DIGIVEX Little Drive Servoamplifier

PVD 3530 GB 01/2005
How the ramp operates:
The ramp input can either be the analog input instruction or the stimuli generator as shown below:
In the event that the input is analog, scaling is carried out by the input instruction product (V) * speed
range for 1V, the speed range for 1 volt can be found in the servo-control dialogue box.
Ramp activation is validated by the information “TORQUE=1” (enable torque activated).
Therefore, the ramp operates as soon as the zero torque information is unlocked and an operating
direction (CW or CCW) selected. When CW or CCW is deactivated, the motor decelerates
in
accordance with the pre-set ramp
which means that CW or CCW cannot be selected as
mechanical stops.
Important remarks:
-
When “TORQUE” is successively deactivated and reactivated, the speed is reduced to
zero prior to following the progression of the ramp.
-
The ramp function must be deactivated when a DLD with digital control is used to carry
out a check on the axis position.
