5. Basic parameters<br />

Before you operate the inverter, the parameters that you must first program are the basic parameters.<br />

• Function<br />

1) For acceleration time 1 programs the time that it takes for the inverter output frequency to go from<br />

0Hz to maximum frequency .<br />

2) For deceleration time 1 programs the time that it takes for the inverter output frequency to got<br />

from maximum frequency to 0Hz.<br />

5.1.1 Automatic acceleration/deceleration<br />

This automatically adjusts acceleration and deceleration time in line with load size.<br />

=<br />

* Adjusts the acceleration/deceleration time automatically within the range of 1/8 to 8 times as long as the<br />

time set with the or , depending on the current rating of the inverter.<br />

=<br />

* Automatically adjusts speed during acceleration only. During deceleration, speed is not adjusted<br />

automatically but reduced at the rate set with .<br />
