In the user guide, it states the motor rated current is used to determine the limit of the current out of the speed controller. Is this correct? If I want to run my system at 3x rated, then I have to set my rated motor current to 300% of rated?
Thanks for the help,
KMS defines the maximum commandable current to be the rated current of the motor. The current reference comes from the speed controller and so its output limit will be the maximum commandable current in the system.
You can change the maximum and minimum values for the speed controller output limit programatically by modifying the variables:
user.command.IqRefMax & user.command.IqRefMin
These are Q24 variables that are normalized against FULL_SCALE_CURRENT. So ensure that your FULL_SCALE_CURRENT value is large enough to support your higher current.
Thanks Adam, That is what I needed to know.
