A.2 Encoders and Phasing
A.2.1 Encoders
Encoders provide motor speed and position feedback
The regulation algorithms in the VDL200 drive are capable of controlling asynchronous motors and may or may not use
the speed measurement obtained from the encoder reading.

tions that have incremental sinusoidal channels.
For electrical connections always use good quality cables with shielded twisted pairs, according to the procedures and
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.
