Case 1:If frequency set value (Analog setting via voltage, current, RS485 or keypad) is within the range of skip frequency, it maintains the low limit value. If the set value is outside the range, it increases the frequency up to the set value.

Case 2:In the case of a decreasing frequency setting, if the frequency set value (Analog setting via voltage, current, RS485 or keypad) is within the range of skip frequency, it maintains skip frequency high value. If the setting is outside the range, it decreases frequency to the set value.

Set the speed reference value to form a curve at the start and end cycle of the acceleration and deceleration curves. If it is set higher, linear zone gets smaller.

H17 sets the starting and H18 the ending ratio between S-curve and Linear in ½ of Accel/Decel Ref. Frequency. For smooth Accel/Decel starting, increase H17 or H18 to extend the S-curve ratio.

Note that setting Frequency Ref. for Accel/Decel (H70) is set to Max Freq and target freq is set below Max freq. the shape of the S-curve may be distorted.
