22 F/R FWD, REV
(3-wire interface)
ON Selects the direction of motor rotation: ON = FWD.
While the motor is rotating, a change of F/R will start
a deceleration, followed by a change in direction
OFF Selects the direction of motor rotation: OFF = REV.
While the motor is rotating, a change of F/R will start
a deceleration, followed by a change in direction
23 PID PID Disable ON Temporarily disables PID loop control. Inverter out-
put turns OFF as long as PID Enable is active
(A071=01)
OFF Has no effect on PID loop operation, which operates
normally if PID Enable is active (A071=01)
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 controller
27 UP Remote Control UP
Function (motorized
speed pot.)
ON Accelerates (increases output frequency) motor from
current frequency
OFF Output to motor operates normally
28 DWN Remote Control Down
Function (motorized
speed pot.)
ON Decelerates (decreases output frequency) motor
from current frequency
OFF Output to motor operates normally
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
