3-6-4 Origin Compensation and Origin Shift
H Functions

pensation or origin shift.
Origin Compensation
Press the ADJ switch in SET mode to set the present angle at that point to zero. If an origin com-
pensation value has been set, the present angle will change to that origin compensation value. This
value (the origin position after compensation for the Resolver’s electrical 0°) will not be lost even if
the power is turned OFF.
Origin Shift
Turn ON the origin shift input (TRIG) in RUN mode to set the present angle at that point to zero. If an
origin compensation value has been set, the present angle will change to that origin compensation
value. This value will be lost if the power is turned OFF.
Origin shift is used during normal operation when the present angle (origin) is to be changed.

pensation value is enabled once the power has been turned ON again. If origin compensation
or origin shift are executed without the power being turned OFF and then ON again, the origin
compensation or origin shift function will not be executed properly.
lost when the power is turned OFF. The present angle after the power is turned ON again will,
therefore, be different from the present angle before the power was turned OFF and the cam
output timing will be out of synch. When using origin shift, stop the machinery and turn ON the
power supply while the START input is OFF. Execute origin shift at the correct position and
then turn ON the START input and start the machinery operation.
