To ensure the drive lasts for many years, perform regular checks:
| Group | Name | Primary Function | | :--- | :--- | :--- | | | Basic Functions | Basic settings like control mode, command source, frequency limits, acceleration/deceleration times, and carrier frequency. | | P1 Group | Start and Stop Control | Configures start/stop behavior, including start mode, DC braking, and stop mode. | | P2 Group | Motor Parameters | Stores the motor's nameplate data for accurate performance. | | P3 Group | Vector Control | Parameters for fine-tuning the sensorless vector control (SVC) algorithm. | | P4 Group | V/F Control | Settings for the V/F curve and related parameters, used in V/F control mode. | | P5 Group | Input Terminals | Configures the function of the multi-function digital input terminals (S1-S4). | | P6 Group | Output Terminals | Sets the function of the relay (TA/TB/TC) and open-collector output terminals. | | P7 Group | User and Display | Contains user password settings and configures what parameters are shown on the keypad display during run and stop modes. | | P8 Group | Auxiliary Functions | Includes features like PID control, traverse operation, and simple PLC functions. | | PB/PD/PE Groups | Advanced/Factory | Reserved for advanced motor control tuning, protection settings, and factory-set parameters. Modifying these can cause abnormal operation. |
