Motion Control
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.

P2.077.Y sets whether to write the pulse number of the virtual master axis to P5.087 (initial lead
pulse before engaged).
 When the setting of P2.077.Y is changed from 0 to 1, write the pulse number of the virtual
master axis to P5.087.
 When the setting of P2.077.Y is changed from 0 to 2, write the pulse number of the virtual
master axis to P5.087 and store in EEPROM as non-volatile data.
 When the setting of P2.077.Y is changed from 0 to 7, write the pulse number of the virtual
master axis plus the pulse number of one cycle to P5.087 and store in EEPROM as non-
volatile data. The value written to P5.087 has to be positive. When the pulse number of the
virtual master axis is negative, the system automatically makes it a positive number by
adding the master axis pulses of one or multiple cycles and then write this value to P5.087.
 The virtual master pulse number set in P2.077.UZ is hexadecimal. If selecting continuous
forward or reverse operation, the unit is Kpps. If selecting jog operation in forward or
reverse direction, the unit is pulse.

Slave axis operates based on the actual master
axis pulses.
Disable
Slave axis stops operating, but the masked
master axis pulse number continues to be
stored in the internal variable.
Command source is the virtual pulse frequency
set in P2.077.UZ (unit: Kpps). This virtual pulse
function continues to operate. To stop it, set X
to 1.
Enable
Command source is the virtual pulse number
set in P2.077.UZ (unit: pulse). This function
only refers to the pulse number set in
P2.077.UZ.

Slave axis operates based on the actual master
Disable axis pulses. The master axis pulse number
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 in Kpps set by
P2.077.UZ. This virtual pulse function
continues to operate. To stop it, set X to 9.
Enable
Command source is the pulse transmitted by
the actual master axis (P5.088.Y) plus the
virtual pulse number in pulses set by
P2.077.UZ. This function is often used for
dynamic adjustment.
