Tips: Can a 50Hz motor run on 60Hz power source?

The frequency is increased from 50 Hz to 60 Hz and the motor will not work properly. The main effects to the motor are:
First, the current and output torque are reduced. The motor is an inductive load, the frequency increases, the impedance of the motor increases, and the current decreases. The output torque is also reduced.
Second, the speed increases. The synchronous speed of the motor is proportional to the frequency of the power supply. Taking a two-pole motor as an example, the synchronous speed is 3000 rpm at 50Hz and the synchronous speed is 3600 rpm at 60Hz.
Third, the iron loss increases. The iron loss is mainly eddy current. The eddy current is proportional to the frequency, and the eddy current increases to increase the temperature rise of the motor.

I need your support
Hello, I need your support. I'm using your product HZ-50-3345. It's Hz is fixed at 40Hz, and I need to change it to 0Hz, but I don't know how. Please let me know how to change it.

Unfortunately, the minimum frequency supported by our converter is 40Hz, and it can Not output 0Hz.
I have a technical question regarding the Frequency Converter
I have a technical question regarding the 400Hz Frequency Converter. For longevity purposes, should the unit be turned off when not in use or left on?
From: Blake | Date: 05/02/2024

In order to extend the service life, the Converte should be shut down when Not in use and should be cleaned and maintained regularly. You can refer to the user manual instructions in the attachment.
Why is this frustrating stuff happening?
We have successfully installed you 45kva unit we purchased in a climate controlled room.  The unit operates and powers all of the house’s load, but randomly (sometimes at night, sometimes in the day) trips off and requires us to reset the panel on the front.
Why is this frustrating stuff happening?

This situation should be caused by fluctuations in the electrical load of the entire room, resulting in overload. Please stop running the converter now.
You can refer to the attached document to rotate the potentiometer counterclockwise for 8 turns, appropriately increase the current protection threshold, and test again.
If you still have problems, please send us a picture of the converter's nameplate label for further confirmation. And list the power, voltage, current and other information of all loads in the entire room.
