3.18 Commissioning SIMOTICS T-1FW6 built-in torque motors
Evaluation of the results (applies to both measuring techniques)
For a positive drive direction (definition, refer to the "Determining the positive direction of the
drive (Page 251)" figure, the sawtooth must increase monotonously between 0° and 360°,
refer to the "Ideal characteristic of the EMF voltages and the pole position angle for an
optimally commutated drive (Page 265)" figure.
If the curve is decreasing monotonously, and the phase sequence is EMF phase U - EMF
phase V - EMF phase W, then you must change the control sense of the drive if necessary
via p0410 bit 0 "Invert actual speed value". If the position controller is being used, then you
must also check p0410 bit 1 "Invert actual position value". See the "Screen form for entering
additional encoder data (Page 250)" figure in Chapter "Parameterizing a motor and
encoder".
