11.1.3 Virtual servomotor
The virtual servomotor is used to operate the virtual axis with the servo program or
JOG operation.

7 Operation mode during error Intermittent Intermittent/clutch OFF
11.1.4 Synchronous encoder
The synchronous encoder is used to operate the virtual axis with pulses input from the
external encoder (A, B phase type can be connected; serial type cannot be
connected).

11.1.5 Virtual axis
The virtual axes include the virtual main shaft and virtual auxiliary input axis. The
rotation of the drive module is conveyed to the conveyance module.
There are no parameters to be set for the virtual axis.
11.1.6 Gears
The gears are used to convey, to the output shaft, the number of pulses obtained by
multiplying the movement amount (number of pulses) of the drive module (virtual
servomotor, synchronous encoder) by the gear ratio set in the gear parameters, and to
determine the output shaft rotation direction.
