In the following description, input/output signals from the four paths are
called group A (path 1), group B (path 2), group C (path 3), and group D
(path 4), respectively.
The name of an input/output signal used for PMC axis control always
contains a lowercase “g”, as in EBUFg. However, there is no such signal
as EBUFg. The actual signal names represented by EBUFg are EBUFA,
EBUFB, EBUFC, and EBUFD, which respectively correspond to signals
of group A (path 1), group B (path 2), group C (path 3), and group D (path
4).
(1) In parameter No. 8010, specify which DI/DO signal group (A, B, C,
or D) is to be used for PMC axis control on a per–axis basis.
When using the same group for simultaneously controlling two or
more axes, check that the settings of the parameters related to
feedrate (rapid traverse rate, acceleration/deceleration time
constant, diameter/radius, linear axis/rotation axis, etc.) are
identical for each axis to be controlled.
(2) To enable direct PMC axis control, set each control axis selection
signal (EAX1 to EAX4), that corresponds to an axis to be controlled,
to 1.
(3) Determine the operation.
The axis control command signals (EC0g to EC6g) specify the type
of operation. The axis control feedrate signals (EIF0g to EIF15g)
specify the feedrate. The axis control data signals (EID0g to
EID31g) specify the moving distance and other data.
