• Specifying the initial value for the UP/DOWN control
Specify the initial value to start the UP/DOWN control.
Data for H61

Initial value to start the UP/DOWN control
Mode fixing the value at "0":
The inverter automatically clears the value to "0" when restarted (including powered
ON). Speed up by the UP command.
Mode holding the final output frequency in the previous UP/DOWN control:
The inverter internally holds the last output frequency set by the UP/DOWN control and
applies the held frequency at the next restart (including powering ON).
At the time of restart, if an UP or DOWN terminal command is entered before the internal frequency
reaches the output frequency saved in the memory, the inverter saves the current output frequency into the
memory and starts the UP/DOWN control with the new frequency.
Pressing one of these keys overwrites the frequency held in the inverter.
Initial frequency for the UP/DOWN control when the frequency command source is switched
When the frequency command source is switched to the UP/DOWN control from other sources, the initial
frequency for the UP/DOWN control is as listed below:
