Description
ANLG When a thermistor is connected to terminal [5]
and [L], the inverter checks for over-temperature
and will cause trip event and turn OFF output to
motor
OPEN A disconnect of the thermistor causes a trip
event, and the inverter turns OFF the motor
ON Starts the motor rotation
OFF No change to present motor status
ON Stops the motor rotation
OFF No change to present motor status
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
ON Temporarily disables PID loop control. Inverter
output 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)
ON Resets the PID loop controller. The main
consequence is that the integrator sum is forced
to zero
OFF No effect on PID controller
ON Accelerates (increases output frequency) motor
from current frequency
OFF Output to motor operates normally
ON Decelerates (decreases output frequency) motor
from current frequency
OFF Output to motor operates normally
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
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
