F15
Frequency limiter (High)
F16 Frequency limiter (Low)
 Set the upper and lower limits of the frequency
setting.
Setting range: 0 to 400 Hz
*The starting frequency is output when the inverter
starts operation, and the stopping frequency is
output when it stops operation.
*(Low limit) > (High limit) ... Priority is given to the
High limit value.
F17 Gain (Frequency setting signal)
◆ Set the ratio of the frequency setting in relation
to the analog input.
The operation is as shown in the figure below.

F18 Bias frequency
This function obtains the frequency setting from
addition of the frequency setting in relation to
the analog input and a bias frequency. The
operation is as shown in the figure below.
However, if the bias frequency is larger
(smaller) than the maximum frequency (-
maximum frequency), the limit is set at the
maximum output frequency (- maximum output
frequency).

F20
 Starting frequency: Set the frequency at which
the DC brake starts operation during
deceleration and stop.
Setting range: 0.0 to 60.0 Hz
F21
 Braking level: Set the output current level during
DC braking. The level can be set in an
increment of 1% of the rated inverter output
current.
Setting range: 0 to 100%
Actual minimum level is fixed to 5% even if this
function set from 1 to 5% for 5.5/7.5E11S-4EN.
F22
 Braking time: Set the operation time of DC
braking.
Setting range: 0.0 Inactive
0.1 to 30.0 s

CAUTION
The brake function of the inverter
does not insure the function of a
mechanical latch.
Injuries could occur.
