Output Frequency Range (Pr. 1, Pr. 2) - Mitsubishi Electric FR-F500 Instruction Manual

4.2.2 Output frequency range (Pr. 1, Pr. 2)

Pr. 1 "maximum frequency"
Pr. 2 "minimum frequency"
Used to clamp the upper and lower limits of the output frequency.
Can be used to set the upper and lower limits of motor speed.

<Setting>
• Use Pr. 1 to set the upper limit of the output frequency. If the frequency of the frequency command entered is
higher than the setting, the output frequency is clamped at the maximum frequency.
• Use Pr. 2 to set the lower limit of the output frequency.
Note: When the frequency setting analog signal is used to run the motor beyond 60Hz, change the Pr. 903
and Pr. 905 values. If Pr. 1 is only changed, the motor cannot run beyond 60Hz.
When the Pr. 2 setting is higher than the Pr. 13 value, note that the motor will run at the
set frequency by merely switching the start signal on, without entering the command
frequency.
