A significant portion of the CHE100 manual is dedicated to safety, categorizing risks into "WARNING" and "CAUTION" levels to prevent injury or equipment damage. It provides:
OC1 / OC2 / OC3 (Overcurrent): Check for a motor short circuit, heavy mechanical load, or if the acceleration time (P0.11) is too short.OV1 / OV2 / OV3 (Overvoltage): Often occurs during rapid deceleration. Increase deceleration time (P0.12) or install a braking resistor.UV (Undervoltage): Check the input power supply for stability or a loose connection.OL1 / OL2 (Overload): The motor or drive is being pushed beyond its current rating. Check for mechanical jams or reduce the load.OH (Overheat): Ensure the cooling fan is running and that there is sufficient airflow around the heat sink. Safety Precautions
Provides a stable 10V DC power source for an external speed-potentiometer (typically 1 k Ωcap omega Ωcap omega
Initiates drive operation if keypad control mode is active. invt che100-0r7g-s2 manual
: Designed to handle 160% of its rated current for up to one minute.
The manual for the INVT CHE100-0R7G-S2 is well-organized and structured, making it easy to navigate and understand. The manual is divided into the following sections:
: 150% of rated current for 60 seconds; 180% for 10 seconds. Installation and Environmental Requirements A significant portion of the CHE100 manual is
Refer to the "Fault diagnosis and solutions" section if the keypad displays error codes like "OC" (Overcurrent) or "OV" (Overvoltage). 🔗 Manual Downloads
| 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. |
High Voltage Warning: After powering off the drive, wait at least 5 minutes for the DC bus capacitors to discharge before touching any terminals.No Capacitors: Never connect capacitors or surge absorbers to the output (U, V, W) terminals.Phase Insulation: Before connecting the motor, use a megohmmeter to ensure the motor phase-to-ground insulation is intact. Check for mechanical jams or reduce the load
