Description
The VFD can quickly slow down the motor by
increasing the magnetic flux. The energy
generated by the motor during braking can be
transformed into heat energy by increasing the
magnetic flux.
The VFD monitors the state of the motor
continuously even during the magnetic flux
period. Magnetic flux braking can be used for
motor stop, as well as for motor rotation speed
change. The other advantages include:
Braking is performed instantly after the stop
command is given. The braking can be started
without waiting for magnetic flux weakening.
This will have better motor cooling effect.
During the magnetic flux braking period, the
stator current of the motor increases while the
rotor current does not, and the cooling of the
stator is much more effective than that of the
rotor.
This function code is used to adjust the current
display value on the AC input side.
0.00–1.00
0: Lock upon STO alarm
Lock upon STO alarm: indicates resetting is
required after state restoration if STO occurs.
1: No lock on STO alarm
No lock on STO alarm indicates STO alarm
disappears automatically after state restoration
if STO occurs.
