References:
Analog Reference
A signal transmitted to the analog inputs 53 or
54, can be voltage or current.
Preset Reference
A defined preset reference to be set from -100% to +100% of the reference range. Selection of
eight preset references via the digital terminals.
Pulse Reference
A pulse frequency signal transmitted to the digital inputs (terminal 29 or 33).
Ref
MAX
Determines the relationship between the reference input at 100% full scale value (typically 10 V,
20mA) and the resulting reference. The maximum reference value set in par. 3-03.
Ref
MIN
Determines the relationship between the reference input at 0% value (typically 0V, 0mA, 4mA)
and the resulting reference. The minimum reference value set in par. 3-02.

Bus Reference
A signal transmitted to the serial communica-
tion port (FC port).
