CACR-SR05AA2AH-Y314 is an OEM customized 0.5kW AC servo amplifier from Yaskawa classic CACR-SR series, exclusively engineered to match YASNAC VS-800 CNC control system for legacy Toyoda and Japanese-made CNC lathes and small machining centers. It is designed to pair with Yaskawa USAREM series 500W incremental encoder servo motors. Original production has been discontinued, and the unit is only available as replacement spare part for maintenance and overhaul of aging machine tools. The suffix Y314 represents exclusive factory pre-programmed and locked OEM parameters tailored for designated machine specifications.

CACR is the standard series prefix for Yaskawa AC SERVOPACK drives. SR stands for multi-functional control platform supporting speed, position and torque three optional control modes via internal parameter setup. 05 denotes rated output power of 0.5kW. AA refers to standard mainboard equipped with ±10VDC analog command input circuit complying with VS-800 CNC requirement under AC200V power grade. Digit 2 means built-in feedback circuit for 1500P/R incremental rotary encoder. AH represents standard terminal definition of this hardware version. Y314 is dedicated customized firmware code; core parameters such as servo loop gain and electronic gear ratio are pre-calibrated and locked at factory with no permission for arbitrary user editing.

Main power input is three-phase AC200V~230V, 50/60Hz with voltage tolerance +10%/-15%, and control circuit is powered by independent single-phase AC200V~230V. Rated continuous output current is 4.2Arms while instantaneous peak overload current reaches 11.0Arms to fulfill rapid acceleration and deceleration dynamic load demands. CN1 port receives ±10VDC analog instruction from VS-800 CNC controller; CN2 feedback interface is exclusively compatible with incremental encoder rather than absolute encoder. Natural air convection cooling is adopted with IP20 protection grade, so installation inside control cabinet is mandatory. Operating ambient temperature ranges from 0℃ to 55℃, storage temperature ranges from -20℃ to 85℃, working humidity is limited below 80%RH without condensation, and maximum applicable installation altitude is within 1000 meters above sea level.

All parameters under Y314 customized firmware are factory locked; unauthorized parameter modification will result in positioning inaccuracy, motor runaway or mechanical origin missing failure. Complete protective functions including overcurrent, overvoltage, undervoltage, overheat, encoder disconnection, overload and regenerative circuit fault protection are integrated to secure stable long-term operation. Compact rack-mounted structure facilitates convenient cabinet installation and quick on-site replacement during equipment repair. Since incremental encoder is configured, homing operation is required after every power restart, differing from absolute encoder servo models. Standard non-Y suffix CACR-SR05AA2AH cannot directly substitute this model without parameter modification on account of exclusive Y314 fixed parameters.

This servo drive is mainly used for feed-axis replacement and breakdown maintenance of vintage Toyoda CNC lathes and small machining centers fitted with YASNAC VS-800 system; it also applies to servo retrofit of small customized precision automation equipment using ±10VDC analog control and incremental encoder feedback.
