Chapter 7 Motion Control Functions
Position Commands and Position Registers:
Five different types of position commands: Absolute, Incremental, Stop, Homing and Speed
commands.
After position command

DO signal: HOME is OFF
Cmd_E continuously output
Speed Cmd_O continuously output. After speed command is completed, it indicates
command that the speed reaches the setting value and the motor will not stop.
DO signal: CMD_OK is OFF
Enter PR at the first time ( Servo Off->
Servo On or other mode for entering PR
mode)
Note: The incremental position command performs accumulation according to the end of the
position command (Cmd_E). It is irrelevant to current motor position and command timing as
well.
