Yaskawa CACR-02-KIBA AC Servo Amplifier

Key Technical Specifications

The available exact-model documentation is primarily secondary-source material rather than a current Yaskawa OEM datasheet. In particular, the 1.9 A continuous and 5.7 A peak current figures should be treated as supplier-reported values until confirmed against the nameplate or original CACR documentation for the specific revision.

The exact model is also independently listed in industrial equipment inventories and used-equipment records as a Yaskawa servo amplifier, supporting its identification as a legacy motion-control component.

Product Introduction

The Yaskawa CACR-02-KIBA is a legacy AC ServoPack amplifier intended for small-capacity servo motion systems. Available technical references identify it as a 200 V-class amplifier for approximately 0.2 kW motor applications, using an analog command interface and incremental encoder feedback.

For maintenance and retrofit work, the critical selection points are the motor rating, amplifier revision, command signal, encoder interface, and cabinet wiring. Do not substitute another CACR-02 variant solely because its model number appears similar; the suffix defines important electrical and control characteristics.

Installation & Configuration Guide

Stage 1 — Pre-Installation Inspection

1. Record the existing amplifier model, revision, motor model, encoder type, and cabinet wiring.
2. Photograph all power, command, feedback, and control-terminal connections before removal.
3. Confirm the replacement nameplate reads CACR-02-KIBA.
4. Compare the replacement unit’s electrical ratings with the installed motor.
5. Verify the actual command interface and encoder wiring before energizing the replacement.

⚠️ Warning: The CACR family contains multiple model and suffix variations. Do not assume that CACR-02-KIBA can be replaced by another CACR-02 unit without an electrical compatibility check.

Stage 2 — Removal

1. Apply the machine’s approved electrical isolation/LOTO procedure.
2. Allow the drive’s DC bus capacitors to discharge according to the applicable service procedure.
3. Verify absence of hazardous voltage with an appropriate meter.
4. Label motor, encoder, command, and power conductors.
5. Remove the existing ServoPack without disturbing adjacent control wiring.

Stage 3 — Installation & Configuration

1. Mount the CACR-02-KIBA in the same cabinet orientation where practical.
2. Maintain adequate clearance around the heatsink and ventilation path.
3. Reconnect power wiring according to the applicable Yaskawa documentation.
4. Reconnect the analog command circuit and confirm signal polarity.
5. Reconnect encoder feedback with correct channel assignment and shielding.
6. Check motor-phase wiring before applying power.
7. Do not apply the analog command or enable signal until the motor and feedback circuits have been verified.

The available technical listing specifies panel mounting with heatsink and recommends maintaining airflow clearance; use the original installation documentation for the exact enclosure-clearance requirement for the installed revision.

Stage 4 — Commissioning

1. Energize the control system with the machine in a safe state.
2. Confirm amplifier status indicators before enabling motion.
3. Verify encoder feedback while the axis is stationary.
4. Apply a low-level command and confirm the expected direction.
5. Check motor current and abnormal vibration/noise.
6. Test acceleration and deceleration at reduced machine speed.
7. Confirm the emergency-stop and servo-disable circuits.
8. Run the axis through its normal operating range only after the low-speed test passes.

Estimated replacement time: 1–3 hours for an experienced technician when wiring documentation and a known-good replacement are available. Troubleshooting, parameter recovery, or encoder/motor incompatibility can extend commissioning time.

FAQ

Q1. What is the Yaskawa CACR-02-KIBA?
It is a Yaskawa AC ServoPack/servo amplifier used for small-capacity servo motion applications. Exact-model sources identify it as a CACR-series servo amplifier.

Q2. What motor capacity is assowith ?
Available technical references associate the unit with approximately 0.2 kW / 200 W-class Yaskawa servo motors. Confirm the motor model against the original Yaskawa compatibility documentation before installation.

Does use an analog command?
Yes. The available exact-model technical listing identifies a ±10 V analog command interface. Verify the actual controller output configuration before connecting the amplifier.

. Is interchangeable with oCR-02 models?
Not automatically. variants have different suffixes and electrical/control configurations. A model with a similar base number should be treated as a different part until voltage, motor rating, command interface, feedback, and wiring are confirmed.

. Is a current-generation Yaskawa drive?
It should be treated as a legacy ServoPack component for replacement planning. Current availability is primarily through industrial surplus, used, and repair channels; exact stock and condition vary by supplier.

Q6. What should be checked before purchasing a replacement?
Verify the complete model number , nameplate ratings, motor model, encoder type, command method, physical connectors, revision markings, and unit condition. For a used unit, request functional-test evidence where available.

Q7. Can a replacement be installed without changing the PLC or motion controller?
Potentially, if the replacement has the same electrical interface and control configuration. The existing controller’s analog command range, enable circuit, feedback interface, motor characteristics, and amplifier wiring must match. Verify precise compatibility with the OEM documentation before installation.
