CACR-SR03AB1ER-Y3

CACR-SR03AB1ER-Y3 is No.3 OEM customized analog SERVOPACK amplifier based on standard CACR-SR03AB1ER base platform, discontinued Yaskawa drive exclusively matched for designated Yasnac VS-800 CNC lathe/vertical machining center feed axis, rated power 300W(0.3kW), rated continuous output current 3.0A. Suffix -Y3 = 3rd factory special custom version: exclusive CN1 50-pin control connector pin assignment + factory locked fixed parameter group, different from standard non-Y, Y1 customized versions; cross replacement without rewiring & parameter modification is invalid.

Description

1. Product Overview

Suffix -Y3 = 3rd factory special custom version: exclusive CN1 50-pin control connector pin assignment + factory locked fixed parameter group, different from standard non-Y, Y1 customized versions; cross replacement without rewiring & parameter modification is invalid.

Full Model Code Definition

CACR-SR: Classic analog servo series for Yasnac VS CNC differential pulse command control
03: Rated output power 300W
A: Standard main control PCB specification
B: Power circuit revised version
1: Differential line-driver pulse position input
E: For 1500PPR incremental encoder feedback circuit
R: Standard universal housing
-Y3: Third dedicated OEM customization (unique pinout + locked preset parameters for exclusive machine builder)

2. Electrical Ratings

Main power input: Single/3-phase AC180V~AC230V, 50/60Hz industrial power supply
Matched servo motor: Yaskawa USAM-03 / USAF-03 300W servo motor with 1500PPR incremental encoder; core control parameters are factory locked for designated matched motor only
Control structure: Current + speed + position triple closed-loop; analog speed command function partially disabled by Y3 factory custom setting in most scenarios

3. Environmental & Installation Parameters

Operating temperature: 0℃~+55℃; storage temperature: -20℃~+60℃
Relative humidity ≤95%RH (non-condensing), IP20 protection grade, cabinet-only installation, max installation altitude ≤1000m; net weight ≈3.5kg

4. Terminal & Connector Difference vs Standard / Y1 Model

R/S: Main AC power input terminals; U/V/W: Servo motor three-phase winding wiring; spare terminals for external dynamic braking resistor
CN1 (50Pin control port, core Y3 modification): Pin definition totally differs from standard CACR-SR03AB1ER and Y1 variant; customized signal allocation for OEM servo enable, ready output, fault alarm, CNC interlock signals; direct plug-in interchange impossible without custom wiring rearrangement
CN2 (20Pin encoder port): Pin layout keeps universal standard, same as base model & Y1 version

5. Parameter & Operation Features (Key Y3 Customized Item)

All core gain, speed-loop and position-loop Cn parameters are factory write-protected locked, users cannot revise critical parameters via front panel buttons; only minor auxiliary function settings are adjustable.

Power-on inspection & jog test operation steps consistent with standard model: pre-wiring short-circuit check → power on, single-digit LED standby display; power off over 3min to save modified auxiliary parameters after setting finished.

6. Protection & Fault Code (Identical to standard/Y1 unit)

Built-in overcurrent, overvoltage, undervoltage, overload, overheat, encoder break protection; unified fault codes:

Code 1: Overcurrent alarm; Code 2: Input power abnormal; Code A: Encoder disconnection; Code F: Internal overheat; Code C: Control board hardware fault
Fault reset: Eliminate failure root cause → cut input power ≥30s then restart drive.

7. Replacement & Maintenance Rules

Replacement compatibility: Only CACR-SR03AB1ER-Y3 can direct plug replacement; standard CACR-SR03AB1ER / -Y1 cannot substitute unless full CN1 pin rewiring + full parameter rewrite to OEM Y3 setting
Periodic maintenance: Quarterly radiator & cooling fan dust cleaning, terminal screw retightening; cut power ≥10min before cabinet opening to avoid residual high-voltage electric shock risk

8. Application Scope

Custom-tailored for specific OEM Yasnac VS-800 CNC lathe and small machining center feed axis; cannot be matched with general third-party CNC system without professional engineering modification.
