A.3 Encoders and encoder expansion cards
A.3.1 Encoders
Encoders provide motor speed and position feedback
The regulation algorithms in the ADV100 drive are capable of controlling asynchronous motors, it may or may not use
the speed measurement obtained from the encoder reading. The regulation algorithm needs an encoder that also
allows the absolute motor position to be veried.
Encoders must be tted to the motor shaft using anti-backlash couplings.
For electrical connections always use good quality cables with shielded twisted pairs, according to the procedures and
specications described in the following paragraphs.
The conguration parameters for each encoder can be found in the ENCODER CONFIG.
In the event of an encoder malfunction the drive generates the Speed fbk back loss alarm and the cause of the mal-
function is shown in parameter 2172 SpdFbkLoss code.
If the encoder is not used by the regulation algorithm the drive still manages the encoder position reading but does not
generate an alarm in case of malfunctioning.
