Yaskawa CACR-SR07BE12M Compact servo amplifier
Introduction
The Yaskawa CACR-SR07BE12M is a compact servo amplifier (servo drive) from Yaskawa’s industrial motion-control family designed to drive AC servomotors in precision positioning and speed-control applications.
It provides closed-loop current/velocity/position control, safety and protection functions, and interfaces for common industrial encoders and fieldbus/control signals.
Technical parameter table (categories — verify exact values in official datasheet)
Model: CACR-SR07BE12M
Function: AC servo amplifier / servo drive
Supply voltage: (200–230) V AC class typical for SR series — confirm exact min/max
Rated output current / continuous current: (specify from datasheet) — check official value
Peak/short-time current: (specify from datasheet) — check official value
Control modes: position, speed, torque (closed-loop)
Encoder input: incremental / absolute encoder support (A/B/Z or SSI/EnDat depending on option)
Command interfaces: pulse train, analog, ±10 V, serial/fieldbus option (depends on model/config)
Protection features: overcurrent, overvoltage, undervoltage, overheat, motor stall detection
Cooling: forced-air / fan-cooled (model dependent)
Mounting: panel/rail mounting, compact footprint
Communication/options: I/O terminals for enable/servo on/alarms; optional network modules (EtherCAT, MECHATROLINK, PROFIBUS etc. — depending on configuration)
Ambient conditions: typical operating temperature range and humidity — see datasheet Note: Exact numeric values (currents, voltages, dimensions, encoder type, network options) must be taken from the Yaskawa product datasheet or nameplate for CACR-SR07BE12M.
