R88D-KT04H-Z

Overview of Omron R88D-KT04H-Z

The Omron R88D-KT04H-Z is a servo drive from the R88D-KT series designed for controlling AC servo motors with high precision and reliability. It supports AC power supply of 100 to 120 VAC at 50/60 Hz and is compatible with 400 W, 200 VAC servo motors like the R88M-K40030H series. This servo drive uses IGBT-driven PWM sinewave output for smooth motor operation and supports incremental encoder feedback with safety features like Safe Torque Off (STO).
