PARAMETERS

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.

•

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.

CAUTION

When the Pr. 2 setting is higher than the Pr. 13 "starting frequency" value, note that the

motor will run at the set frequency by merely switching the start signal on, without

entering the command frequency.

Pr. 13 "starting frequency"

Pr. 903 "frequency setting voltage gain"

Pr. 905 "frequency setting current gain"
