5.1.4.4 IN-50 I2 Terminal as the Frequency Reference Source
You can set and modify a frequency reference by applying inputs to the I2 terminal. Inputs can be 0(4)-
20mA or I2 can be used as a second voltage input (0-10VDC) based on the position of switch SW4.
5.1.4.4.1 Setting a Frequency Reference for 0(4) - 20mA Input
You can modify the frequency reference using the I2 input terminal. First with SW4, select I2 (left is default)
for the current input. Set DRV-07 (Frequency reference source) to ‘5 (I2)’ and apply 0(4)–20 mA input
current to I2. Scaling of the input current is done with IN-53 ~ IN-56. View the input current at IN-50.

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 60.00 Hz and default settings are used for IN-
53–56, 20 mA input current (max) to I2 will produce a frequency
reference of 60.00 Hz.
• If IN-56 is set to 50.00%, and default settings are used for IN-01
(60 Hz) and IN-53–55, 20 mA input current (max) to I2 will produce
a frequency reference of 30.00 Hz (50% of 60 Hz).
IN-50
I2 Monitor
Monitors 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.
