9.5.13 Cam axis position at cam control switching

The cam axis position is determined by the positional relationship of three values of "Cam axis current value
per cycle", "Cam axis standard position", and "Cam axis feed current value". When the control has been
switched to the cam control (bit 5 of Control DI2 (2D02h) is on), defining the positions of two of these values
restores the position of the remaining one value.
Cam axis one cycle current value
Cam axis feed current value
Cam standard position
The following table lists the parameters required to be set for the cam axis position restoration. Refer to
section 9.5.7 (4) for the settings.
