If you are looking to optimize your industrial automation, the INVT CHE100-0R7G-S2 is a reliable workhorse. Known for its sensorless vector control, this inverter provides steady torque and precise speed regulation even at low frequencies. 1. Safety First
Before installation or maintenance, ensure you have reviewed the safety warnings in the official manual.
Warning: High voltage remains in the capacitor even after power-off. Wait at least 5 minutes before touching terminals.
Caution: Improper grounding can lead to equipment damage or electric shock. 2. Key Specifications Model: CHE100-0R7G-S2 Power Output: 0.75kW (indicated by "0R7G") Input Voltage: Single-phase 220V ("S2") The model number "0R7G-S2" breaks down its primary
Control Mode: Sensorless Vector Control (SVC) or V/F control 3. Quick Setup & Wiring
The terminal layout is designed for accessibility. Standard wiring includes: L, N: Main power supply input. U, V, W: Output to the motor.
Control Terminals: Support for multi-function inputs, analog speed signals, and relay outputs for status monitoring. 4. Common Parameter Settings
To get started, you will likely need to adjust these basic parameters using the digital keypad:
P0.01: Select the run command source (Keypad, Terminal, or Communication). P0.03: Set the maximum output frequency. P0.11 / P0.12: Acceleration and deceleration times. 5. Troubleshooting Tips
The inverter features a comprehensive fault protection system. If you see an error code on the LED display, here is what they generally mean:
OC: Overcurrent (check for motor overload or short circuits).
OV: Overvoltage (often occurs during rapid deceleration; consider adding a braking resistor). LU: Undervoltage (check your power supply stability).
