DETAILED PARAMETER DESCRIPTION
Description:
When the option 0 (P0221/P0222) is selected, AI3 is able to receive the speed reference, which will be sub-
jected to the speed limits(P0133 and P0134) and ramp action (P0100 to P0103).
Refer to Figure 5.24 on page 5-40.
The option 3, process variable, defines the AI3 input as the PID regulator feedback signal (e.g., pressure or
temperature sensor, etc.), provided that P0524 = 1.

NOTE!
Isolated Analog Input located on the Optional Board EBB. Refer to the Chapter 7 OPTIONAL AC-
CESSORIES AND BOARDS on page 7-1 of the User’s Manual.

Description:
Set the S4.1 switch on the EBB optional board to “ON” position when a current signal is used at the analog
input AI3.
Inverse reference is obtained with the options 2 and 3, i.e., the maximum speed is obtained with the minimum
reference.
