TIDA-00177
概覽
The TIDA-00177 reference design is an EMC compliant industrial interface to a two-wire HIPERFACE DSL® encoder. Applications include industrial servo drives.
The design features a 3.3-V supply RS485 transceiver and line termination and coupling for encoder power over RS485 as per HIPERFACE DSL specification. The design has been tested up to 100m cable length with an integrated cable, where the encoder’s two-wire twisted pair was integrated in the same motor cable. The encoder connector output is protected against over-voltage and short circuit to prevent damage to an encoder or during a cable short. The design features an industrial compliant 24-V input with wide range from 18-36V. A 3.3V I/O connector with logic signals for easy interface to a host processor with HIPERFACE DSL Master IP Core is made available.
