Group 3.3: Control reference settings

The frequency reference source is programmable for all control places except PC, which always takes
the reference from the PC tool.
Auto control place (I/O A): The source of frequency reference can be selected with parameter P3.3.3.
Auto control place (I/O B): The source of frequency reference can be selected with parameter P3.3.4.
Hand control place (Keypad): If the default selection for parameter P3.3.5 is used the reference set
with parameter P3.3.6 applies.
Auto control place (Fieldbus): The frequency reference comes from fieldbus if the default value for pa-
rameter P3.3.9 is kept.
