Pulse Outputs
Section 5-2
Movement Direction when Using Absolute Pulse Specification
When operating with the absolute pulse specification, the movement direction
is selected automatically based on the relationship between the pulse output
PV when the instruction is executed and the specified target position. The
direction (CW/CCW) specified in an ACC(888) or SPED(885) instruction is not
effective.
Using CW/CCW Limit Inputs for Pulse Output Functions Other than Origin Searches
Pulse outputs will stop when either the CW or CCW limit input signals turns
ON. It is also possible to select whether or not the established origin will be
cleared when a CW or CCW limit input signal turns ON for an origin search or
other pulse output function.
S-curve Acceleration/Deceleration
S-curve acceleration/deceleration can be used for pulse output instructions
involving acceleration/deceleration. When there is leeway in the maximum
allowable speed, S-curve accelerations/decelerations will help control shock
and vibration by reducing the initial acceleration rate in comparison with linear
acceleration/deceleration.
Note
The setting for S-curve acceleration/deceleration applies to all pulse outputs.
