Tracking error means the difference between the setpoint and measured actual output value. For example in a linear axis tracking error can be the distance between setpoint position and the position where axis really lies at the given moment.
In modern motor drives it's possible to define the tolerance value of tracking error which is allowed before drive enters in a fault state. Tracking fault is useful for protecting the machine or users from damage if something is preventing mechanism from moving. In Granity this value is entered in FPT and FVT parameters.
