12.2.4 References
Analog reference
A signal transmitted to the analog inputs 53 or 54 can be voltage or current.
Binary reference
A signal transmitted via the serial communication port.
Preset reference
A defined preset reference to be set from -100% to +100% of the reference range. Selection of 8 preset references via the digital
terminals. Selection of 4 preset references via the bus.
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, 20 mA) and the resulting reference. The
maximum reference value is set in parameter 3-03 Maximum Reference.
Ref
MIN
Determines the relationship between the reference input at 0% value (typically 0 V, 0 mA, 4 mA) and the resulting reference. The
minimum reference value is set in parameter 3-02 Minimum Reference.
