PTO Operating Frequency Status (OFS)
The PTO OFS (Output Frequency Status) is generated by the PTO
sub-system and can be used in the control program to monitor the actual
frequency being produced by the PTO sub-system.
PTO Total Output Pulses To Be Generated (TOP)
The PTO TOP (Total Output Pulses) defines the total number of pulses to
be generated for the pulse profile (accel/run/decel inclusive).
PTO Output Pulses Produced (OPP)
The PTO 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.

NOTE
The value displayed may not exactly match the value
entered in the PTO:0.OF. This is because the PTO
sub-system may not be capable of reproducing an exact
frequency at some of the higher frequencies. For PTO
applications, this is typically not an issue because, in all
cases, an exact number of pulses are produced.
