Description of Function Codes
Group P6: Start/Stop Control
Function
Code
P6-00
0: Direct start
•
If the DC braking time is set to 0, the AC drive starts to run at the startup frequency.
If the DC braking time is not 0, the AC drive performs DC braking first and then starts to run at
the startup frequency. It is applicable to small-inertia load application where the motor is likely to
rotate at startup.
1: Rotational speed tracking restart
•
The AC drive judges the rotational speed and direction of the motor first and then starts at the
tracked frequency. Such smooth start has no impact on the rotating motor. It is applicable to the
restart upon instantaneous power failure of large-inertia load. To ensure the performance of
rotational speed tracking restart, set the motor parameters in group P1 correctly.
2: Pre-excited start (asynchronous motor)
•
It is valid only for asynchronous motor and used for building the magnetic field before the motor
runs. For pre-excited current and pre-excited time, see parameters of P6-05 and P6-06.
If the pre-excited time is 0, the AC drive cancels pre-excitation and starts to run at startup
frequency.
If the pre-excited time is not 0, the AC drive pre-excites first before startup, improving the
dynamic response of the motor.
Function
Code
P6-03
P6-04
To ensure the motor torque at AC drive startup, set a proper startup frequency. In addition, to
build excitation when the motor starts up, the startup frequency must be held for a certain period.
The startup frequency (P6-03) is not restricted by the frequency lower limit. If the set target
frequency is lower than the startup frequency, the AC drive will not start and stays in the standby
