parameters P3809.B (start/stop forward rotation) and P3824.B (start/stop reverse rotation) are
effective when they are changed from 0 to 1 (valid at rising edge). The running direction of the
frequency converter is subject to the parameter set first among these two parameters.

4. Three-wire mode 2. The parameters P3809.B, P3811.B and P3845.B are used to control the
forward and reverse rotation of the motor, enable and disable the running.
In this control mode:
When the parameter P3845.B (frequency converter running prohibited) is 0, the frequency
converter stops. During the start and operation of the frequency converter, the value of
parameter P3845.B (frequency converter running prohibited) must be kept at 1. The
parameters P3809.B (start/stop forward rotation) is effective when they are changed from 0 to
1 (valid at rising edge). The running direction of the frequency converter is subject to the
parameter P3811.B (reverse rotation command).
