DOWN Function
(motorized speed pot.)
ON
Decelerates (decreases output frequency) motor from
current frequency
OFF
No change to output frequency
29
UDC
Remote Control Data
Clearing
ON
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.
OFF
UP/DWN frequency memory is not changed
31
OPE
Operator Control
ON
Forces the source of the output frequency setting
(A001) and the source of the RUN command (A002)
to be from the digital operator
OFF
Source of output frequency set by (A001) and source
of run command set by (A002) is used
