1. Product Overview

Difference vs standard CACR-SR05AZ1SR (no Y suffix): Standard = full parameter editable; -Y4 = parameter lock, dedicated for specific OEM lathe mechanical tuning, cross substitution causes positioning deviation/alarm.

2. Model Code Definition

• CACR: Yaskawa classic AC SERVOPACK servo amplifier series

• SR: 3-in-1 control (Speed/Position/Torque), ±10VDC analog command input for VS800 CNC controller

• 05: Rated power: 0.5kW(500W)

• AZ: Z-version mainboard circuit (different PCB layout vs AY/AD series, exclusive internal control circuit)

• 1: PG feedback only for 1000P/R incremental encoder

• SR: Hardware compatible with USAREM-R series servo motor

• -Y4: OEM custom lock code → factory preset fixed parameter set, parameter write protection enabled

3. Electrical Specifications

• Main power: 3Φ AC200V~230V, 50/60Hz, tolerance +10%/-15%

• Control power: Independent single-phase AC200V~230V

• Rated continuous output: 4.2Arms; Peak overload current:11.0Arms

• CN1: Analog ±10V position/speed command from VS-800 CNC unit

• CN2: Dedicated 1000PPR incremental encoder feedback port

• Cooling: Natural convection cooling; IP20 indoor cabinet mounting only

• Ambient: Operation 0~55℃, storage -20~85℃, RH＜80% non-condensing, installation altitude ≤1000m

4. Core Features

1. Y4 locked firmware: Gain/electronic gear ratio locked by factory firmware, parameter initialization forbidden, no universal parameter setting like non-Y standard AZ1SR model.

2. Full fault protection: Overcurrent, overvoltage, undervoltage, overheat, overload, encoder break, regeneration error protection.

3. DIN rail compact cabinet installation, original drive for vintage Japanese VS-800 CNC lathes.

4. PCB is AZ layout, incompatible with AD1KR-Y101/Y111 & AY1SR hardware, cannot direct swap replacement.
