An operational encoder connection is an essential condition of the commissioning of the velocity and
position controller. If the encoder is not connected or not connected correctly, the motor would make
uncontrolled movements.
The test of the encoder connection is carried out internally in the drive module. At first, it is tested, if a
certain number of impulses (e.g. 100) is exceeded at standstill (about 1 sec.). This could be caused
by an open connection or faults. Afterwards, the motor is moved in one direction, until a preset
number of impulses (1,000 Inc.) is achieved or until a preset time (100 ms) has been exceeded. A
pause of about 2 seconds is to make sure that the motor is once again brought to a standstill.
Afterwards, the same procedure is made for the other direction.
