FAQ:
1. What are the current threshold and temperature limits for triggering the 200% overload (90A) 2 second capability of the ACS880-01-045A-3?
- Current threshold: The rated output current is 45A, and 90A corresponding to 200% overload is the core current trigger threshold. However, this overload trigger is also related to the parameter setting. It is necessary to ensure that 31.25 (overload protection coefficient) in parameter group 31 is set to a level suitable for 200%. At the same time, the current limit value (parameter 20.12) is recommended to be set to 1.2 times the overload coefficient as a buffer to avoid false triggering or protection failure. And this overload is only a short-term tolerance state, and the duration is strictly limited to 2 seconds. Exceeding the time will trigger the F0011 overload fault.
- Temperature limits: Overload capability is based on normal heat dissipation and ambient temperature conditions. The ambient temperature for this model is generally adapted to 40°C. At this temperature, it can stably support the performance of 200% overload for 2 seconds; if the ambient temperature exceeds 40°C, or the inverter radiator has poor heat dissipation due to dust accumulation, fan failure, etc., the DEV OVERTEMP (drive radiator overheating) fault will be triggered in advance. At this time, the 200% overload 90A 2-second capability will not be triggered normally, and may even be triggered before 2 It will trip due to abnormal temperature within seconds.
2.Compared with the standard IP21 version, what are the changes in the hardware structure of the IP55 protection version of ACS880-01-045A-3?
- Reinforced shell sealing: It adopts a fully enclosed structure + seam sealing ring, and multi-point bolt fastening replaces buckles to improve dustproof and water-proof capabilities.
- Cooling system modification: Either install an external radiator, or replace with a high-pressure sealed fan + optimize the air duct to balance the heat dissipation needs of a closed environment.
- Wiring port sealing upgrade: All ports are equipped with sealed glands/waterproof junction boxes, and the control interface uses locked waterproof connectors.
- Adjustment of the installation structure: A special bracket is installed to raise the fuselage, the open ventilation grille is cancelled, and the volume and weight are slightly increased.
3.What is the grade of the built-in EMC filter of ACS880-01-045A-3? Does it meet the standards for use in machine tool shops with high electromagnetic interference?
ACS880-01-045A-3 has a built-in Class C2 EMC filter, complies with EN61800-3 standards, is suitable for industrial environments, and can meet the use needs of machine tool workshops with high electromagnetic interference.
In extremely dense high-power equipment scenarios, it is recommended to install incoming line reactors or Class C3 filters and standardize cable routing.
