Note!
If the acceleration and deceleration times are set too short the controller may switch
off with TRIP OC5 under unfavorable service conditions. In these cases, the
acceleration and deceleration times should be set short enough so that the drive
can follow the speed profile without reaching I

S−shaped ramp setting
C0182 > 0.00: S–shaped (smooth) ramp function generator operation for the main setpoint.
·
The value of C0182 determines the shape of the S−curve.
·
C0182 has no effect on the additional setpoint (PCTRL1−NADD).

Note!
l The ramp function generator operation in the parameter sets must not differ as
C0182 is the same in all parameter sets.
l The S−shaped ramp also has an effect on the deceleration time for quick stop!
