– [10] Motion-based
The motion-based PolID technique is the preferred technique if the motor can move.
The motor traverses left and right along a defined path. If both paths are identical, the
pole position identification (PolID) was successful.

2. Select the "Pole position identification" option to activate the technique.
Why was synchronization
successful?
● The motor provides insufficient or no torque.
● The motor becomes hot too fast.
The pole position identification (PolID) technique provides coarse synchronization. If zero
marks are present, after traversing the zero mark(s), the pole position is calibrated
automatically with the zero mark position (fine synchronization). The zero mark position must
be calibrated mechanically or electrically (p0431). If the encoder system permits this
calibration, a fine synchronization is recommended (p0404.15 = 1) because it avoids
measurement spreads and permits an additional test of the determined pole position.
Suitable zero marks are:
● A zero mark in the complete traversing range
● Equidistant zero marks
● Distance-coded zero marks

In the "Mechanical system" screen form, check the settings of the position control and adjust
them if necessary. Depending on the encoder type selected for position control and the
motor encoder, various configurations are displayed for the mechanical system.
The "Position tracking" option allows the load position to be reproduced when using
gearboxes. This option can also be used to extend the position range. The position tracking
of the load gear however, is only relevant for a motor encoder (encoder 1).
