Analog Input – 3-wire Transmitter
The picture above shows a 3-wire 4-20mA current transmitter. This type of
transmitter also requires power from the drive. Terminal 12 on the drive sends power to the
transmitter l24Vdc. A common terminal on the transmitter is wired back to terminal
39 (common for power) on the drive. The signal from the transmitter is wired to terminal 60
(mA input) on the drive. There must be a connection between terminal 55 (AI common) and
terminal 39, in order for the signal to work.
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.
