PTOX Total Output Pulses To Be Generated (TOP)
The PTOX TOP (Total Output Pulses) defines the total number of pulses
to be generated for the pulse profile (accel/run/decel inclusive).
PTOX Output Pulses Produced (OPP)
The PTOX OPP (Output Pulses Produced) is generated by the PTO
sub-system and can be used in the control program to monitor how many
pulses have been generated by the PTO sub-system.
PTOX Accel/Decel Pulses Independent (ADI)
The PTOX ADI (Accel/Decel Pulses Independent) bit is used to define
whether the acceleration and deceleration intervals will be the same, or if
each will have a unique value. When this bit is set (1), separate profiles
are used. When this bit is clear (0), the PTO will operate with the
deceleration profile as a mirror of the acceleration profile.
If separate acceleration and deceleration profiles are desired, you must
choose a long integer file number and a starting element. There must be
four long elements available in the file:
