Frequency 0 Hz<br />

The dotted line denotes the output frequency obtained by combining the slowdown speed and the panel<br />

frequency adjustment speed.<br />

Note: If the operation frequency is set to the lower limit frequency, it will increase from 0Hz when power is<br />

turned on for the first time after the setting, and therefore the output frequency will not rise until the<br />

operation frequency reaches the lower limit frequency. (Operation at the lower limit frequency)<br />

In this case, the time required for the operation frequency to reach the lower limit frequency can be<br />

shortened by setting to the lower limit frequency. Frequency setting values does not change when<br />

command is nothing.<br />

Adjustment with pulse signals (Parameter-setting example 2)<br />

Set parameters as follows to adjust the frequency in steps of one pulse:<br />

, ≤ Pulse On time<br />

, = Frequency obtained with each pulse<br />

* The inverter does not respond to any pulses with an ON time shorter than that set with or<br />

. 12ms or more of clearing signal is allowed.<br />
