DescriptionSets the drive/motor to operate in voltage test mode. In this mode a voltage command can be set using a test reference consisting of a limited ramp.  For AC motors (like for example the brushless motors), the test mode offers also the possibility to rotate a voltage reference vector with a programmable speed. As 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 voltage test mode has been foreseen to facilitate the testing during the setup phase. It is not intended for normal operation

 

The new motion mode becomes effective at the next update command UPD.

 

Example

MODE VT;                //Voltage Test Mode

REFTST_V = 5022;        //Reference saturation value = 1[V]

RINCTST_V = 4;        //Reference increment value = 1[V/s]

UPD;                        //Update immediate
