Manufacturer: Yaskawa Electric Corporation, JapanSeries: Discontinued analog servo drive exclusively for old Yasnac CNC machine feed axes, belonging to CACR-PR CNC positioning dedicated series.Model code explanation: CACR is Yaskawa traditional SERVOPACK series; PR stands for CNC positioning servo type; 01 means rated power 0.1kW; AD3NR is full OEM customized specification including special circuit layout and factory pre-set parameters for designated machine tools.Matching motor: Yaskawa USA series 0.1kW, single-phase 200V class AC servo motor with 5V incremental A/B/Z encoder.Availability: Original production stopped permanently; only used and refurbished spare parts for equipment maintenance.

Main power input: Single-phase AC200~230V, 50/60Hz with allowable voltage fluctuation ±10%.Rated output power 0.1kW, continuous rated output current 1.2A, with 300% instantaneous overload capacity for rapid axis acceleration.Three available control modes: position mode receives pulse or pulse-direction command with maximum input frequency 500kpps; speed control and torque control adopt ±10VDC analog command respectively. Parameters are set via onboard DIP switches and trim potentiometers without software programming.

CN1 is 24VDC opto-isolated digital I/O terminals including servo enable, emergency stop interlock, positioning completion signal and fault dry-contact relay output to CNC controller.CN2 is dedicated connector for motor incremental encoder feedback signal.Independent terminal blocks are arranged for main power input and three-phase motor output wiring following OEM customized pin definition.

Panel mounting inside control cabinet with IP20 protection grade, natural convection cooling without built-in cooling fan.Operating ambient temperature: 0℃~+40℃; storage temperature: -20℃~+60℃; ambient humidity 5%~85%RH non-condensing, free of corrosive gas and conductive dust. No power derating required under installation altitude of 1000 meters.

Complete protection covers overcurrent, overvoltage, undervoltage, motor overload, heatsink overheat, encoder disconnection and output short-circuit. Dry contact alarm output transmits fault signal to CNC main system for interlock stop.

Recommended substitute model: Yaskawa Sigma7 SGD7S-R90A00A (0.1kW, 200V input). Wiring modification and servo parameter tuning are necessary during field replacement.
