The main use procedure of the speed control mode is as follows:
1. Connect the power cables of the main circuit and control circuit of the servo drive, motor
power cables, and encoder cables correctly. After power-on, the keypad of the servo drive
displays "rdy", indicating that the wiring is correct.
2. Perform trial jog running by pressing keys and ensure that the motor can run properly.
3. Connect the required DI/DO signals and analog speed references of terminal CN1
according to Figure 4-6.
4. Perform the setting related to the speed control mode.
5. Make the motor rotate at a low speed and ensure that the rotating direction is normal.
Then, adjust the gain. For details, see the commissioning procedure in section 4.5.
