Customized Functions
Function
Virtual axes Any axis can be specified for virtual axis operation without connecting
to a Servo Driver and Servomotor.
A virtual axis can be used as the input axis for the electronic gear func-
tion or the electronic cam function to enable using these functions with-
out using an external encoder.
Electronic gear This function synchronizes the operating axis to the input axis at a
(CONNECT) specified gear ratio.
The following options can be selected for the input axis: Virtual axis
present position, real axis position command value, real axis encoder
feedback input, MPG input, or sync encoder input.
The gear ratio can be changed during operation.

The functions described in this section have been added to the CS1W-
MC221-V1 and CS1W-MC421-V1. They are mainly divided into two catego-
ries: customized functions and the easy backup function.

Advantages
Can be used as the mas-
ter axis for electronic
gear or electronic cam
control. Enables opera-
tions such as position
compensation by inte-
grating a virtual axis.
• Can reduce the amount
of mechanical equip-
ment required.
• Can reduce the man-
hours required for
mechanical mainte-
nance.
