Description
1. Basic Information
Manufacturer: Yaskawa Electric Corporation, JapanSeries: Obsolete analog servo drive for old Yasnac CNC machine feed axes under CACR-PR positioning dedicated series.Model explanation: CACR refers to classic Yaskawa SERVOPACK series; PR represents CNC positioning servo; 01 stands for rated power 0.1kW; AD4NR is OEM custom specification with special internal circuit and factory preset parameters for specific machine tool equipment.Matching motor: Yaskawa USA series 0.1kW, 200V grade AC servo motor fitted with 5V A/B/Z incremental encoder.Availability: Original production discontinued; only used or refurbished spare parts available for maintenance.
2. Electrical Specifications
Input supply: Single-phase AC200~230V, 50/60Hz, permissible voltage deviation ±10%.Rated output power 0.1kW, continuous rated output current 1.2A, 300% transient overload capability for axis acceleration.Three optional control modes: Position mode accepts pulse or pulse-direction signal with maximum input frequency 500kpps; speed and torque control use ±10VDC analog command input. Parameters are adjusted by DIP switches and trim potentiometers without PC programming.
3. Interface Configuration
CN1 consists of 24VDC opto-isolated digital I/O including servo enable, emergency stop interlock, in-position completion and fault dry-contact relay output to CNC controller.CN2 is dedicated connector for motor incremental encoder feedback wiring.Separate terminal blocks are designed for power input and three-phase motor output based on customized OEM pin assignment.
4. Mechanical & Environmental Data
Cabinet panel mounting with IP20 protection grade, natural cooling without built-in fan.Operating ambient temperature:0℃~+40℃; storage temperature:-20℃~+60℃; ambient humidity 5%~85%RH non-condensing, no corrosive gas or conductive dust. No power derating needed below 1000m installation altitude.
5. Protection Functions
Full protection including overcurrent, overvoltage, undervoltage, motor overload, heatsink overheat, encoder disconnection and output short-circuit. Fault dry-contact signal feeds back to CNC system for fault interlock stop.
6. Replacement Recommendation
Alternative model: Yaskawa Sigma7 SGD7S-R90A00A (0.1kW, 200V). Wiring adjustment and on-site parameter tuning are required during replacement.
