7.2.2 Pulse Output Function
For each pulse output mode and position control mode there are certain designated high-
speed counter channels, inputs and outputs.
NOTE
• The pulse output function is only available with the transistor output type.
• Linear and circular interpolation control is only available with CPU type
C32T2(TM) and C28P2(TM).

The home return operation of the interpolation axes should be performed for every channel (see page
145).
2)
Any input can be specified in the global variable list. The near home input is enabled/disabled using the
pulse output control code. See "
Writing the Pulse Output Control Code" on page 126.

Control flags and memory areas
Counter and pulse output settings as well as elapsed values are stored in special data
registers. The pulse output status is stored in special internal relays. To access special data
registers and special internal relays, use the PLC-independent system variables. You can
insert system variables directly into the POU body: Use the "Variables" dialog without entering
a declaration in the POU header. See "
Instructions and system variables" on page 124.
