2. PROCEDURE FOR VIRTUAL MODE POSITIONING CONTROL
2 − 8
2.3.4 Control change (current value change & speed change)
When a control change is executed in the VIRTUAL mode, the drive module's feed
current value and speed will change.
Control changes are not possible for the output module.
The differences between control changes in the REAL and VIRTUAL modes are
shown in Table 2.4 below.

REMARK
(1) The [

] symbols used in Table 2.4 indicate the following.
•[
!
] : Setting/execution possible
•[∆] : Execution possible, but programming method is different
•[
×
] : Setting/execution impossible
(2) (Note): If the output module is a roller which uses a speed change gear, a
speed change can be executed by changing the speed change gear
ratio.
