Resetting Trip Causes

Do not reset the inverter without addressing the issue that caused the trip. Resetting without solving the problem will lead to another trip.

To recover from a trip:

    Power Reset: Turn off the power (keep it off until the LED goes out). See Section 6.26.2 for details.
    External Signal Reset: Short circuit RES and CC terminals on the control panel and release.
    Panel Reset: Follow the steps (see below for details).
    Communication Reset: Refer to the communication device manual (as per Section 6.36).

Panel Reset Steps:

    Check if the LED shows a trip condition; if not, press MODE to display it.
    Press STOP and ensure ENT is displayed.
    If the cause is resolved, press STOP again to reset.

Note:

    If the trip is due to braking resistor overload (QNT), it cannot be reset for 20 seconds.
    If the trip is due to inverter (QN3) or motor (QN4) overload, it can be reset even within the cooling period (30 seconds for QN3, 20 seconds for QN4), but the inverter may trip again.
    For overheating (QJ), reset after allowing sufficient cooling time.

Warning: Frequently resetting the inverter can damage the motor and components.
