Cam Axis Position At Cam Control Switching - Mitsubishi Electric MELSERVO-MR-J4 GF Series Instruction Manual

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.
