Chapter 6 - Parameter Description [FU2]
This must be set when using an external DB resistor.
The duty is calculated by ' %ED=Decel time * 100 /
(Accel time + Steady speed time + Decel time + Stop
status time)' .

FU2-81 ~ FU2-90: 2 Motor Related Functions
nd
These functions are displayed only when one of the
multifunction inputs is set at ' 2nd func' in I/O-12 to I/O-14.
When using two motors with an inverter by exchanging
them, different values can be set for the 2
using the multifunction input terminal.
Following table is the 2 functions corresponding to the
nd
1 functions.

is not defined to ' 2nd Func' or if it is not ON. The 2
function parameters are applied when the multifunction
input terminal set to ' 2nd Func' is ON. Parameters not
listed on the table above are applied to the 2

This is useful for programming multiple inverters to have
same parameter settings. The LCD keypad can read
(upload) the parameter settings from the inverter
memory and can write (download) them to other
inverters. This function is only available with LCD
keypad.
