InstaSPIN-FOC requires a few parameters from the motor to run with best performance. The majority of the time this is only done once, and requires the motor to be removed from any mechanical load so it is able to spin freely. A few steps during the identification process require motor rotation in open loop. That is the reason why we require no mechanical load in the motor since it is easy to stall a motor when running in open loop control. When motor can be removed from mechanical load, there is no issue with InstaSPIN-FOC's identification process, and at the end, motor parameters are available in a watch window for future use.
On the other hand, some applications are, by definition, attached to a mechanical load. Examples of these applications are compressors, some direct drive washing machines, and geared motors with sealed enclosures. For those applications, the user requires to run motor identification differently in order to extract motor parameters with no or minimum motor rotation.
