4.1.3.3 Setting a Reference Frequency using Input Current (I2)
You can set and modify a frequency reference using input current at the I2 terminal after
selecting current input at SW 2. Set the Frq (Frequency reference source) code in the
Operation group to 5 (I2) and apply 4–20mA input current to I2.

Description
In.01 Freq at
100%
Configures the frequency reference for operation at the maximum current
(when In.56 is set to 100%).
• If In.01 is set to 40.00Hz, and default settings are used for In.53–56,
20mA input current (max) to I2 will produce a frequency reference of
40.00Hz.
• If In.56 is set to 50.00 (%), and default settings are used for In.01
(60Hz) and In.53–55, 20mA input current (max) to I2 will produce a
frequency reference of 30.00Hz (50% of 60Hz).
In.50 I2 Monitor
Used to monitor input current at I2.
In.52 I2 Filter
Configures the time for the operation frequency to reach 63% of target
frequency based on the input current at I2.
