Parker 690+ series - PHASE INCH

Programming Your Application 1-71
690+ Series Frequency Inverter
PHASE INCH
When in Phase control, the Phase Inch
function block may be used to advance or
retard the relative position on the slave
axis with respect to the master axis. This is
achieved by feeding extra counts into the
position error calculator at a rate given by
RATE in units per second.
If Register Mode is enabled, the MARK OFFSET is also effected.
ADVANCE and RETARD are usually linked to operator controlled, momentary-action push
buttons.

Parameter Descriptions
ADVANCE
Range: FALSE / TRUE
While TRUE, counts are added to the error calculator at a rate give by RATE. Note: if both
ADVANCE and RETARD are TRUE then no action is taken.
RETARD
Range: FALSE / TRUE
While TRUE, counts are subtracted from the error calculator at a rate given by RATE.
RATE
Range: 0.0001 to 30.0000
The rate at which counts are added to the Error calculator. A rate of 0.05 with a system scaled in
revolutions would cause the drive to advance at a rate of 0.05 revolutions a second with respect
to the master.
RATE SCALE
Range: 0.001 to 30.000
This allows fine control over the inch rate by scaling the value of RATE.
Actual Rate = RATE x RATE SCALE
ACTIVE
Range: FALSE / TRUE
This diagnostic displays TRUE while Advance or Retard actions are active.
