Encoder systems

4.3.5.1

Overview

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 parameters:
The functions are assigned the following parameters in the commissioning software:
}
FBTYPE ("Feedback" window), primary feedback in the motor
}
EXTPOS ("Position Loop" window), secondary feedback, external position
}
GEARMODE ("Electronic Gearing" window), secondary feedback, externally driven
