Selecting Functions 5-17
5
Frequency limiter (High)
Frequency limiter (Low)
•
Set the upper and lower limits of the
frequency setting.
Setting range: 0 to 400 Hz
F16
F15 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).
F18
DC brake (Starting frequency)
DC brake (Braking level)
DC brake (Braking time)
•
Starting frequency: Set the frequency at
which the DC brake starts operation during
deceleration and stop.
Setting range: 0.0 to 60.0 Hz
•
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
VXSM75-1/550-3.
•
Braking time: Set the operation time of DC
braking.
Setting range: 0.0 Inactive
0.1 to 30.0 s

*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.
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.
F17
CAUTION
The brake function of the inverter
does not insure the function of a
mechanical latch.
Injuries could occur.
