6.3 Switching the C-863.12 On
The C-863.12 is intended for closed-loop operation with incremental position sensors (servo
mode On). After switch-on, open-loop operation is active by default (servo mode Off).
➢ Query the current operating mode with the SVO?, #4 or SRG? commands.
➢ Activate closed-loop operation with the SVO command.
➢ If necessary, program a startup macro that starts the C-863.12 via the SVO command in
closed-loop operation; see "Setting up a startup macro" (p. 106).
➢ Avoid motion in open-loop operation.
