System compatibility
CACR-SR15BZ1SM belongs to Yaskawa SR servo series, matched with corresponding 1.5kW USAREM series servo motor. The M suffix represents dedicated encoder hardware interface and signal definition for absolute encoder. Widely used in chip mounters, automation positioning platforms and special-purpose machine tools. This is a discontinued legacy servo amplifier for old production line maintenance spare replacement.
Function
CACR-SR15BZ1SM is high precision AC servo amplifier unit. It receives pulse position command from upper controller, realizes fast-response speed and torque regulation. Built-in comprehensive hardware protection functions to safeguard servo motor and drive hardware. Optimized encoder signal processing circuit for M-type absolute encoder.
Installation
Mount CACR-SR15BZ1SM on control cabinet panel. Wire main power cable, motor power cable and encoder feedback cable following wiring diagram. Complete parameter configuration and motor auto-tuning via Yaskawa servo engineering software.
Interface
‑Power terminals for main power and motor power output
‑Absolute encoder feedback connector
‑Digital I/O terminal block for pulse command and alarm signal
‑Front panel LED indicators for power,operation and fault status
‑Onboard current loop processing and multi-point fault diagnosis circuit
Circuit feature
Compact rugged PCB design, built-in surge and ESD suppression circuit. High-speed current loop response, stable positioning performance, strong anti-interference capability for industrial cabinet environment. Dedicated encoder circuit for M variant.
Feature
CACR-SR15BZ1SM is obsolete Yaskawa SR series servo drive spare part. Common faults include power board damage,encoder port failure,overload alarm and overvoltage trip. Verify motor and cable health before module replacement. M encoder variant must match corresponding absolute encoder motor.
Diagnostic
When overvoltage,overcurrent,overload,encoder signal loss or overheat is detected,the drive outputs dedicated alarm code and sends fault signal to upper PLC or controller.

Built‑in function
Precision position,speed and torque closed-loop control,real-time encoder feedback monitoring,multiple hardware fault protection for servo motion system,used as servo amplifier spare replacement.
Product Brief
CACR-SR15BZ1SM is Yaskawa SR series 1.5kW AC SERVOPACK servo drive with dedicated M absolute encoder interface for dedicated automation machinery. Confirm motor model matching before ordering. ESD protection required during handling and installation.
