Parameters
3–51
24 PIDC PID Reset ON Resets the PID loop controller. The main conse-
quence is that the integrator sum is forced to zero.
OFF No effect on PID loop controller
26 CAS Control gain setting ON Selects alternate parameters H070 to H072 for the
source of the internal speed loop gain
OFF Selects parameters H050 to H052 (or H250 to H252
for 2nd motor) for the source of internal speed loop
gain
27 UP Remote Control
UP Function (motor-
ized speed pot.)
ON Accelerates (increases output frequency) motor from
current frequency
OFF No change to output frequency
28 DWN Remote Control
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
32 SF1 Multispeed bit 1 ON Logical 1
