5.4 Motor Configuration
There are a number of parameters that are required when configuring a specific motor for a drive. For standard
motors, these parameters will be held in a database on the PC, and downloaded by the GUI. For non-standard
motors, the user must enter these parameters.
In addition to the typical electrical motor parameters which are downloaded (e.g. Number of Motor Poles,
Resistance, Inductance, etc...), tuning parameters for the current loop, position feedback, commutation, motor
thermal characteristics etc, need to be set for the drive, as these parameters will differ for each motor. The
following section lists and explains the meaning of each parameter. More detailed descriptions of these
parameters are given in the appropriate parts of this section of the manual.
The parameters are grouped as listed below.

5.4.3 Current Loop Parameters
Because of the different electrical characteristics of each motor, the current loop must be optimised for the motor
to be used with the controller. The control loop structure is described elsewhere, the parameters that must be set
are summarised below: -
