5 1 Introduction Layout 1.1 Brief description Motor connection (U, V, W) This technology option permits the evaluation of encoder systems in accordance with the HIPERFACE DSL protocol. The two-wire encoder cable can be integrated directly into the motor cable. A motor temperature sensor is connected inside the motor to the encoder and evaluated by it. The data are also transmitted via the encoder interface. In this way a one-cable motor system is realised. On the usage of a motor brake, it is connected directly to the one-cable interface (X8.1 and X8.2). X8.1 X8.2 X8.1 X8.2 HIPERFACE DSL is a purely digital protocol that only requires a minimum of connection cables between the servocontroller and the motor feedback system. The robustness of the protocol makes it possible to connect the motor feedback system via the motor connection cable. Motor feedback systems with the HIPERFACE DSL interface can be used in all power ranges and significantly simplify the implementation of an encoder system in the drive: y Uniform digital interface (RS485) y Analogue components for the encoder interface are superfluous y Standardised interface between frequency inverter application and protocol OK logic Figure 1.2 One-cable interface layout ServoOne junior (X8.1 and X8.2) DSL connection MFB system Motor Drive Figure 1.1 Basic principle Hiperface DSL Source: Sick-Stegmann 5 Introduction

"Local Administrator"). A modified parameter must always be saved in the device. A parameter, as far as it can be changed "online", causes an immediate reaction in the device, for this reason the entry is always to be checked.
