Term Definition
Operation General term describing both ―forward run‖ and ―reverse run‖ implying that the inverter is in
operation.
Operation signal Signal requesting inverter operation, which is input by pressing the (drive) key on the
operation panel or using signals input through multifunctional control input terminals FR and
RR.
In operation (operating) Condition where the operation signal is being input or a drive signal is being output to the
main switching device. In the stop status, the operation signal is OFF, but the main switching
device operates until DC braking, etc. is completed.
In constant speed
(operation) Condition when the inverter is in operation at the frequency setting value.
Stopped Condition where the operation signal is not being input and the drive signal is not being output
to the main switching device. Even when the operation signal input is on, the input to the
multifunctional control input terminal MBS disables the drive signal output to the main
switching device.
Standby Condition where the operation signal is being input but there is no output for some reason, for
example, while waiting for the start delay time to expire or when the set frequency is lower
than the operation start frequency.
DC braking Condition where DC braking is applied when starting and stopping.
Frequency setting value
or set frequency Frequency set on F2101-F2116 and F1021.
Frequency value corresponding to an external signal when setting F1002=2-21 and 25-28 with
external signals for frequency setting.
Output frequency
or
frequency output value Actual inverter output frequency.

V/f mode
When the load is stable, the output frequency normally coincides with the frequency
setting value.

When used in vector control mode or for slip compensation in V/f mode, even if the load is
stable, the output frequency does not coincide with the frequency setting value but keeps
changing.
Command frequency Frequency value used by the inverter. As a command value frequency, its change in frequency
setting value not only depends on the results of controls such as the acceleration/deceleration
function and the current limiting function but also the actual output frequency. The command
frequency normally coincides with the set frequency at the end of acceleration/deceleration.

V/f mode: If there is feedback operation such as PID control mode, the command
frequency equals the output frequency.

When used in vector control mode or for slip compensation in V/f mode, the command
frequency and the output frequency may not match in this mode because the synchronous
speed specified by the number of motor poles and the command frequency is used as the
speed command.
