Description
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 immediately after the stop
command is given. The braking can be started
without waiting for magnetic flux weakening.
The cooling is better. The current of the stator
other than the rotor increases during magnetic
flux braking, while the cooling of the stator is
more effective than the rotor.
This function code is used to adjust the current
display value on the AC input side.
0.00–1.00
0.00 Hz–P00.03(Max. frequency)
Note: Valid only for torque control.
0: No limit on acceleration or deceleration
1: ACC/DEC time 1
2: ACC/DEC time 2
3: ACC/DEC time 3
4: ACC/DEC time 4
0: Disable
1: Enable
Note: When the VFD detects that the heatsink
temperature exceeds the rated temperature, it
automatically decreases the carrier frequency to
lower the temperature rise. When the
temperature decreases to a specified value, the
carrier frequency restores to the setting. This
function can reduce the VFD overheat alarm
reporting chances.
