Program features 35
Two external control locations, EXT1 and EXT2, are available. The user can select
the sources of the start and stop commands separately for each location by setting
parameters
. Selection between EXT1 and EXT2 is done via any binary
source such as a digital input or fieldbus control word (parameter
). The source of reference is selectable for each operating mode separately.
Communication fail functionality
The communication fail functionality ensures continuous process without
interruptions. If there is a communication loss, the drive automatically changes the
control location from EXT1 to EXT2. This enables process to be controlled, for
example, with the drive PID controller. When the original control location recovers,
the drive automatically switches control back to the communication network (EXT1).
