Important: This parameter does not apply to the Jog Ramp Accel Time (P.021) or Jog
Ramp Decel Time (P.022) parameters.
The acceleration and deceleration times must be set the same for the S-Curve ramp
to function the same for acceleration as for deceleration. If the deceleration time is set
lower than the acceleration time, the deceleration time specified may not be met.
P.019 S-Curve Enable
When S-Curve
accel/decel is
selected, the accel or
decel ramp time
begins and ends
slowly, creating an
S-Curve function.
Refer to figure 4.5.
For V/Hz regulation,
this parameter is
always set = ON.
Parameter Range: OFF = Use linear accel/decel function
ON = Use S-Curve accel/decel function
Default Setting: ON (V/Hz)
OFF (vector)
Parameter Type: Configurable
Refer also to parameters: P.001 Accel Time 1
P.002 Decel Time 1
P.017 Accel Time 2
P.018 Decel Time 2
