FOC signal transmission for SSI + HTL/TTL (up to 400 kHz)
Accessories – electronic
- Module set (transmitter FO-TX-4 + decoder FO-DX-4) for absolute values (SSI) and incremental signals (HTL or TTL)
- Extremely fast and highly precise FOC signal transmission up to 1000 m (patent pending)
- Designed for highly dynamic control of drives, including motor commutation
- Just one fiber optic cable carries all data, integrated monitoring
The speedsters for absolute values and incremental signals
Comprising the FOC transmitter FO-TX-4 and the FOC decoder FO-DX-4, the innovative module set operates extreme quickly, highly precise and completely interference-free. It transmits incremental signals (HTL or TTL) as well as absolute values (SSI). These high-performance FOC modules always prove their value as powerful team players when high frequencies are demanded of the SSI encoder to ensure reliable and robust drive control, for example, motor commutation in mining or steel industry applications. In combination with the SSI absolute encoders ASS(H) 40 or ASSH 60 (equipped with an additional incremental output), the FOC modules FO-TX-4 and FO-DX-4 also guarantee interference-free and fast signal transmissions in those environments up to 1000 m, even at clock frequencies >2 MHz. All data is transmitted along one fiber optic cable, whose performance is monitored continuously by means of integrated cable break and status monitoring.
