Output Frequency Range (Pr. 1, Pr. 2, Pr. 18) - Mitsubishi FR-E520-0.1KN Instruction Manual

4.2.2 Output frequency range (Pr. 1, Pr. 2, Pr. 18)

Pr. 1 "maximum frequency"
Pr. 2 "minimum frequency"
Pr. 18 "high-speed maximum frequency"
Used to clamp the upper and lower limits of the output frequency. Used for high-speed
operation at or over 120Hz.
! 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.
" To perform operation over 120Hz, set the upper limit of the output frequency in Pr. 18.
(When the Pr. 18 value is set, Pr. 1 automatically changes to the frequency in Pr. 18.
Also, when the Pr. 1 value is set, Pr. 18 automatically changes to the frequency in
Pr. 1.)
" Use Pr. 2 to set the lower limit of the output frequency.
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.
