The SVR is used in the following two applications.
• Program testing: Results are easily obtained without mounting a motor.
• Generating commands: If the SVR is used in applications where motion modules are
required only for generating commands, such as master axis for phase control or multi-axis
synchronous control, then Motion Modules on real axes are no longer required.
The following table lists application examples of the SVR.
Electronic cam or shaft operation can be achieved by using the SVR for the virtual
master axis.
Multi-axis synchronous control can be achieved by controlling the SVR from a
motion program and then using the ladder program to copy position commands of the
SVR to other axes.
If the motion program is used to perform circular interpolation with the SVR, the axis
will operate with a sine curve command.
The software limit function and machine lock function cannot be used with the SVR. The position
error will always be 0.
The following figure shows an example system configuration using SVR.
