Starting Frequency (Pr. 13); Load Pattern Selection (Pr. 14) - Mitsubishi Electric FR-A520-0.4K-NA Instruction Manual

z

Starting frequency (Pr. 13)

Pr. 13 "starting frequency"
You can set the starting frequency between 0 and 60Hz.
Set the starting frequency at which the start signal is switched on.

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.

Load pattern selection (Pr. 14)

Pr. 14 "load pattern selection"
You can select the optimum output characteristic (V/F characteristic) for the application and load
characteristics.
