Torque start mode
Setting L52 data to "1" enables the torque start mode.
In this mode, the inverter increases the output voltage to generate torque along the slope specified by
the time (F24) in the rotation direction specified by a run command. When the detected speed
exceeds the starting speed (F23), the inverter starts the speed control to accelerate smoothly.
When F23 = 0.00, this mode is disabled.
In the torque start mode, a PG error may occur or the DSAG command on the
general-purpose output terminal may go OFF depending upon the starting speed setting.

In case of Torque Vector control
(i) When a multistep speed command with S-curve acceleration/deceleration is enabled (F01 = 0)
If the reference speed (pre-ramp) exceeds the starting speed, the inverter activates the DC braking
operation. After the DC braking operation, the inverter activates a soft start to the starting speed.
After starting speed holding time (F24) elapses, the inverter accelerates up to the reference speed
(pre-ramp).
