12-10Precautions when Using Pulse Outputs
When operating with the absolute pulse specification, the movement direction (CW/CCW) 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, SPED or PLS2 instruc-
tion is not effective.
Pulse outputs will stop according to the PLC Setup when either the CW or CCW Limit Input Signals
turns ON. It is also possible to select whether or not the defined origin will be cleared when a CW or
CCW Limit Input Signal turns ON for a pulse output function.
The CP2E CPU Unit
’
s pulse output frequency is determined by dividing the source clock frequency
(15 MHz) by an integer ratio. Consequently, there may be a slight difference between the set frequency
and the actual frequency, and that difference increases as the frequency increases. The actual fre-
quency can be calculated from the following equations.
