CONTROL (SDD)
Ramp function for the 1
st
and 3
rd
quadrants.
The acceleration time for positioning depends on the direction.
“A” corresponds to terminals 17/19 and “B”
corresponds to terminals 18/20 (with positive polarity).
Normally the directions are: A = flow P-A, B-T and B = flow P-B, A-T.
For quadrants 2 and 4, parameters D:A and D:B are used as the deceleration distance demand.

CONTROL (SDD)
This parameter is specified in mm.
The deceleration stroke is set for each direction of movement (A or B). The control gain is calculated internally
depending on the deceleration distance. The shorter the deceleration distance, the higher the gain. A longer
deceleration distance should be specified in the event of instability.
Parameter D:S is used as the stopping ramp when disabling the START signal. After disabling, a new target
position (current position plus D:S) is calculated in relation to the speed and is specified as a command value.
