Function Description
17
Speed limit for forward rota-
tion
The analog input is used as the output frequency limit value.
Analog input 100% is equivalent to Maximum Output Frequen-
cy (F03/A01).
When using this function, the concomitant use of Over Speed
Detection Level (d35) is recommended.

tion
20 Analog Input Monitor
By connecting analog signals to the inverter, the display coeffi-
cient can be used to convert and display analog signals as
temperature, pressure and other physical quantities via com-
munications.

21 PID feed forward
Enter the feedforward such as the temperature, pressure, etc.
in PID control. Set “1: Input terminal (AI1, AI2)” to PID Control
PID Feedforward Selection for Process Control (E121).

Using an Analog Input in Command System Parameters
• When using analog input terminals by the following functions, configure parameters for selecting the
commands of each function in addition to Input Terminal [AI1] Function Selection (E61), Input Termi-
nal [AI2] Function Selection (AII) (E62) and Input T
erminal [AI2] Function Selection (AIV) (E63).
When both are set to analog input, analog input signal is treated as a command.
