intelligent terminal assignment to/from [ROK] (option code 49) via the network.
However, you can still read an [ROK] input assignment over the network.
Description
Decelerates (decreases output frequency) motor from
current frequency
No change to output frequency
Clears the UP/DWN frequency memory by forcing it
to equal the set frequency parameter F001. Setting
C101 must be set=00 to enable this function to work.
UP/DWN frequency memory is not changed
Forces the source of the output frequency setting
(A001) and the source of the RUN command (A002)
to be from the digital operator
Source of output frequency set by (A001) and source
of run command set by (A002) is used
