Supplementary System Components

8.1 Signal amplifier electronics
The signal amplifier electronics is used to amplify the current signals for distan-
ces > 18 m between the encoder and the digital drive module for 1FT6 motors
whereby the current signals are converted into voltage signals.
Notice
Current signals should no longer be used for new applications, as voltage
signals offer higher noise immunity.
The signal amplification electronics can only be used in conjunction with
the Performance control of SIMODRIVE 611 digital.
