156 Using High-Speed Outputs
• Set (1) - Whenever a PTO instruction outputs a Jog Pulse
• Cleared (0) - Whenever a PTO instruction exits the Jog Pulse state
PTOX Jog Continuous (JC)
The PTOX 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 PTOX 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.
PTOX Jog Continuous Status (JCS)
The PTOX 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:
TIP
The output (jog) pulse is normally complete with the JP bit set. The JPS bit
remains set until the JP bit is cleared (0 = off).
