Running
command
• P6-00 = 1 (Rotational speed tracking restart)
It is applicable to large-inertia load. The frequency curve in this mode is shown in the
following figure. If the load motor is still rotating due to the inertia when the AC drive
starts, this mode is used to prevent start overcurrent.

Running
command
• P6-00 = 2 (Pre-excited start)
It is applicable only to inductive asynchronous motor. The AC drive performs pre-
excitation before start, improving quick response of the motor and meeting the
requirements of short acceleration time. The frequency curve in this mode is shown in
the following figure.
