System compatibility
CACR-SR20BB1AF belongs to Yaskawa SR servo family,matched with corresponding 2.0kW USAREM servo motor. The AF hardware defines dedicated encoder interface for original production machine. 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-SR20BB1AF 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 AF encoder signal processing circuit,supporting motion parameter tuning for original machine motion requirements.
Installation
Mount CACR-SR20BB1AF 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
‑AF 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 AF base variant.
Feature
CACR-SR20BB1AF is obsolete Yaskawa SR series servo spare part.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. AF variant must match corresponding AF 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-SR20BB1AF is Yaskawa SR series 2.0kW AC SERVOPACK servo drive with AF encoder interface for dedicated semiconductor and automation machinery. Confirm motor matching before ordering. ESD protection required during handling and installation.
