11.1 SVR Virtual Motion Module
This section gives an overview of the SVR Virtual Motion Module and describes the system configuration.
11.1.1 Overview
The Virtual Motion Module (SVR) is a Software Module that provides an interface for virtual axes that are not
actually connected to Servomotors.
The SVR is configured in the same way as the SVB Motion Module with fixed parameters, setting parameters,
and monitoring parameters, and can be accessed from application programs using I/O registers.
The SVR can be used to control up to 16 virtual axes in the high-speed scan control cycle.
If the SVR is not used, the MP2100/MP2100M processing time can be reduced by setting the Module Type for
SVR to UNDEFINED in the Module Configuration Window.
The software limit function, follow-up function, and machine lock function cannot be used with the SVR. The
position error will always be 0.
The following table lists example applications of the SVR.

Application Example
Master axis for phase Electronic cam or shaft operation can be achieved by using the SVR for the
control virtual master axis.
Multi-axis synchronous Multi-axis synchronous control can be achieved by controlling the SVR
control from a motion program and then using the ladder program to copy position
commands of the SVR to other axes.
Sine curve commands If the motion program is used to perform circular interpolation with the
SVR, the axis will operate with a sine curve command.
