[FUN 47] is used to provide motor overload
detection. When the output current of the inverter has
reached the “Overload Warning Level” and after the
[FUN 48] on-delay time has been reached, a multi-
output signal may be turned on.
For example, define multi-output OC1 in [I/O 07 ~
09] (OC1 Output) to OL. The multi-output is open
collector (24V DC, 50mA).
