6.1.1 Information on use

After mains on, an initialization may have to be performed depending on the encoder
type. This may take up to 5 seconds, depending on the encoder type. This time can
be eliminated by powering the basic device and the encoder using an external
DC 24 V supply.
When the encoder or motor (including motor encoder) are replaced, re-calibration will
typically be required for the absolute position. This applies typically to the encoder-
internal value (depending on the encoder type used, this value cannot be changed),

applications (configuration x40).
Note:
The signals provided by the encoder are used in the EM-ABS-01 for various plausibility
checks. This makes the system more fail-safe and less prone to unwanted interfe-
rence.
During operation, the encoders and communication with the encoder are monitored.
Critical conditions are reported via device errors. Most error evaluations will only be
performed when the power output stage is activated.

When an absolute value encoder is used, referencing is not required after
encoder or motor replacement to ensure correct function of the ACU
device. Adjustments of
After encoder or motor replacement, correct function of the system is
achieved by performing a referencing operation or offset adjustment.
Some absolute value encoder types enable to "zero" or change the posi-
tion transmitted by the encoder. Do not use this function, as this will
change the commutation angle in synchronous motors for
and correct speed control is not guaranteed.
Changing the value while the system is in operation can result in signifi-
cant failures of the system.
