Reaction of the PTO channel to CPU STOP
The PTO channel reacts to a change to CPU STOP with the removal of the drive enable (to
the extent that the drive enable output is configured) and with output of the velocity setpoint
0 at the hardware outputs configured for the signal tracks A and B. The CPU STOP reaction
of the PTO channels cannot be configured.
Note
Reaction to CPU STOP
Upon CPU STOP, the hardware outputs assigned for the PTO outputs A and B can switch to
signal state 'High' (1) and/or remain the
re. A switching/remaining of the two hardware
outputs to/in signal level 'Low' (0) is not guaranteed.
Controller
The pulse output channels for the four modes of the pulse generators (PTO) are controlled
using Motion Control via the technology objects TO_SpeedAxis, TO_PositioningAxis and
TO_SynchronousAxis. With these operating modes, the control and feedback interface of the
channels is a partial implementation of the PROFIdrive interface "Telegram 3". For a detailed
description of the use of motion control and its configuration, refer to the S7-1500 Motion
Control function manual (http://support.automation.siemens.com/WW/view/en/109749262)
and the STEP 7 online help.
