Description
ON powerup, the inverter will not resume a Run
command (mostly used in the US)
ON powerup, the inverter will resume a RUN
command that was active before power loss
OFF-to-ON transition signals the inverter that the
motor is already running at powerup (via bypass),
thus suppressing the inverter's motor output in Run
Mode
ON-to-OFF transition signals the inverter to apply a
time delay (B003), frequency match its output to
existing motor speed, and resume normal Run Mode
operation
The keypad and remote programming devices are
prevented from changing parameters
The parameters may be edited and stored
If A005=00, terminal [OI] is enabled for input.
If A005=01, terminal [O2] is enabled for input.
(Use terminal [L] for signal return.)
Terminal [O] is enabled for voltage input
(Use terminal [L] for signal return)
The trip condition is reset, the motor output is turned
OFF, and powerup reset is asserted
Normal power-on operation
Starts the motor rotation
No change to present motor status
Stops the motor rotation
No change to present motor status
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.
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.
Temporarily disables PID loop control. Inverter
output turns OFF as long as PID Enable is active
(A071=1).
Has no effect on PID loop operation, which operates
normally if PID Enable is active (A071 = 1).
Resets the PID loop controller. The main conse-
quence is that the integrator sum is forced to zero.
No effect on PID loop controller
Accelerates (increases output frequency) motor from
current frequency
No change to output frequency
