The signal amplifier electronics unit is used to amplify current signals for dis-
tances > 18 m (59 ft) between the encoder and digital drive module and for con-
verting current signals to voltage signals for 1 V
Notice
Because voltage signals provide a higher noise immunity, current signals
should no longer be used for new users.
The signal amplifier electronics can be used only in conjunction with the
Performance, High Standard or High Performance controller of the
SIMODRIVE 611 digital.
