    What to do if there is over-current during acceleration in INVT CHE100-2R2G-4 DC Drives?
    • G
      ginadanielsAug 20, 2025
      If the INVT DC Drive displays an over-current error during acceleration, it could be due to several reasons. There might be a short-circuit or ground fault at the inverter output, the load could be too heavy, the acceleration/deceleration time might be too short, the V/F curve might be unsuitable, or there could be a sudden change in load. To resolve this: * Inspect the motor for damage, worn insulation, or cable damage. * Increase the acceleration/deceleration time or select an inverter with a larger capacity. * Check and adjust the V/F curve, and also check the load.

      If your INVT DC Drive displays an inverter overload, it could be due to a heavy load, short acceleration/deceleration time, an unsuitable V/F curve, or the inverter's capacity being too small. Here's how to address it: * Increase the acceleration/deceleration time or choose an inverter with a larger capacity. * Check and adjust the V/F curve. * Consider selecting an inverter with a higher capacity.

    How to fix IGBT Ph-U fault in INVT CHE100-2R2G-4?
    • J
      james13Aug 25, 2025
      If the INVT DC Drive shows an IGBT Ph-U fault, it could be due to several reasons: the acceleration/deceleration time being too short, a fault in the IGBT module itself, malfunction caused by interference, or improper grounding. To address this: * Increase the acceleration/deceleration time. * Inspect external equipment and eliminate any interference.

    What causes over-voltage during acceleration in INVT CHE100-2R2G-4 DC Drives?
    • J
      Jennifer JohnsonAug 26, 2025
      If the INVT DC Drive shows an over-voltage error during acceleration, it could be due to a short deceleration time causing excessive regenerative energy from the motor, or the input voltage being too high. To fix this, you can: * Increase the deceleration time or connect a braking resistor. * Decrease the input voltage to stay within the specified range.

    Why is my INVT CHE100-2R2G-4 DC Drives showing motor overload?
    • M
      Melissa CainAug 28, 2025
      If the INVT DC Drive indicates a motor overload, it may be because the motor is driving a heavy load at low speed for an extended period, the V/F curve is not properly set, the motor’s overload protection threshold (PB.01) is incorrect, or there is a sudden load change. To resolve this: * Select a variable frequency motor. * Check and adjust the V/F curve. * Check and adjust PB.01. * Check the load.

    • T
      Timothy RyanAug 30, 2025
      If the INVT DC Drive displays a DC bus under-voltage error, it could be due to an open phase in the power supply, a momentary power loss, loose wiring terminals for the input power supply, or large voltage fluctuations in the power supply. Inspect the input power supply or wiring.

    • T
      twalkerAug 31, 2025
      If the INVT DC Drive shows an input phase failure, it could be due to an open phase in the power supply, a momentary power loss, loose wiring terminals for the input power supply, large voltage fluctuations in the power supply, or poor voltage balance between phases. Check the wiring, installation, and power supply.

    How to resolve rectify overheat in INVT CHE100-2R2G-4?
    • K
      keitholsonSep 2, 2025
      If the INVT DC Drive displays a rectify overheat error, it could be due to high ambient temperature, proximity to a heat source, cooling fan issues (stopped or damaged), obstructed ventilation, or a high carrier frequency. To solve this: 1. Install a cooling unit. 2. Remove any nearby heat sources. 3. Replace the cooling fan. 4. Clear any obstructions in the ventilation channel. 5. Decrease the carrier frequency.

    How to troubleshoot communication fault in INVT CHE100-2R2G-4?
    • M
      Mr. Clifford Fernandez MDSep 6, 2025
      If the INVT DC Drive displays a communication fault, it may be due to an incorrect baud rate setting, receiving incorrect data, or a prolonged interruption in communication. To solve this, set the proper baud rate and check the communication devices and signals.
