7.1.4.1
Frequency reference
The frequency reference source is programmable for all control places except
PC
, which always
takes the reference from the PC tool.
Remote control place (I/O A):
The source of frequency reference can be selected with parameter
Remote control place (I/O B):
The source of frequency reference can be selected with parameter
Local control place (Keypad):
If the default selection for parameter P3.3.1.7 is used the reference
set with parameter P3.3.1.8 applies.
Remote control place (Fieldbus):
The frequency reference comes from fieldbus if the default value
for parameter P3.3.1.11 is kept.
