PTO Jog Continuous (JC)
Sub-Element
Description
JC - Jog Continuous
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.

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.
