Despite your best efforts, you may encounter an outdated or missing manual. Here is what to do:
Warning: Do not use a manual from a different series (e.g., CHV100 or GD100). The parameter mapping is different and could cause unpredictable behavior.
The 0R7G-S2 has a 0–10V analog input on A1. The manual details how to use P4-00 (lower limit) and P4-01 (upper limit) to scale a 0–10V signal from a PLC or potentiometer.
This is the most-accessed section of the manual. Common codes for the 0R7G-S2: invt che100-0r7g-s2 manual
| Fault Code | Meaning | Likely Cause for 0R7G-S2 | Manual Guidance | | :--- | :--- | :--- | :--- | | E.oC1 | Overcurrent during acceleration | Acceleration time too short; motor short circuit | Increase P0-06; check motor winding resistance | | E.oU1 | Overvoltage during deceleration | Deceleration time too short; regenerative load | Increase P0-07; add braking resistor | | E.Lu1 | Undervoltage | Input voltage dips below 200V | Check mains supply; check for loose R/T terminals | | E.oH | Overheat | Heatsink temperature >85°C | Verify fan operation; clean dust; check ambient temp | | E.SC | Short circuit | Output U/V/W shorted or to ground | Disconnect motor; run VFD unloaded; test motor insulation |
After wiring, you must program basic parameters via the keypad. The manual lists these as mandatory:
| Parameter | Name | Recommended Value for 0.75kW Motor | | :--- | :--- | :--- | | P0-01 | Motor control mode | 0 (V/F control) or 1 (Sensorless vector) | | P0-03 | Max output frequency | 50.00 Hz (or 60.00 Hz for North America) | | P0-04 | Upper limit frequency | 50.00 Hz | | P1-00 | Motor rated power | 0.7 kW (or 0.75 kW depending on motor plate) | | P1-01 | Motor rated voltage | 220 V | | P1-02 | Motor rated current | Find value from motor nameplate (typical: 3.5–4.2A) | | P1-03 | Motor rated frequency | 50 Hz or 60 Hz | | P1-04 | Motor rated speed | e.g., 1420 RPM (for 4-pole 50 Hz) | Despite your best efforts, you may encounter an
Crucial safety note from the manual: After changing P1-02 (motor current), perform a motor auto-tuning (P0-38 = 1 for static tuning) to optimize vector control.
In the world of industrial motor control, the Variable Frequency Drive (VFD) is an indispensable tool. Among the myriad of options available, the INVT CHE100-0R7G-S2 stands out as a reliable, cost-effective solution for controlling single-phase input motors. However, even the most robust hardware is useless without proper documentation. The invt che100-0r7g-s2 manual is not just a booklet; it is the operational backbone for installation, parameter setting, fault diagnosis, and maintenance.
This article serves as a comprehensive companion to the official manual. Whether you have lost your original copy, need help interpreting a complex parameter, or are troubleshooting an error code, this guide will walk you through everything you need to know about the CHE100-0R7G-S2 manual. Warning: Do not use a manual from a different series (e
The manual includes a maintenance checklist to ensure long life of your 0R7G-S2:
| Interval | Action | | :--- | :--- | | Daily | Check LED display for faults; listen for unusual noise from cooling fan. | | Monthly | Clean dust from heatsink using compressed air; tighten main circuit terminals (R, T, U, V, W) to specified torque (1.2 N·m per manual). | | Annually | Measure DC bus voltage (if qualified); replace cooling fan if bearing noise is present; check control terminal screw tightness. | | 5 Years | Replace DC bus capacitors (electrolytic capacitors dry out).
