Parameter
4.1
Torque Boost (P.0, P.46)
P.0
“
Torque Boost
”
P.46
“
Second Torque Boost
”
●
For an inverter controlled by V/F mode, when the motor starts up, since the output voltage of the
inverter is inadequate, the starting torque is usually inadequate.
In this case, the output voltage can
be improved by properly setting the torque boost (P.0), and thus a better starting torque can be
acquired.

•
If P.0=6% and P.19=220V, and when output frequency of the inverter is 0.2Hz, the output voltage
is:
•
If RT is
‘
on
’
, P.46
“
Second Torque Boost
”
is valid.
Note: 1. If the set value of P.0 is too high, it will result in the action of the current protection of the inverter or the
inverter will be disabled to start smoothly.
2. The Second Function is valid only when P.44
≠
99999.
3. RT referred in this paragraph is the name of

P.126~P.128. For
the wiring, please refer to section 2-5.
