CACR-SR05AC1ER-Y3
CACR-SR05AC1ER-Y3 is an OEM parameter-locked 0.5kW AC servo drive from Yaskawa classic CACR-SR series, exclusively designed for YASNAC VS-800 CNC system and vintage Japanese CNC lathes and small machining centers. Its mainboard hardware is identical to standard universal CACR-SR05AC1ER, while suffix -Y3 represents factory pre-programmed locked OEM firmware with fixed machine-specific parameters. Core parameters such as servo gain and electronic gear ratio are write-protected from factory and cannot be modified or initialized arbitrarily. Only identical Y3 version can be used for direct replacement; non-Y standard drives will lead to positioning deviation or motor runaway after substitution. It pairs with USAREM-05 series 500W servo motors equipped with 1000P/R incremental encoders.
Description
1. General Overview
CACR-SR05AC1ER-Y3 is an OEM parameter-locked 0.5kW AC servo drive from Yaskawa classic CACR-SR series, exclusively designed for YASNAC VS-800 CNC system and vintage Japanese CNC lathes and small machining centers. Its mainboard hardware is identical to standard universal CACR-SR05AC1ER, while suffix -Y3 represents factory pre-programmed locked OEM firmware with fixed machine-specific parameters. Core parameters such as servo gain and electronic gear ratio are write-protected from factory and cannot be modified or initialized arbitrarily. Only identical Y3 version can be used for direct replacement; non-Y standard drives will lead to positioning deviation or motor runaway after substitution. It pairs with USAREM-05 series 500W servo motors equipped with 1000P/R incremental encoders.
2. Model Code Explanation
CACR is fixed series code for Yaskawa AC SERVOPACK servo amplifier. SR refers to three-control-mode platform supporting speed, position and torque control with ±10VDC analog command input tailored for VS-800 CNC. 05 stands for rated output power 0.5kW. AC denotes C-version mainboard with AC200V dedicated analog signal circuit. Digit 1 means internal feedback circuit matching 1000P/R incremental rotary encoder. E indicates incremental PG feedback specification and R is compatible with USAREM-R series servo motors. -Y3 is exclusive OEM firmware marking with factory-locked parameter set for specific machine tool configuration.
3. Electrical Specifications
Main power: three-phase AC200V~230V, 50/60Hz, voltage tolerance +10%/-15%; control power is independent single-phase AC200V~230V. Rated continuous output current is 4.2Arms and peak transient overload current reaches 11.0Arms. CN1 receives ±10VDC analog speed/position command from VS-800 controller; CN2 interface only supports 1000P/R incremental encoders and is incompatible with absolute encoders. Cooling method is natural air convection with IP20 protection grade for cabinet mounting only. Operating ambient temperature: 0℃~55℃; storage temperature: -20℃~85℃; working humidity ≤80%RH non-condensing; max installation altitude ≤1000m above sea level.
4. Key Product Features
All parameters under Y3 customized firmware are factory locked, unauthorized parameter tuning will result in positioning error, axis runaway or equipment alarm. Complete protection functions include overcurrent, overvoltage, undervoltage, overheat, encoder breakage, overload and regenerative circuit fault protection to ensure stable long-term operation. Compact rack-mounted structure facilitates convenient cabinet installation and quick field replacement during maintenance. Different from non-Y suffix CACR-SR05AC1ER with freely editable universal firmware, this Y3 customized unit cannot be directly replaced by standard version without parameter rewrite.
5. Application Range
Primarily used for original feed-axis spare replacement and breakdown maintenance of vintage Toyoda and other Japanese CNC machine tools configured with YASNAC VS-800 CNC system; also applied to dedicated maintenance of small customized precision automation equipment adopting ±10VDC analog control and incremental encoder feedback.
