Virtual Servo Amplifier Function

This function executes the operation virtually without connecting servo amplifiers (regarded as connected). The synchronous
control with virtually input command is possible by using the virtual servo amplifier axis as servo input axis of synchronous
control. Also, it can be used as simulation operation for axes without servo amplifiers.
Control details
• When "4097, 4128" is set in "[Pr.100] Servo series" set in the flash ROM, it operates as virtual servo amplifier immediately
after power supply ON.
• When "0" is set in "[Pr.100] Servo series" set in the flash ROM, it operates as virtual servo amplifier by setting "4097, 4128"
in "[Pr.100] Servo series" of buffer memory and by turning the "[Cd.190] PLC READY signal" OFF to ON after power supply
ON.
• Do not connect the actual servo amplifier to axis set as virtual servo amplifier. If the servo amplifier is connected, the LED
display status remains "Ab." and the servo amplifier is not recognized. The following servo amplifiers cannot be connected
until the end station.
• The feed current value and machine feed value of virtual servo amplifier are as follows.
• When the absolute position detection system is invalid, both the feed current value and machine feed value are set to "0".
• When the absolute position detection system is valid, the address at the latest power supply OFF is set if the home position has been established. If the
home position has not been established, the both of feed current value and machine feed value are set to "0".
• When the virtual servo amplifier is set in the system setting of the engineering tool, "0: Disabled (incremental system)" is set
in "Absolute position detection system (PA03)". Set "1: Enabled (absolute position detection system)" to the buffer memory
to use as absolute position system.
Do not make to operate by switching between the actual servo amplifier and virtual servo amplifier. When a
value except "0" is set in "[Pr.100] Servo series" set in the flash ROM, the connected device is not changed
even if the "[Pr.100] Servo series" of buffer memory is changed after power supply ON and then the "[Cd.190]
PLC READY signal" is turned OFF to ON. To change the connected device, write to the flash ROM and turn
the power ON again or reset the CPU module.
