Invt Che100-0r7g-s2 Manual [extra Quality]

For the CHE100-0R7G-S2's main wiring: connect single-phase 220V AC power supply lines to the R and S terminals, and connect the three-phase motor leads to the U, V, and W output terminals. For the control wiring, the manual details the function of each terminal. The digital input terminals (S1 to S4) can be programmed for various control functions via the inverter's parameters. The analog inputs (AI1, AI2) can accept 0-10V or 0-20mA signals for speed reference or PID feedback.

| Fault Display | Fault Name | Common Causes from Manual | Suggested Solution | | :--- | :--- | :--- | :--- | | | Over Current | Short circuit at the output; acceleration time too short. | Check motor insulation and cables. Increase Acc/Dec time (P1.02/P1.05). | | OU | Over Voltage | Deceleration time too short (regenerative energy); input voltage fluctuation. | Extend deceleration time or connect an optional braking resistor (Built-in braking unit available). | | OH1/OH2 | Overheat | Ambient temperature too high; Cooling fan failure; Carrier frequency too high. | Clean ventilation ducts, replace cooling fans, or lower the carrier frequency to reduce switching losses. | | CE | Communication Fault | Improper baud rate setting; RS485 wiring error or interference. | Check Modbus communication parameters and ensure shielded cables are used. | | -- | No Display | Power supply off or incorrect; Rectifier bridge failure (CHARGE light off). | Verify power at R/S/T terminals. If CHARGE LED is off, the internal rectifier may need replacement. |

The CHE100 utilizes a group-based parameter system. To enter programming mode, press the "PRG" key, use the arrows to find the group, and press "DATA/ENT" to modify. Essential Parameters for Startup
