Sensorless Vector Control (SVC), V/f control, and torque control. Critical Parameter Settings
The manual explains the built-in LED keypad:
Sudden mechanical load changes, short circuits, or ground faults in the motor wiring.
: A vast list of codes for setting maximum/minimum frequencies, acceleration/deceleration times (0–3600 seconds), and PID control settings.
Programmable digital inputs for forward/reverse or multi-speed steps. invt che100-0r7g-s2 manual
The is an indispensable resource for any technician or engineer working with this drive. It provides all the necessary information, from basic safety and installation guidelines to advanced parameter configuration, communication setup, and troubleshooting.
: The inverter series (General-purpose sensorless vector and V/F control).
: Applications requiring rapid torque response and high speed accuracy.
| Fault Code | Meaning | Likely Cause for 0R7G-S2 | Manual Guidance | | :--- | :--- | :--- | :--- | | | 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 | Sensorless Vector Control (SVC), V/f control, and torque
: -10°C to +40°C (Derating required above 40°C). Cooling Method : Forced air cooling via built-in DC fan. Hardware Installation & Wiring
The control board handles external signals for starting, stopping, and speed adjustment.
