Frequently Asked Questions
Can this inverter work with motors from brands other than Lenze?
Yes, it can. However, you need to correctly configure key parameters like motor power, rated current, and speed. It's recommended to check the motor datasheet first to ensure parameter matching.
Does it support the communication protocols commonly used in European factories?
Definitely. It's compatible with EtherCAT, PROFINET, PROFIBUS and other mainstream protocols in Europe, which can directly connect to most factory control systems.
What should I do if the inverter shows an overload fault during operation?
First, check if the load is too heavy (exceeding 150% for 60s or 200% for 3s). If the load is normal, check the motor wiring for poor contact, or adjust the overload protection parameters appropriately according to the actual working conditions.
Is the STO safety function mandatory for use in the EU?
Not mandatory for all scenarios, but it's required in applications involving personnel safety (such as hoisting, automated assembly lines). It's recommended to confirm local safety standards before installation.
Can the inverter be used in high-temperature environments (e.g., 60℃ workshops)?
No, its maximum operating temperature is 55℃. When the temperature exceeds 45℃, you need to derate by 2.5% for each 1K increase. For 60℃ environments, additional cooling measures (like fans or heat sinks) are necessary.
How to solve the problem of inaccurate positioning in servo mode?
First, check if the encoder is properly installed and connected. Then, verify the position measurement parameters (such as encoder resolution) in the inverter. If there's still an issue, calibrate the servo system again.
Does the inverter come with a power cord, or do I need to buy it separately?
It doesn't come with a power cord. You need to purchase it separately according to the local voltage standard (e.g., 400V 3-phase in EU, 480V in US) and the inverter's power rating.
Can it be used for outdoor applications?
No, its protection class is IP20, which is only suitable for indoor use. If used outdoors, you need to install it in a sealed cabinet to prevent dust, rain and other external factors from affecting it.
What's the difference between this inverter and a dedicated servo drive?
It has servo-level positioning accuracy and dynamic response, but the cost is lower than a dedicated servo drive. The main difference is that it's more versatile (compatible with both synchronous and asynchronous motors) but not suitable for ultra-high-precision scenarios (e.g., micron-level positioning).
