P3-18 is the speed configured for closed-loop inching operation, which only takes effect in two inching
modes, and the rest normal control modes are invalid.
(5) Run the servo system and confirm whether the full closed-loop system operates normally.
Send instructions through PLC and other upper devices to observe the operation of the servo unit.
Slowly increase from low speed to target speed and gradually confirm.

When the parameter is set to 0, the full closed-loop function is closed; when the parameter is set to
1, the full closed-loop function is opened, and the external encoder position signal is used for control.
Only when P9-00.0 full closed-loop function is opened, other related functions of P9-00 and P9-01
can work, otherwise, even the setting will be invalid. The opening of the full closed-loop function
requires the servo to be powered on again.

P9-00 shall cooperate with motor rotation direction parameter setting (P0-05) to decide whether to
change.
When the direction setting is wrong, when P9-02 is not set to 0, the alarm E-236 (alarm of
excessive deviation between motor and load position) will be output during operation, at this time,
shutting down the enable needs to be powered on again; if P9-02 is 0, the alarm E-237 (counter
direction reversed) will be output, and the value will be adjusted by power on again.
