Note: The inverter will not start if the frequency setting signal is less than the value set in Pr. 13 "starting
frequency".
For example, when 5Hz is set in Pr. 13, the motor will start running when the frequency setting signal
reaches 5Hz.
CAUTION
When the Pr. 13 setting is lower than the Pr. 2 value, note that the motor will run at the
set frequency by merely switching the start signal on, without entering the command
frequency.
