Description
Switch from normal (1st) to 2nd motor parameters for gener-
ating frequency output to motor
Frequency output uses 2nd-stage acceleration and decelera-
tion values
Causes output to turn OFF, allowing motor to free run (coast)
to stop
At OFF to ON transition, inverter latches trip event and
displays E12 (until a reset occurs)
On powerup, the inverter will not resume a Run command
that was active before power loss (mostly used in the US)
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
ON condition: If A005=00, terminal [OI] is enabled for
input. If A005=01, terminal [O2] is enabled for input. (Use
terminal [L] for signal return.)
OFF condition: Terminal [O] is enabled for voltage input (use
terminal [L] for signal return).
ating frequency output to motor
Resets the trip condition, turns OFF the motor output, and
asserts powerup reset
Starts the motor rotation
Stops the motor rotation
Selects the direction of motor rotation: ON =FWD;
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).
Resets the PID loop controller. The main consequence is that
the integrator sum is forced to zero.
To select the source of internal speed loop gain...
OFF selects parameters H050 to H052 (or H250 to H252 for
2nd motor); ON selects alternate parameters H070 to H072
Accelerates (increases output frequency) motor from current

Decelerates (decreases output frequency) motor from current
