CACR-SR03TZ0SM
CACR-SR03TZ0SM is OEM customized 300W AC servo amplifier under Yaskawa classic CACR-SR series, specially developed to match Yasnac VS-800 CNC control system. It pairs with Yaskawa USAREM/USAF 0.3kW incremental encoder servo motors, serving as feed axis drive unit on legacy CNC lathes, milling machines and small precision machining centers. Original mass production is discontinued; it is mainly circulated as replacement spare part for old CNC equipment maintenance and overhaul globally.
Description
1. General Introduction
CACR-SR03TZ0SM is OEM customized 300W AC servo amplifier under Yaskawa classic CACR-SR series, specially developed to match Yasnac VS-800 CNC control system. It pairs with Yaskawa USAREM/USAF 0.3kW incremental encoder servo motors, serving as feed axis drive unit on legacy CNC lathes, milling machines and small precision machining centers. Original mass production is discontinued; it is mainly circulated as replacement spare part for old CNC equipment maintenance and overhaul globally.
2. Model Code Definition
CACR: General prefix of Yaskawa AC SERVOPACK amplifier series
SR: Multi-control platform supporting speed, position and torque three control modes via internal parameter setup
03: Rated 0.3kW output power specification
TZ: Exclusive customized mainboard with ±10VDC analog command circuit for VS800 CNC, AC200V voltage grade design
0SM: Dedicated encoder feedback circuit design for specified incremental pulse encoder, standard factory parameter configuration without extra Y-series locked OEM firmware (differentiated from Y01A suffix variant)
3. Electrical Specifications
Main power supply: 3-phase AC 200V~230V, 50/60Hz, voltage tolerance +10%/-15%; independent single-phase AC200~230V for control power input.Rated continuous output current: 3.0Arms; peak transient overload current: 8.5Arms to satisfy fast acceleration & deceleration heavy load demand.Command input: ±10VDC analog speed/position signal directly from VS800 CNC controller; compatible incremental encoder feedback ranging 1000PPR~6000PPR.Cooling: Natural air convection; protection grade IP20, must be installed inside electrical cabinet.Ambient condition: Working temperature 0℃~55℃, storage temperature -20℃~85℃; working humidity ≤80%RH non-condensing; max installation altitude below 1000m above sea level.
4. Core Product Features
This is VS800 system dedicated OEM servo unit, core loop gain and electronic gear ratio parameters are pre-calibrated at factory; arbitrary parameter modification may cause positioning deviation or abnormal motor running.Full-range built-in fault protection: overcurrent, overvoltage, undervoltage, overheat, encoder loss, overload and regenerative circuit malfunction protection for stable long-term operation.Compact rack-mounted structure for convenient cabinet installation and quick on-site replacement during equipment maintenance; mature vintage design with stable running performance after decades of field verification.
5. Application Range
Primarily used for drive replacement and maintenance of old CNC lathes/milling machines equipped with Yasnac VS-800 control system, also applicable for feed axis drive of small customized precision automation equipment.
