8.7.1.2 Smooth start and quick stop of the drive
[8-29] Example: Smooth start and quick stop
 Tip!
Rapid deceleration (C01232/2
) reduces the time from releasing of the "jog button" to actual
stopping of the drive, with the result that it is easier to position the drive "by sight" and the
desired stop position is not passed.
8.7.1.3 Second speed
[8-30] Example: Change-over to second speed
 C01231/1: Manual jog: Speed 1
 C01232/1
: Manual jog: acceleration
 C01232/2
: Manual jog: deceleration
 C01233/1
: Manual jog: S-ramp time
• For accelerating and decelerating,
different values can be set in
C01232/1...2
so that smooth starting
and quick stopping of the drive can be
implemented.
• In order to reduce jerking, the two
ramps can be set in such a way that
they are s-shaped. This is done by
entering a relative S-ramp time in
C01233/1
.
