Current fluctuation issue with the Mapo controller of the Pinuo PMAC801D1 model
Thread Content
I have a question: The current fluctuation in the MPact controller of the Pinuo PMAC801D1 model is extremely large. Even when the motor is not running, there are currents in the range of several thousand amps. During operation of the motor, these current fluctuations often cause the system to shut down. How can this problem be solved?
Can there still be a current of several thousand amps even when the motor isn’t running? That’s absolutely exaggerated. How is the current measured, and is the unit indeed amps?
First, check whether the protection is functioning properly; second, examine the current transformer. In a situation like yours, it’s more likely that there is an issue with the protection.
Based on your description, the microcomputer-based integrated protector is damaged; it has nothing to do with the manufacturer or brand. If you write this to indicate that you are looking for a microcomputer-based integrated protection device, will the other party agree?
