1. Model Code Definition

2. Electrical Specifications

• Input Power: Single/Three-phase AC200~230V, 50/60Hz

• Rated Continuous Output Current: 3.0A; Peak Overload Current: 8.6A

• Matching Servo Motor: Yaskawa USAF-03 / USAM-03 300W servo motor with 4000PPR incremental encoder; 1500PPR standard encoder motors incompatible under Y114 factory preset parameters

• Control Mode: Triple closed-loop (Current loop + Speed loop + Position loop); default: differential pulse position command, analog ±10V speed input available per Y114 custom setting

• Output: 3-phase sine-wave PWM modulation, 0~230V AC to servo motor U/V/W terminals

3. Terminal & Connector Description

Main Power Terminals

• R, S: Main AC input power terminal; spare terminal reserved for external dynamic braking resistor wiring

• U, V, W: Three-phase output to servo motor stator windings

Control Connectors

• CN1 (50Pin): Custom exclusive Y114 pinout for Servo Enable, Drive Ready output, Fault Alarm output, CNC interlock signal; pin assignment totally different from standard BB1AF base model

• CN2 (20Pin): Exclusive encoder feedback port, only for 4000PPR incremental encoder cable connection

4. Environmental & Mechanical Data

• Operating Ambient Temp: 0℃ ~ +55℃; Storage Temp: -20℃ ~ +60℃

• Relative Humidity: ≤95% RH, non-condensing; Max installation altitude ≤1000m above sea level

• Protection Grade: IP20 (cabinet indoor mounting only, forbidden open-air installation)

• Cooling Mode: Natural convection air cooling; Net Weight ≈2.95kg

5. Y114 Exclusive Customized Features

1. Core parameters (speed loop gain, position loop gain, electronic gear ratio) factory write-protected, cannot modify via front panel key operation; only partial auxiliary parameters adjustable

2. I/O signal logic (enable active level, alarm output polarity, ready signal definition) pre-programmed for original Yasnac VS-800 machine tool, inconsistent with standard BB1AF/Y101/Y110 variants

3. Manual jog operation mode & free command source switching locked by built-in factory firmware

4. Original design for feed axis drive of customized small CNC lathe & vertical machining center with VS-800 CNC system

6. Built-in Protection & Fault Alarm Codes

Reset rule: Cut off main input power ≥30s after troubleshooting before restart the servo unit

7. Replacement Instruction

1. Only CACR-SR03BB1AF-Y114 supports plug-and-play direct replacement

2. Ordinary standard CACR-SR03BB1AF or other Y suffix custom version (Y110/Y111/Y114 different code) cannot direct substitute; full CN1 rewiring + complete parameter rewriting required for alternative replacement

8. Basic Operation Guide

1. Pre-power check: Confirm R/S power wiring, U/V/W motor wiring, CN2 encoder wiring no short/open circuit

2. Power-on sequence: First switch on CNC control cabinet power, then servo main AC power

3. Normal status: 7-segment display shows steady standby digit; no alarm code popping up

4. Shutdown sequence: Cut off servo power first, then CNC host power supply
