3.6.2 Start Mode
The PE6000 supports three start modes, namely, direct start, rotational speed tracking restart,
and pre-excited start (asynchronous motor), set in P6-00.
P6-00 = 0 (direct
shown in the following figure. DC braking before the start is applicable to drive of load such as
elevator and crane. Startup frequency is applicable to drive with burst start under start torque, such
as cement mixer.

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.

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.
