(Note-1): The position command is the command unit set in the fixed parameter.
(f) Gain changing command, PI-PID switching command, control loop changing
command.
1) VC
series
Gain changing command and PI-PID switching command are available.
Control loop changing command becomes invalid.
2) VPH series
QDS
Gain changing command is available.
PI-PID switching command and control loop changing command
become invalid.
(g) Driver communication
QDS
The driver communication is not supported. If the driver communication is
set in a servo parameter, a major error (error code: 1363) will occur when
the power of Multiple CPU system is turned ON.
