1. Model Code Explanation
CACR stands for Yaskawa Yasnac VS800 full digital AC SERVOPACK servo amplifier series. SR represents three-mode switchable servo supporting position, speed and torque control via internal parameter setup. 05 means rated matching motor power is 0.5kW. S is control mainboard S hardware version designed for standard incremental A/B/Z encoder circuit. B refers to Version B power board with standard internal power layout. 1 indicates three-phase AC200V~230V main input power, 50/60Hz. A means CN2 feedback port exclusively for differential incremental encoder, no absolute encoder hardware supported.

Y187 is exclusive factory custom OEM suffix, with factory pre-locked fixed parameter group and customized terminal signal logic for dedicated CNC original equipment application, parameter default cannot be randomly modified without equipment mechanical alteration.
2. Electrical Basic Rating
Main power input: three-phase AC200~230V, voltage tolerance +10%/-15%, 50/60Hz. Independent single-phase AC200~230V dedicated terminals for control circuit power supply. Rated continuous output power 0.5kW, rated continuous output current 3.2A. Peak overload current 9.6A for max 3 seconds (300% overload), 150% overload sustainable for 60 continuous seconds. DC bus operating voltage DC280~320V, P and N spare terminals reserved for external regenerative braking resistor connection for frequent deceleration heavy load scenarios.
3. Environmental & Mechanical Parameter
Allowable working ambient temperature 0℃~+55℃, short time peak working temperature below 60℃; storage temperature range -20℃~+70℃. Working humidity 5%~80%RH without dew condensation, protection grade IP20, only for cabinet vertical panel installation. Net unit weight about 4.8kg, max applicable installation altitude within 1000 meters above sea level, anti-vibration specification 10~55Hz with 0.5mm amplitude.
4. Control Performance
Adopts IGBT sine wave PWM dual closed-loop control of speed loop and position loop. Speed adjusting ratio reaches 1:5000, full load steady speed precision within ±0.01%. Main command source is analog ±10VDC speed/torque signal, external differential pulse serves as auxiliary position command with max input pulse frequency 500kpps. CN2 only matches standard differential incremental A/B/Z phase encoder, multi-turn absolute encoder unavailable. Built-in mechanical resonance suppression digital notch filter function, three control modes can be switched freely by modifying internal parameters. Y187 custom version locks partial core parameters by factory setting to match original host CNC system configuration.
5. Terminal & Connector Definition
R/S/T terminals for three-phase main power input; U/V/W terminals connect three-phase servo motor wiring; P/N for external brake resistor. CN1 is opto-isolated digital I/O terminal block with fixed Y187 OEM signal definition, including servo enable, forward/reverse limit, home signal input, emergency stop input, servo ready output and fault alarm output. CN2 dedicated wiring for incremental encoder feedback only. Onboard RS422 communication port for parameter reading, writing and running status monitoring with exclusive Yaskawa private protocol.
6. Complete Protection Functions
Built-in full protection items: overcurrent, overvoltage, undervoltage, input phase loss, drive overheat, motor overload, encoder wire break, regeneration overvoltage and CPU operation error protection. Fault codes displayed via front digital nixie tube, latest 10 groups of fault history data stored inside drive for maintenance check. Y187 customized program adds special external fault detection logic matching original machine peripheral circuit.
7. Application & Operation Notice
This Y187 custom servo is exclusively tailored for old model CNC machine feed axis with analog voltage control, cannot directly replace non-Y suffix standard CACR-SR05SB1AF due to different I/O logic and preset parameters. Before power-on, check power cable, encoder wire and signal terminal tightness to avoid short circuit or wrong wiring. Keep cabinet ventilation unblocked during operation, prohibit long time continuous running above 55℃ ambient temperature. When replacing spare drive, must select identical Y187 suffix model to guarantee normal machine operation.
8. Daily Maintenance & Troubleshooting
Inspect terminal tightness and radiator dust accumulation every 3 to 6 months; cut off main power and wait minimum 15 minutes for internal capacitor full discharge before disassembling maintenance to prevent electric shock. Overheat alarm mainly caused by blocked radiator or overhigh cabinet temperature; encoder error mostly from loose CN2 plug or broken feedback cable; overvoltage alarm under frequent rapid deceleration needs external brake resistor fitted on P/N terminals.
