[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.
Parameter Number 56
Parameter Type Read and Write
Display Units / Drive Units 0.1 Second / Seconds x 10
Factory Default 0.0 Sec
Minimum Value 0.0 Sec
Maximum Value 3000.0 Sec
[Language]
This parameter selects between English and the
alternate language (not currently available) for the
HIM display.
Parameter Number 47

“English” 0
“Alternate” 1
[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.
Parameter Number 77

“Slip Comp” 1 Slip compensation
“Speed Droop” 2 Negative slip compensation
“PLL” 3 Phase lock loop
“Encoder Fdbk” 4 Encoder feedback–closed loop
“Droop + Reg” 5 Enc. fdbk.–closed loop w/ active droop
“P Jump” 6 Traverse function
[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.
