The torque and voltage test modes have been designed to facilitate the testing during the setup phase. In these test modes, either a voltage or a torque (current) command can be set using a test reference consisting of a limited ramp (see figure below).
Reference profile in test modes
For AC motors (like for example the brushless motors), the test mode offers also the possibility to rotate a voltage or current reference vector with a programmable speed. As a result, these motors can be moved in an “open-loop” mode without using the position sensor. The main advantage of this test mode is the possibility to conduct in a safe way a series of tests, which can offer important information about the motor parameters, drive status and the integrity of the its connections.

Remark: The Motion test is a special test mode to be used only in some special cases for drives setup. The Motion Test mode is not supposed to be used during normal operation
