Maximum frequency, upper frequency limit and lower frequency limit should
be cautiously set base on the nameplate parameter of actual control motor and
the need of the running conditions.
Except of upper limit and lower limit, the output frequency while inverter
running are limited by the parameterized value of the start-up frequency、
free stop frequency、 close up DC braking initial frequency、 jump frequency
and so on. The relationships between the maximum frequency 、upper frequency
limit and lower frequency limit is shown as the follow fig.
Attention: the lower frequency limit range is invalid for jog frequency
operation. Only the upper frequency limit range is valid for the jog frequency
operation.
If the lower frequency operation mode [E-12] is "0", when actual given
frequency is lower than lower frequency limit, frequency inverter operation
as 0.00Hz. If the lower frequency operation mode [E-12] is "1",when actual
given frequency is lower than lower frequency limit, frequency inverter
operation as lower frequency limit.
