HIPERFACE DSL (вложено) Key features of HIPERFACE DSL 2-wire physical interface are: • Digital interface compliant to RS-485 standard with a transfer rate of 9.375 MBaud • Half-duplex communication with the encoder through dual wires • Power supply and communication with the encoder carried out using the same dual wires. The connection cables to the encoder are routed as a shielded, twisted pair cable in the power supply cable to the motor. Therefore, no separate cable for the encoder plug connector is required • Cable length between the frequency inverter and the encoder up to 100 m, without degradation of the operating performance
