Configuring the Option Board
All Option Board parameters are stored in the MX2 Inverter. This allows
for easy replacement of the Option Board without the need to re-configure.
After connecting the Option Board to an MX2 Inverter for the first time
however, proceed with the following steps:
Step 1
It is recommended to set C102 = 3 to prevent the Inverter reset input and
Stop/reset button from interfering with Option Board during operation
(Setting C102 to another value causes the Option Board to reset when a trip
condition is cleared). Use the Inverter keypad to set C102 to 3.
Step 2
Change the control method for the RUN command and frequency reference
to Optional Board.
Note
When node address are assigned automatically (rotary switch set
to 00), make sure the resulting axis numbers do not conflict with
axes already assigned to other drives. This will result in a configu-
ration error.
