Figure 6-5 Operation action
General term describing both "forward run" and "reverse run" implying that the inverter is in operation.
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.
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.
Condition when the inverter is in operation at the frequency setting value.
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.
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.
Condition where DC braking is applied when starting and stopping.
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.
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.
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.
