Description
YASKAWA CACR-02-KIBA | SERVOPACK Amplifier Spec Sheet
Product Introduction
When an older CNC machine or automated assembly cell shuts down because a legacy servo drive blows an output stage, hunting for a functional replacement can halt production lines for weeks. The Yaskawa CACR-02-KIBA is not a modern software-heavy drive; it is a heavy-duty analog-interface SERVOPACK engineered to deliver high-response closed-loop motor control under demanding industrial duty cycles.
Mounted directly inside the control cabinet backplane, the unit takes low-level motion command signals and scales them into high-power multi-phase current to drive the servo motor precisely. It demands clean AC supply input, solid chassis grounding, and accurate tuning potentiometer settings, but once bolted into place, it restores the exact dynamic performance required by legacy Yaskawa motion systems.

Application Scenarios & Pain Points
- Legacy CNC Machining Centers: Older axis drives used to suffer from thermal drift or component aging, causing contouring errors. Swapping in a verified CACR-02-KIBA restored precise tracking and axis stability.
- Automated Material Handling: Without reliable current loop execution, rapid acceleration profiles would trigger overcurrent fault shutdowns. This Yaskawa drive handles aggressive motion demands without hesitation.
- Special Purpose Production Machinery: A manufacturing facility avoided an expensive, complete electrical architecture refit by dropping a verified surplus CACR-02-KIBA straight into an existing control panel bay.
QA & Live Testing SOP (Trust Signal)
Legacy servo drives demand absolute verification before energizing high-voltage DC buses. Every incoming Yaskawa CACR-02-KIBA goes through a strict multi-point test protocol:
- Visual & Component Inspection: We check internal electrolytic capacitors for bulging or leakage, examine power transistor terminals for oxidation, and verify board cleanliness.
- Powered Bench Verification: The unit is mounted to a dynamic test rig, supplied with nominal control and power voltages, and checked under simulated motor load conditions to verify speed loop stability and fault tripping.
- ESD-Safe Packaging: Units are sealed in heavy-duty moisture-barrier antistatic bags. When you unbox the CACR-02-KIBA, it is ready for immediate critical-path installation.
Field Engineer’s Pitfall Guide
- ❗ DC Bus Voltage Hazards: Never touch internal terminals or remove connectors immediately after powering down; residual high-voltage charge on the internal capacitors can cause severe electrical shock.
- ❗ Potentiometer Calibration Slips: Always record your original gain and offset potentiometer settings before swapping units, or the new drive may cause axis hunting or overshoot on startup.
- ❗ Feedback Cable Shielding: Failing to maintain continuous shield grounding on the encoder feedback line will inject electrical noise, causing erratic motor jitter or sudden overspeed trips.
Intent-Driven Field FAQ
Can I use a modern digital Sigma-series drive to replace the Yaskawa ?
Direct replacement with a modern drive is usually impossible without changing the motor and rewriting the control interface, because the relies on specific legacy analog command structures and feedback protocols.
Is this specific unit brand new or refurbished?
This inventory consists of verified surplus—un-installed factory backup stock or professionally tested working pulls preserved in climate-controlled storage.
What causes the amplifier to throw an overcurrent or overload fault?
Overload trips are typically triggered by mechanical binding in the axis ball screw, shorted motor power leads, or improperly tuned acceleration/gain potentiometers on the front panel.
What kind of warranty comes with this purchase?
Every surplus drive includes a standard 1-year functional replacement warranty covering any electrical or mechanical defects under normal operating conditions.
Do I need special software to set up this drive?
No PC software is required for basic setup; adjustments are managed physically via onboard tuning potentiometers and hardware jumper selections.
