6.1.2 Parameter list
The virtual servomotor parameters are shown in Table 6.1 and the parameters shown
in this table are explained in items (1) to (4) below.
Refer to the help of MT Developer for the parameter setting method of virtual
servomotor.
A parameter is requested except for the above for program operation of the virtual
servomotor. Refer to the item (5) for precautions of the parameter blocks.

(1) Virtual axis No. setting
The virtual axis No. is set in the servo program at the virtual mode operation. The
axis No. of the virtual servomotor connected to the virtual main shaft or virtual
auxiliary input axis.
(2) Upper/lower stroke limit value settings
The stroke limit range of the virtual servomotor axis is set.
(a) When the stroke limit value is made valid:
Set the stroke range of the "Lower stroke limit value < upper stroke limit
value".
The stroke limit check and control details at the start/during start are shown
below.
