2. Full Model Code Breakdown

1. CACR-SR: Vintage SERVOPACK series dedicated to Yasnac CNC feed axis control

2. 01: 100W output power

3. A: Standard control board specification

4. C: Input power class = Single/3-phase AC200V

5. 1: Digital pulse command input for position control (differentiated from “2” which is ±10V analog command)

6. E: Compatible with servomotors equipped with 1500PPR incremental encoder

7. R: Standard terminal layout & internal wiring specification

8. Y102: Custom OEM variant

   Predefined factory parameters, modified I/O pin assignment and customized internal firmware for matching Yasnac VS-800 CNC controller; non-standard general-purpose drive and cannot be directly replaced by non-Y suffix standard CACR-SR01AC1ER.
