The impact of 18-00 on the torque and the speed are shown in figure 4.3.101
Figure 4.3.101 18-00 Effect on the torque and speed
FOC (Flux Orient Control) delay time (18-05)
(1)
In the SLV mode, the slip compensation of the magnetic flux depends on the torque current
and excitation current.
(2)
If the motor load rises above 100% while running at the motor rated frequency, the motor
voltage and resistance drops sharply, which may cause the inverter output to saturate and
current jitter occur.
(3)
The magnetic flux slip compensation will independently control the torque current and the
excitation current to prevent current jitter.
(4)
For slow speed or fixed speed operation, 18-05 may be increased. For fast operation adjust
18-06.
Slip compensation gain (18-06)
If the motor is jittering at the rated frequency under full load, the value of 18-06 may gradually be
reduced to zero to reduce current jitter.
