Introducing FORTiS-S FS
The FORTiS-S FS encoder series is a next generation linear enclosed absolute encoder for use in harsh environments such as machine tools.
Robust, rugged, high-performance position measurement over the encoder's long life is ensured by a range of innovative design features:
Ideal for machine tool applications
Renishaw has over 40 years of experience in the machine tool industry.
Our experts have designed the FORTiS series as a next generation linear enclosed absolute encoder for use in harsh environments.
|Serial interfaces||Description||Data sheet|
|BiSS® Safety||Renishaw supports BiSS Safety (unidirectional) open protocol for absolute encoders. BiSS Safety is a high-speed serial interface, perfect for dynamic axes that require high acceleration, smooth velocity control, excellent bi-directional repeatability and rock-solid positional stability.||FORTiS-S FS BiSS Safety|
FORTiS FS encoders with Siemens DRIVE-CLiQ serial interface allow the connection of encoders and direct measurement systems with SINUMERIK and SINAMICS drive components.
Optional Advanced Diagnostic Tool ADTa-100
The FORTiS encoder system is compatible with the Advanced Diagnostic Tool ADTa-100 and ADT View software. They provide comprehensive real-time encoder data feedback to aid more challenging installations and diagnostics. The intuitive software interface can be used for:
- Remote calibration
- Signal optimisation over the entire axis length
- Digital readout of encoder position (relative to the scale)
- Exporting and saving data
- Setting zero
