WARNING

When the torque limit function is selected, an operation
may not match the set acceleration and deceleration time
or set speed. The machine should be so designed that
safety is ensured even when operation does not match
set values.
Otherwise accidents may result.

WARNING

The frequency may be stagnated / held constant when
using the automatically OU trip prevention and set the
frequency limit(Low) to the setting frequency or less.
Otherwise accidents may result.

This is a function for motor 1.
To obtain the motor torque most efficiently, the torque

vector control calculates torque according to load, to
adjust the voltage and current vectors to optimum
values based on the calculated value.

When 1 (Active) is set, the set values of the following

functions differ from the written values:

 F09 Torque boost 1
Automatically set to 0.0 (automatic torque boosting).
 P09 Slip compensation amount Slip compensation is

automatically activated.
When 0.0 is set, the amount of slip compensation for
the TWMC standard 3-phase motor is applied.
Otherwise, the written value is applied.

Use the torque vector control function under the

following conditions:

 There must be only one motor.

Connection of two or more motors makes accurate
control difficult.

The function data (rated current P03, no-load current

P06, %R1 P07, and %X P08) of motor 1 must be
correct.

When the standard TWMC 3-phase motor is used,

setting the capacity (function P02) ensures entry of the
above data. An auto tuning operation should be
performed for other motors.

The rated current of the motor must not be significantly

less than the rated current of the inverter. A motor two
ratings lower in capacity than the nominal applied motor
for the inverter should be used at the minimum
(depending on the model).

To prevent leakage current and ensure accurate control,

the length of the cable between the inverter and motor
should not exceed 164ft(50m).

When a reactor is connected between the inverter and

the motor and the impedance of the wiring cannot be
disregarded, use P04, "Auto tuning," to rewrite data.


If these conditions are not satisfied, set 0 (Inactive).
