FAQ:

1. How to quickly export the historical fault records of ACS880-01-206A-3 through the operation panel or Drive composer software?

Operation panel export:

1. Clear the current fault and press the Menu key to enter the event record to view historical faults.
2. When paired with a Bluetooth control panel, use the Drivetone APP on your mobile phone to create and export a support package containing fault records.

Drive composer software export:

1. Connect the computer and the inverter via USB, and configure the COM port to establish communication.
2. Entry version: Export records directly in the event log module.
3. Professional version: Can export pre- and post-fault sampling data and complete record files from Fault data logger.

2.How to set parameters to reduce the overvoltage/overload failure rate of ACS880-01-206A-3 when the lifting machinery frequently starts and stops?

1. Optimize the start and stop parameters: extend 22.12 (acceleration time) and 22.13 (deceleration time) to 10-20 seconds; set 22.02 to heavy load mode to improve short-term load tolerance.
2. Suppress braking overvoltage: 30.33 is set to manual overvoltage mode, and the 380V power grid threshold is set to 720V; when an external braking resistor is connected, the braking power parameters are matched to speed up regenerative power consumption.
3. Adjust the protection parameters: 31.25 (overload protection coefficient) is set to 150%-160%; 31.26 (thermal time constant) is set to 20-30 minutes according to the motor rotor material; 20.12 (current limit value) is set to 1.2 times the overload coefficient.
4. Auxiliary optimization: Turn on fault self-recovery (set 3 retries, 5-second interval); add 2%-5% low-frequency voltage compensation to avoid stalling due to insufficient torque.
