•

profile.
•
Cleared (0) - Configures the PTO instruction to produce a Trapezoid
profile.
PTOX Idle Status (IS)
The PTOX IS (Idle Status) is controlled by the PTO sub-system. It can be
used in the control program by an input instruction. The PTO sub-system
must be in an idle state whenever any PTO operation needs to start.
The IS bit operates as follows:
•
Set (1) - PTO sub-system is in an idle state. The idle state is defined
as the PTO is not running and no errors are present.
•
Cleared (0) - PTO sub-system is not in an idle state (it is running)
PTOX Error Detected (ED)
The PTOX ED (Error Detected Status) bit is controlled by the PTO
sub-system. It can be used by an input instruction on any rung within the
control program to detect when the PTO instruction is in an error state. If
an error state is detected, the specific error is identified in the error code
register (PTOX:0.ER). The ED bit operates as follows:
•
Set (1) - Whenever a PTO instruction is in an error state
•
Cleared (0) - Whenever a PTO instruction is not in an error state
