Overview 4- ][Funktion_Geber_Uebersicht_DD5
Each closed drive system normally requires at least one encoder, which
transmits actual values (e.g. speed, position) from the motor to the servo
amplifier. Feedback to the servo amplifier can be transmitted in digital or
analogue, depending on the encoder type.
Up to three encoders can be used in parallel.
Setting:
The functions are assigned the following parameters in the commission-
ing software:
 FBTYPE ("Feedback" window), primary feedback in the motor
 EXTPOS ("Position Loop" window), secondary feedback, external po-
sition
 GEARMODE ("Electronic Gearing" window), secondary feedback, ex-
ternally driven
A detailed description of the parameters is available in the commission-
ing software's online help.
The servo amplifier supports all standard encoder types.
The table below provides an overview of the supported encoder types
and their corresponding parameters and connectors.
