Eaton EASY-E4 Series User Manual

6. Function blocks
6.1 Manufacturer function blocks
6.1.4.3 PO - Pulse output
General
The DC versions of easyE4 base devices provide 2 pulse output func-
tion blocks, PO01 through PO02. These function blocks make it pos-
sibly to quickly output 24 V pulses in order to drive stepper motors.
Pulse output PO01 is hardwired to device output Q1 and PO02 to
device output Q2.
If you use a PO function block with its hardwired device output
Q1 or Q2, do not not assign that device output again in the pro-
gram. Doing so will not have any effect, as a state change by
the function block has a higher priority.
WARNING
UNFORESEEABLE SWITCHING STATES AT OUTPUT
When using the PO function block, strictly observe the separate assign-
ment of the outputs if other hardware-dependent function blocks are
used, such as the PW function block.
If this is not observed, unforeseeable switching states may occur at the output con-
cerned.
