Description
Communication break detection active. Upon a
communication break, the drive generates a warning
FBA A communication) and sets the speed to the value
defined by parameter 22.41 Speed ref safe

WARNING! Make sure that it is safe to continue
operation in case of a communication break.

Time delay.
Selects the type and scaling of reference 1 received from
fieldbus adapter A. The scaling of the reference is defined by
parameters 46.01...46.04, depending on which reference
type is selected by this parameter.
Type and scaling is chosen automatically according to the
currently active operation mode as follows:
Operation mode
