Analog Input – 2-wire Transmitter
The picture above shows a 2-wire 4-20mA current transmitter. This type of
transmitter requires power from the drive. The positive side of the transmitter is wired to
terminal 12 or 13(+24Vdc). Terminal 39 (common for power) must be wired to terminal 55
(common for the Analog Inputs). The negative side of the transmitter is wired to terminal 60
to complete the circuit.
Parameter 314 is setup for Feedback, with parameter 315 setting the minimum
(4mA) and parameter 316 setting the maximum (20mA). If the transmitter goes to 0mA,
parameter 317 sets the timeout, default is 10sec, and parameter 318 sets the function if the
transmitter goes.
The range of the transmitter is set in parameter 414, minimum feedback, and set in
parameter 415, maximum feedback. Parameter 416 sets the engineering units for the
transmitter, from a list of 40 items.
