Programming

[S Curve Time]

This creates an adjustable s curve ramp. If S Curve
Time is < the programmed accel/decel time, the
actual ramp will be the sum of the two. If S Curve
Time is

the programmed accel/decel times, a fixed

S curve will be created whose time is double the
programmed accel/decel time.

[Speed Control]

This parameter selects the type of speed modulation
active in the drive.

This parameter cannot be changed while the drive is
running.

Important: If encoder feedback closed loop speed
regulation is required, “Encoder Fdbk” must be
selected.

[Flying Start En]

This value enables the flying start function and
chooses the method to be used. The drive will first
search from the direction it was last running.

ATTENTION: The “Speed Search” selection should not be
used with synchronous or permanent magnet motors. Motors
may be demagnetized during braking.

!

[FStart Forward]

This value sets the frequency at which the forward
speed search begins. If this value exceeds
[Maximum Freq], speed search will begin at
[Maximum Freq]. Forward search ends at zero Hertz
or when motor speed is found.
