Megmeet MV600 Series - Start and Stop Control Parameters (Group P08)

161
P07.09~P07.15 are used to determine different V/F curves of motor 2 under different V/F control modes.
The same as P07.07 and P07.08.
The motor is under V/F control mode. When the motor can not run normally due to the oscillation,
increase this gain properly. The larger the gain is, the more obvious the suppression on the oscillation will
be. To avoid great effect on the V/F running, the gain value should be as small as possible while effective
motor oscillation suppression shall be ensured.
0: Disabled
1: Always enabled
2: Disabled only in deceleration situation
AVR means automatic voltage regulation.
Under the V/F control mode, when fast stop is need and there is no braking resistor, selecting “Disabled
only in deceleration situation” can remarkably reduce the possibility of over-voltage fault. If there is
braking resistor or the fast deceleration is not needed, please select “Always enabled”.
This function is applicable to the application of multiple drives driving the same load. It can realize the
uniform distribution of power.
When the load of some drive is heavier, the drive will automatically reduce the output frequency
according to the parameter set via this function to remove some load. During trial operation, this value
can be adjusted gradually from the small value.
6.9 Start and stop control parameters (Group P08)
Different start modes can be adopted for different applications.
0: Start from the startup frequency
The drive begins to run from the startup frequency P08.02 and accelerate to the set frequency after the
startup frequency retention time P08.03. If the motor is still rotating upon the startup of the drive, the
motor will be automatically braked to low speed before the acceleration.
