Torque upgrade
This parameter can make compensation for output voltage when
converter is running in a low frequency, so that the characteristics of low-
frequency torque which is controlled by V/F can be compensated and
upgraded.
If the setting of torque upgrade is too high, not only motor tends to be
overheated but also over current may be caused by it. In general, the setting
of torque upgrade must be no more than 10%. To prevent converter from over
current effectively, this parameter must be adjusted properly. This parameter
should be increased whenever there is heavy load; otherwise, please
decrease this parameter.
• The practical slip of motor varies from load to load. Output frequency can
be adjusted automatically according to the condition of loading by this
functional parameter, so that compensation can be made for the influence of
load on rotational speed of motor.

Slip
compensation
• AVR function is also known as Automatic Voltage Regulation function.
Adjustment will be made automatically to stabilize output voltage whenever
there is fluctuation of input voltage, so that it can prevent converter from
overheat of motor caused by high output voltage or poor performance
caused by low output voltage.

Energy-efficient
running
• During the process of no-load or light-load running, output voltage can be adjusted
properly to achieve automatic energy conservation by detecting load current. This
parameter is applicable to the load of draught fan or pump.
• Multiple-phase V/F curves can be defined by these six parameters
above (P4-01~ P4-06)
The set value of V/F curves is generally set according to the load
characteristics of motor.

Precaution : motor may be overheated or even burned if preset low-

5 : Self-adaptive control can be applied to running regulation by adapting itself to actual
load automatically, which is applicable to the operating situations which require greater
low-frequency torque as well as strict control on speed.
3 : high starting torque V/F is applicable to the operating situations which require higher
starting torque.
4 : Self-setting V/F indicates that V/F curve can be preset randomly by the functional
codes P4-01~P4-06, which is applicable to the operation with special load, for example
dewaterer or centrifuge, etc.
Parameters must be set correctly according to the information of nameplate on the motor
if this function needs to be enabled; it's only when the capacity of the motor is the same
as that of this converter can its performance be improved greatly.
