It seems you’re looking for a feature (or a list of features) of the inverter model INVT CHE100-0R7G-S2, likely from its manual.
Based on the INVT CHE100 series manual (often titled CHE100 Series High-performance Vector Control Inverter), here are the key features for that specific model (0.75kW, 220V single-phase input):
Before diving into the manual, let’s decode the model number, as the manual refers to these specifications constantly:
| Code Section | Meaning | Interpretation | | :--- | :--- | :--- | | CHE100 | Product Series | INVT’s basic vector control VFD series | | 0R7 | Power Rating | 0.75 kW (approx. 1 HP) | | G | General Purpose | Suitable for constant torque loads (conveyors, mixers) | | S2 | Input Voltage | Single-phase, 200V–240V AC input (output is 3-phase) |
Critical Note from the Manual: The output of the CHE100-0R7G-S2 is three-phase 220V. It is designed to control a three-phase induction motor, not a single-phase motor. Attempting to run a single-phase motor without derating will damage the drive.
The control terminal logic (PNP vs NPN) is explained in the manual. Connecting a PLC output incorrectly can damage the drive’s 24V internal supply.
