REMARKS
If the set frequency is less than Pr. 2, the output frequency is clamped at Pr. 2 (will not fall below Pr. 2). Note that Pr. 15 Jog
frequency has higher priority than the minimum frequency.
When the Pr. 1 setting is changed, frequency higher than the Pr. 1 setting can not be set by
When performing a high speed operation at 120Hz or more, setting of Pr. 18 High speed maximum frequency is necessary.
( Refer to the chapter 4 of the Instruction Manual (applied)).
Note that when Pr. 2 is set to any value equal to or more than Pr. 13 Starting frequency, simply turning on the start signal
will accelerate the motor to the set frequency of Pr. 2 according to the set acceleration time even if the command
frequency is not input.
