Why choose Fuji Electric?
3.2 kHz frequency response
A proprietary control algorithm delivers a 3.2 kHz speed-loop frequency response to shorten cycle time.
24-bit encoder precision
Servo motors use a 24-bit incremental/absolute encoder for very fine positioning resolution.
Built-in functional safety
STO per IEC 61800-5-2 is standard, with optional SS1, SLS, SBC, and SSM configurable by parameter.
Compact, panel-saving design
The amplifier is about 12% smaller in footprint than previous models and supports side-by-side mounting.
