Start control mode (L52)
The soft start is available in two start control modes: Speed start and torque start modes. L52 selects
the start control mode.

Soft start to the starting speed is disabled.
Once the inverter speed decreases to less than the stop speed, increasing the reference
speed (pre-ramp) with a run command being ON does not activate a soft start to the
starting speed. To soft start the motor up to the starting speed, turn the run command
OFF once.

In case of Vector control with PG
Speed start mode
Setting L52 data to "0" enables the speed start mode.
(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 a soft start to the
starting speed. After starting speed holding time (F24) is elapsed, the inverter accelerates up to the
reference speed (pre-ramp).
If stop speed set value (F25) is higher than starting speed set value (F23), the inverter
does not activate a soft start as long as the reference speed (pre-ramp) does not exceed
the stop speed.
