Frequently Asked Questions (FAQ) - stm32mcu
This is a tool that automatically measure the electrical parameters of PMSM motors. The specification of an electric motor may not be known and is determined in less than a minute.
Typically, this fault message appears because there is insufficient current provided to support the required speed acceleration.
1、 Decrease the speed acceleration rate :
Increase the “Speed ramp duration” parameter;
Set the “Speed ramp final value” parameter to 30% of your maximum application speed.
2、Increase the start-up current :
Increase the “Current ramp initial value” parameter;
Increase the “Current ramp final value” parameter up to the “Nominal Current” parameter of the motor;
Check the “Include alignment before ramp-up” box to make the start-up phase more deterministic, and follow the FAQ on "Basic parameters settings for the ramp-up"
