<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.
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.
