VFD500 high performance vector control frequency inverter user manual
0：SVPWM
It is normally used
1：SVPWM+DPWM
Using this modulation method can reduce the
switching loss of the inverter and reduce the
probability of overheating alarm of the
inverter; however, the electromagnetic noise
of the motor in the medium speed section will
be too large.
2：PWM at random
The electromagnetic noise generated by the
motor is white noise, not a sharp squeak.
3：SPWM
It is only used in special situation
10%～100%(modulation percentage)
When P22.06 is set to 1, increasing this
setting vaule can reduce the electromagnetic
noise in the middle speed section.
50%～110%
It is used to define the duty cycle of the
inverter side IGBT. Overmodulation is allowed
when it is set to 100% or more, and the
allowable overmodulation is deepened when
the set value is increased from 101 to 110.
0:diabled
1:enabled
When the AVR function is enabled, the effect
of the DC bus voltage change on the output
voltage can be eliminated.
0-Disabled
1-Enabled
2-only enable when ramp to stop
This parameter is only used to control the
built-in brake unit. For models without a built-
in brake unit, this setting can be ignored.
320V～400V(220V level )
600V～800V(380V level )
690V～900V(480V level )
950V～1250V(690V level)
0:No Operation
1:Output phase switch
(equal to change Phase between V and W,For
closed loop control, you need to re-rotate the
self-learning to confirm the encoder direction)
0:Effective when running
1:Forced control( effective when power on)
2:Adjustable as per drive temperature
0-G type;1-P type
G means normal duty (constant torque
➢
load)
P means light duty such as fan and
➢
pump
Read only Unit:0.1kw
Read only Unit:V
Read only Unit:0.1A
After this time, the inverter will stop and report
Er.TTA fault; if set to 0, it will be cancelled.
