CACR-SR03AB1ER-Y1

CACR-SR03AB1ER-Y1 is a custom OEM modified SERVOPACK based on standard CACR-SR03AB1ER base model, discontinued Yaskawa analog servo amplifier exclusively for Yasnac VS-800 CNC machine feed axis control, rated power 300W (0.3kW), rated continuous output current 3.0A. Suffix -Y1 = Factory customized special version: modified CN1 control connector pin definition + pre-locked factory fixed parameter set for specific OEM lathe/MC equipment; cannot directly interchange with non-Y standard CACR-SR03AB1ER without wiring rearrangement and parameter reset.

Description

1. Product Overview

Suffix -Y1 = Factory customized special version: modified CN1 control connector pin definition + pre-locked factory fixed parameter set for specific OEM lathe/MC equipment; cannot directly interchange with non-Y standard CACR-SR03AB1ER without wiring rearrangement and parameter reset.

Full Model Code Breakdown

CACR-SR: Classic analog servo platform for Yasnac VS CNC analog pulse command control
03: Nominal rated power 300W
A: Standard main control PCB layout
B: Revised internal power circuit version
1: Differential line-driver pulse position command input
E: For 1500PPR incremental encoder feedback circuit
R: Standard base hardware structure
-Y1: No.1 custom modification specification (unique CN1 pin assignment + factory preset fixed gain parameters for designated OEM machine)

2. Electrical Specifications

Input Power: Single/Three-phase AC180~230V, 50/60Hz industrial mains
Matching Servo Motor: Yaskawa USAM-03 / USAF-03 300W servo motor with standard 1500PPR incremental encoder; Y1 preset parameters are locked to match original OEM matched motor only
Control Mode: Current+Speed+Position triple closed-loop, differential pulse position instruction from Yasnac CNC mainboard; analog speed command function disabled by Y1 factory customization in most cases

3. Ambient & Installation Parameter

Operating Temp: 0℃ ~ +55℃; Storage Temp: -20℃ ~ +60℃
Humidity ≤95%RH non-condensing, IP20 protection, cabinet-only installation, max altitude ≤1000m; net weight ≈3.5kg

4. Terminal & Connector Difference vs Standard Non-Y Model

R/S: Main AC power input; U/V/W: Servo motor three-phase winding wiring; spare terminals for external dynamic braking resistor
CN1 (50Pin control connector): Core Y1 modification: Pinout definition differs from standard CACR-SR03AB1ER; custom signal allocation for OEM CNC interlock, enable, alarm output; direct plug replacement invalid without adapter wiring
CN2 (20Pin): Encoder connector remains standard universal pin layout, same as base model

5. Parameter & Operation Feature (Key Y1 Custom Point)

All core Cn-series gain & function parameters are factory write-locked for matched OEM equipment, user cannot modify key parameters via front panel button; only minor auxiliary setting adjustable.

Power-on operation flow same as standard unit: pre-wiring short-circuit inspection → energize, front single-digit LED standby display; jog test available for no-load motor check after power-on ≥3min for parameter saving.

6. Protection & Fault Code (Identical with standard CACR-SR03AB1ER)

Built-in OCC, OVP, UVP, overload, overheat, encoder break protection; fault codes consistent:

1: Overcurrent; 2: Power supply abnormal; A: Encoder open circuit; F: Drive overheat; C: Control board failure
Fault reset: Remove fault cause → power off ≥30s for reset restart.

7. Replacement & Maintenance Rules

Replacement: Only CACR-SR03AB1ER-Y1 interchange directly; standard CACR-SR03AB1ER cannot substitute unless rewire CN1 pins + full parameter rewrite matching OEM setting
Maintenance cycle: Quarterly radiator/fan dust removal, terminal screw tightening; power off ≥10min before casing disassembly to avoid residual high voltage electric shock

8. Typical Application

Customized for specific OEM Yasnac VS-800 CNC lathe & small vertical machining center feed axis; not universal for general third-party CNC equipment without engineering modification.
