ASDA-A3
Virtual master axis
During E-Cam operation, if there is a phase lead or phase leg in the slave axis, use the virtual
master axis to correct the cam phase. Virtual master axis operation is as shown in Figure
7.3.10.1.
Use P2.077 to set the virtual master axis function.
P2.077.X can mask the actual master axis pulses and determine how the virtual master axis
pulses are generated, as shown in the following table.

Description
Slave axis is driven by the actual master axis
pulse.
Slave axis stops operating, but the masked
master axis pulse continues to be stored in the
internal variable.
Command source is the virtual pulse frequency
(unit: Kpps) set in P2.077.UZ. This function
continues to operate. To stop the virtual pulse,
set X to 1.
Command source is the virtual pulse number
(unit: pulse) set in P2.077.UZ. This function
only refers to the pulse number set in
P2.077.UZ.
-
Slave axis is driven by the actual master axis
pulse and the master axis pulse continues to be
stored in the internal variable.
Command source is the frequency transmitted
by the actual master axis (P5.088.Y) plus the
virtual pulse frequency (unit: Kpps) set in
P2.077.UZ. This function continues to operate.
To stop the virtual pulse, set X to 9.
Command source is the pulse transmitted by
the actual master axis (P5.088.Y) plus the
virtual pulse number (unit: pulse) set in
P2.077.UZ. This function is often used for
dynamic adjustment.
