F3 Function, Continuous Correction Pulse
The F3 function provides a continuous correction signal until the measured slip is less than the slip
setting. The F3 function is implemented by setting the correction pulse width to zero and the correction
pulse interval to zero or any non-zero number. The correction pulse is continuous (full-on) as long as the
slip frequency is greater than the slip setting. No corrections are issued if the slip frequency is less than
the slip setting. One exception would be to bump the target pulse if the slip frequency is very close to
zero. Figure 2-7 shows the F3 function correction pulse and slip frequency relationship.
