5-5 Cyclic velocity control (CV) command (Command code: 3
h)
In this velocity control mode, the host controller generates the command velocity and updates it (or transmits updated
command) at the communication cycle.
Upon receiving this command, the servo driver switches the internal control mode to velocity control.
For details of velocity control block diagram, refer to Technical Reference, SX-DSV02309”Section 5-2-2”,
Functional Specification.
When this command is received in Block Diagram of 2 Degrees of Freedom Mode, it causes the command error.
