NOTE
• During acceleration/deceleration, the frequency within the set area is valid.
• If the setting ranges of individual groups (1A and 1B, 2A and 2B, 3A and 3B) overlap, Parameter write error (Er1) occurs.
• If a jump frequency that exceeds the setting of Pr.1 (Pr.18) Maximum frequency 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 Minimum frequency,
the jump frequency is the set frequency. (The set frequency can be equal to or less than the frequency lower limit.)
Example when the frequency upper/lower limit the jump areas.
