R1 * Y1
0: no output
1: output
When the output functions of Y1 and R1 are set to “47: PLC output”, the output result
will be controlled by the corresponding bit of F03.31. 0 indicates no output and 1 indicates
that there is output.

F04.00=0: direct start
The inverter will be started at the starting frequency, following DC braking (no DC
braking in the case of F04.04=0) and pre-excitation (no pre-excitation if F04.07 is set to 0).
After the starting frequency duration expires, the inverter will run at the set frequency.
F04.00=1: start with speed tracking
The inverter is smoothly started from the current rotation frequency of the motor,
following the speed tracking (size and direction).

In order to ensure the motor torque during the start, please set the appropriate starting
frequency. To fully establish the magnetic flux during the motor start, the starting frequency
should be maintained for some time. The starting frequency F04.01 is not limited by the
lower frequency limit.
