9 10 is the servo report "overload": 1, which may be a wiring error or defect; 2. The load is too large (or the motor is braked, and you didn't give DC24V power); 3. Drive failure.
400 is servo overvoltage, check the circuit voltage. This SGDV- 1R6A0 1A is a three-phase 220v, or a single-phase 220v can be used by changing Pn00B=0 100.
