System compatibility

CACR-SR20BB1AM belongs to Yaskawa SR servo family,matched with corresponding 2.0kW USAREM servo motor. The AM suffix defines dedicated encoder interface for original machine design. Widely used in chip mounters,precision X-Y positioning platforms and special automation equipment. This is a discontinued legacy servo amplifier for old production line maintenance spare replacement.

Function

CACR-SR20BB1AM serves as high precision AC servo amplifier unit. It receives pulse position instructions from upper controller to achieve fast speed and torque adjustment. Built-in multi-level hardware protection to safeguard servo motor and drive. It adopts dedicated AM encoder signal processing circuit and supports general motion parameter tuning.

Installation

Mount CACR-SR20BB1AM on control cabinet panel. Wire power cable,motor cable and encoder feedback cable according to wiring drawing. Complete parameter setup and motor auto-tuning via Yaskawa servo software.

Interface

‑Power terminals for main power and motor power output

‑AM dedicated encoder feedback connector

‑Digital I/O terminal block for pulse command and alarm output

‑Front panel LED indicators for power,running and fault state

‑Onboard current loop processing and multi-point fault diagnosis circuit

Circuit feature

Compact rugged PCB layout,equipped with surge and ESD suppression circuit. Fast current loop response,stable positioning performance,good anti-interference performance for industrial cabinet environment. Standard factory firmware preloaded for AM base variant.

Feature

CACR-SR20BB1AM is obsolete Yaskawa SR series servo spare part. Typical failures include power board damage,encoder port breakdown,overload and overvoltage alarms. Check motor and cable integrity before replacement. AM variant must match corresponding AM type servo motor,direct substitution without hardware validation is not recommended.

Diagnostic

When overvoltage,overcurrent,overload,encoder signal loss or overheating occurs,the drive triggers corresponding alarm codes and sends fault signal to upper PLC or controller.

Built‑in function

Precision closed-loop position,speed and torque control,real-time encoder signal monitoring,multi-level hardware fault protection for servo motion system,used as servo amplifier spare replacement.

Product Brief

CACR-SR20BB1AM is Yaskawa SR series 2.0kW AC SERVOPACK servo drive with AM encoder interface for dedicated semiconductor and automation machinery. Confirm motor matching before ordering. ESD protection required during handling and installation.
