid; independent single-phase AC200V~230V supplies control circuit power.Rated three-phase output AC0~230V, continuous output 7.6A/1.0kW.Overload specification: 150% rated load continuous running for 60 seconds, 300% peak overload limited within 3 seconds for startup acceleration.DC bus nominal voltage DC280V~320V; P and BN terminals reserved for external regenerative braking resistor connection for frequent heavy-load rapid deceleration.IGBT sine-wave PWM modulation, max output frequency 300Hz for high-speed motor operation.
3.Environment & Mechanical Data
Working ambient temperature 0℃~+55℃; storage temperature -20℃~+70℃; relative humidity 5%~80%RH non-condensing, protection grade IP20, vertical cabinet panel installation required.Max allowed installation altitude below 1000 meters above sea level, anti-vibration specification 10~55Hz, single amplitude 0.5mm.Natural air cooling without built-in cooling fan, net weight approx 2.4kg.
4.Control Performance
Speed adjustment ratio up to 1:5000, full-load steady speed deviation within ±0.01%.CN2 feedback connector connects incremental encoder matched with designated OEM 1kW Yaskawa servo motor, standard 6000PPR encoder supported.Built-in digital notch filter to eliminate mechanical resonance and low-speed vibration.Basic motor static parameter auto-tuning available, but core motion parameters (speed loop gain, position gain, electronic gear ratio, accel/decel time) preset and locked under Y114 OEM program, modification forbidden arbitrarily; only minor auxiliary parameters allow user adjustment.Three control modes can switch via editable non-locked parameters.
5.Terminal & Interface Function
R/S/T: three-phase main AC power input terminals; U/V/W: three-phase motor power output terminals; P/BN: external regenerative brake resistor wiring terminals.CN1 opto-isolated I/O terminal adopts fixed Y114 OEM signal definition: fixed assignment for servo enable, forward/reverse overtravel limit, emergency stop, servo ready output, fault alarm output; I/O function rearrangement via parameters is blocked by customized firmware.CN2 dedicated incremental encoder feedback port; onboard RS422 serial port with Yaskawa private protocol for parameter reading/writing and real-time running status monitoring.
6.Built-in Functions & Full Protection
Complete protection items: overcurrent, overvoltage, undervoltage, drive overheat, encoder fault, motor overload, internal short-circuit protection; drive stores latest 10 historical fault codes for maintenance inquiry.Internal dynamic braking circuit absorbs normal deceleration regenerative energy; external brake resistor needed only for frequent emergency stop and heavy cutting load.Dual high/low speed gain setting preset under Y114 program, cannot reset freely.
7.Application & Replacement Instruction
-Y114 customized servo exclusively matched with specific OEM CNC machine 1.0kW servo motor; replacement must use identical full part number CACR-SR10BB1AM-Y114.Ordinary CACR-SR10BB1AM without Y114 suffix cannot directly substitute due to locked special parameters and fixed CN1 I/O logic; standard universal model needs full parameter redo and I/O redefinition before trial run.Mainly applied for fixed brand vertical machining center, CNC lathe feed axis drive.
8.Routine Maintenance Rules
Check tightness of power cable, motor cable and CN2 encoder connector before power-on; locked Y114 core parameters cannot be modified without machine manufacturer authorization.Ensure electrical cabinet ventilation unobstructed during operation; stop continuous operation if inner cabinet temperature exceeds 55℃.Cut off main AC supply and wait more than 15 minutes for DC bus capacitor complete discharge before opening drive cover to avoid electric shock hazard; clean radiator dust every 3~6 months to prevent overheat alarm.
9.Common Fault Troubleshooting
Overheat alarm: blocked radiator dust, overhigh cabinet ambient temperature or long-term continuous overload operation.Encoder error alarm: loose CN2 plug or damaged encoder feedback cable.Overvoltage alarm during frequent fast heavy deceleration: add external regenerative resistor on P/BN terminals.Parameter modification failure alarm: caused by Y114 OEM parameter write protection, locked items cannot be rewritten.
