 Setting the minimum frequency (Pr.2)
• Set Pr.2 Minimum frequency to the lower limit of the output frequency.
• If the set frequency is Pr.2 or less, the output frequency is clamped at Pr.2 (does not fall below Pr.2).
NOTE
• To operate with a frequency higher than 60 Hz using frequency-setting analog signals, change the Pr.125 (Pr.126) (frequency
setting gain) setting. Simply changing the Pr.1 and Pr.18 settings does not enable the operation at a frequency higher than
60 Hz.
• Under PM motor control, the upper and lower limits are for the commanded frequency. The final output frequency that is
decided by each control may exceed the lower or upper limits.
• When Pr.15 Jog frequency is equal to or less than Pr.2, the Pr.15 setting takes precedence.
• If a jump frequency that exceeds Pr.1 (Pr.18) is set for the 3-point frequency jump, the maximum frequency setting is the set
frequency. If the jump frequency is less than the setting of Pr.2, the jump frequency is the set frequency. (The set frequency
can be equal to or less than the frequency lower limit.) When stall prevention is activated to decrease the output frequency,
the output frequency may drop to Pr.2 or below.
CAUTION
• Note that when Pr.2 is set to any value equal to or higher than Pr.13 Starting frequency, simply turning ON the start
signal runs the motor at the frequency set in Pr.2 even if the command frequency is not given.
