∗
The frequency for applying the
DC brake is set by parameter
P12 stop frequency.
∗
The DC brake time when
switching between forward run
and reverse run is fixed to 0.1
sec.
MAX. OUTPUT FREQUENCY and BASE FREQUENCY
(Parameter P15 and P16)
Used to set the maximum output frequency and base frequency.
(These parameters are valid only when "FF" is set in parameter P03)
[Parameter P15:
The maximum output frequency is set.]
Data setting range (Hz)
50.0 to 250
[Parameter P16:
The base frequency is set.]
Data setting range (Hz)
45.0 to 250
Note 1)
A frequency higher than the upper frequency clamp (parameter P54) cannot be
output.
Note 2)
Read the precautions given on page 66 when setting a value other than 50Hz or
60Hz.
ACCELERATION FREQUENCY HOLD (Parameter P17)
When the set acceleration time is too short for the inertial load, this parameter can be used to
temporarily reduce the acceleration rate to prevent an overcurrent trip.
