Functional Description
CG Drives & Automation, 01-5326-01r3b
Acceleration Ramp Type [337]
Sets the type of all the acceleration ramps in a parameter set.
See Fig. 85. Depending on the acceleration and deceleration
requirements for the application, the shape of both the
ramps can be selected. For applications where speed changes
need to be started and stopped smoothly, such as a conveyor
belt with materials that can drop following a quick speed
change, the ramp shape can be adapted to a S-shape and
prevent speed change shocks. For applications that are not
critical in this, the speed change can be fully linear over the
complete range.

Deceleration Ramp Type [338]
Sets the ramp type of all deceleration parameters in a
parameter set Fig. 86.

Start Mode [339]
Sets the way of starting the motor when a run command is
given.
Default:
Linear
Linear
0
Linear acceleration ramp.
S-Curve
1
S-shape acceleration ramp.
NOTE: For S-curve ramps the ramp times, [331] and
[332], defines the maximum acceleration and
deceleration rated, i.e. linear part of S-curve, just as for
the linear ramps. The S-curves are implemented so that
for a speed step below sync speed the ramps are fully
S-shaped while for larger steps the middle part will be
linear. Therefore will a S-curve ramp from 0 –sync speed
take 2 x Time while a step from 0–2 x sync speed will
take 3 x Time (middle part 0.5sync speed – 1.5sync
speed linear). Also valid for menu [338], Deceleration
ramp type.

The motor flux increases gradually. The
motor shaft starts rotating immediately
once the Run command is given.
Normal DC 1
After a Run command the motor will be
magnetised first and the stator resistance
is measured
.
Depending on the motor time
constant and the size of the motor it can
take up to 1.3 s before the motor shaft
starts to rotate.
This will provide better
control of the motor when starting.
