Chapter 6. Function Description (I/O)
1.9) Analog Hold
When FUN_02 is set to “analog” and one of the selected terminal set to “Analog Hold” is ON, inverter fixes its output
frequency, regardless of the frequency reference change. The changed frequency reference is applied when the terminal
is OFF. This function is useful when a system requires constant speed after acceleration.
1.10) Main Drive
When an option board is installed and used for the frequency setting and the RUN/STOP command, the inverter
operation can be changed to manual using this function without changing the user-setting parameter values. To make
this function active, set the selected terminal for “Main Drive” to ON during stop. When this terminal is ON, changing
operating speed reference, operating method, and torque limit is done via Keypad ONLY. To turn off the terminal, the
changed value is not saved and previous value is restored. Changing control mode during Main Drive operation is
available only when the 2nd function is defined using terminal ON/OFF.
The following parameters cannot be changed while Main Drive function is active.

1.11) 2nd Func (the 2
nd
function setting)
The iV5 inverter has the capability to control 2 motors independently. A second motor may be active by selecting one
terminal for this function and turn it ON. 2
