Chapter 1 Drive Configuration
In the two samples shown above, the motor was decelerating. The sweep function
and slope manipulation work the same if the motor was spinning at some
constant speed.
Flying Start - Sweep Dip A
This plot shows the effect of modifying P360 [FS Speed Reg Kp]. In this plot a
motor is spinning at some constant speed when the drive is issued a start
command and the sweep routine is started. Note the current dip when the
parameter is set to its lowest value and the drive has determined the frequency of
the rotating motor. See the next plot when this parameter set to its highest
setting.
Flying Start - Sweep Dip B
This plot shows the effect of modifying P360 [FS Speed Reg Kp]. In this plot a
motor that is spinning at some constant speed when the drive is issued a start
command and the sweep routine is started. Note the current dip when the
parameter is set to its highest value and the drive has determined the frequency of
