ANALOG INPUTS TO PROVIDE THE SPEED SIGNAL

Analog inputs are connected as shown below. It may be necessary to scale the response of the VFD to the

analog SPEED signal. See example of VFD Parameter Scaling in Figure 9 (F9).

EXAMPLES OF ANALOG INPUT CONNECTIONS.

WIRING TWO VFDS FOR LEADER-FOLLOWER OPERATION

One VFD can provide the SPEED signal to a second VFD, as shown below.

LEADER-FOLLOWER CONNECTION.

Connect VFDs as shown -

FA VFD will pass the Frequency

(Speed) Signal to the EA VFD.

Use shielded cable and ground

the shield to Terminal 1 on

either VFD

INSTALLATION

WIRING SCHEMATICS

NOTE: All wiring for analog signals connected to the

VFDs should be double - or single-shielded twisted-pair

cable. Ground the shield at one end of the cable only.

NOTE: Parameters 1501 and 1502 can be used to

scale the Analog Output of the Leader VFD in order to

offset or correct the speed of the Follower VFD.

If the FA VFD is controlled by an analog input signal,

it is likely that the FA VFD's response to the analog

input will need to be scaled, using parameters 1104,

1105, 1301 and 1302. See example of VFD Parameter

Scaling in Figure 9 (F9).

If both VFDs are to run at the same speed, no scaling

parameters need be applied to the EA VFD since it is

controlled as a "Follower".
