(8) Virtual axis current value in one revolution storage device (main shaft side)
(2 words)
This parameter is set if an address mode clutch has been set at the rotary table
main shaft side.

The reference position (0) for the virtual axis current
value in one revolution is set with the address clutch
reference position setting signal
(M3213+20n).

(a) The virtual axis current value in one revolution for the main shaft side of the
rotary table is stored in the set device.
(b) The following devices can be set as the virtual axis current value in one
revolution storage device.

(Note-1) : D800 to D1559 are devices dedicated to the virtual servo motor axes,
synchronous encoder axes and output module "cams" in the virtual
mode. The areas of the unused virtual servo motor, synchronous encoder
and cam axes are available for the user.
(Note-2) : The devices should be started with an even number.

(d) The address mode clutch is turned ON and OFF at designated addresses in
the virtual axis current value in one revolution range: 0 to (N

-1) PLS.
Therefore, set the value in the clutch ON/OFF address setting device within
the range 0 to (N
D
-1) PLS.
(e) The virtual axis current value in one revolution reference position "0" is set
by turning M3213+20n (address clutch reference setting signal) ON and
switching to the virtual mode.
This sets the virtual axis current values in one revolution for both the main
shaft and the auxiliary input shaft to "0".
If the switch to the virtual mode is made with M3213+20n turned OFF,
control continues from the virtual axis current value in one revolution that
was effective last time the virtual mode was in effect.
