PTO Jog Continuous (JC)
The PTO JC (Jog Continuous) bit instructs the PTO sub-system to generate
continuous pulses. The frequency generated is defined by the Jog
Frequency parameter in the PTO function file. Jog Continuous operation
is only possible under the following conditions:
•
PTO sub-system in idle
•
Jog Pulse not active
•
Enable not active
The JC bit operates as follows:
•
Set (1) - Instructs the PTO sub-system to generate continuous Jog
Pulses
•
Cleared (0) - The PTO sub-system does not generate Jog Pulses
When the Jog Continuous bit is cleared, the current output pulse is
truncated.
PTO Jog Continuous Status (JCS)
The PTO JCS (Jog Continuous 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 is generating continuous Jog
Pulses. The JCS bit operates as follows:
•
Set (1) - Whenever a PTO instruction is generating continuous Jog
Pulses
•
Cleared (0) - Whenever a PTO instruction is not generating
continuous Jog Pulses.
