[FUN 33] (DC Injection Braking Frequency) is the
frequency at which the inverter starts to output DC
voltage during deceleration.
[FUN 34] (DC Injection Braking On-Delay Time) is
the inverter output blocking time before DC injection
braking.
[FUN 35] (DC Injection Braking Time) is the time
the DC current is applied to the motor.
[FUN 36] (DC Injection Braking Voltage) is the DC
voltage applied to the motor and is based upon rated
inverter output voltage.

This function is used to maintain the motor speed
constantly. To keep the motor speed constant, the
output frequency varies within the limit of slip
frequency-FUN 38 [Rated slip] according to the load
current. For example, when the motor speed
decreases below the reference speed (frequency) due
to a heavy load, the inverter increases the output
frequency higher than the reference frequency to
increase the motor speed. The inverter increases or
decreases the output by delta frequency shown
below.
Output frequency = Reference freq. + Delta freq.

Description:
[FUN 41] selects the inverter capacity. Inverter
capacity must be set correctly for proper current
calculation and protective functions.
