These functions are displayed only when one of the multifunction inputs is set at '2nd func'
in I7 to I24.
The purpose of these parameters is to provide the user with a second set of motor
parameters selected with a digital input. This can be useful on test stands, where a user will
be testing different types of applications.
In the table below, the 1st functions are applied if the multifunction terminal is not defined
to '2nd Func' or if it is not ON. The 2nd function parameters are applied when the
multifunction input terminal is set to '2nd Func' and is ON. Parameters not listed on the
table below are applied to the 2nd motor as well as the 1st motor.
The 'User V/F' function of F29 [V/F Pattern] is used for both the 1st motor and the 2nd
motor.
