Drive Programming User’s Manual (I580-E2)
5-7 Multi-function Output Variables
You can execute the functions which can be allocated to the multi-function output terminals by using the
Drive Programming program. The following variables correspond to the functions which can be allo-
cated to the multi-function output terminals.
Setting each variable to 1 (ON) or 0 (OFF) causes the same operation as when the multi-function out-
put function turns the multi-function output terminal ON/OFF. You can monitor the status on the pro-
gram even if you do not set each function in the parameters Multi-function Output Selection (MX2:
C021 and C022/RX: C021 to C025 ) or Multi-function Relay Output (MA, MB) Function Selection
(C026). The Reference column in the following table shows the function setting data for the inverter. For
details on each function,
refer to the MX2 User's Manual (I570-E2) or the RX User's Manual (I560-E2) .
Precautions for Correct Use
When the Drive Programming program is stopped, the status of the multi-function output vari-
ables is not retained but updated according to the actual function status.
