Set the time for pre excitation of asynch-
ronous motor at startup. This parameter can 
be established before starting the motor
magnetic field can effectively improve the 
starting performance of the motor and reduce 
the starting current and starting time.

Startup frequency

0.00 60.00Hz

It refers to the initial output frequency 
when the frequency converter is started. 
Setting a suitable starting frequency can 
have a higher starting torque, and for some 
static loads with larger static friction, 
some impulse can be obtained at the moment
of starting. However, if the set value is 
too large, OC1 and other faults may occur 
sometimes.
