Siemens SINAMICS S120 Commissioning Manual page 225

• Resolver with integer ratio from the number of motor pole pairs to the number of encoder
pole pairs
• Incremental encoder with an integer ratio from the number of motor pole pairs to the
number of encoder pulses
Note
Using the Function Manual
Please also refer to the description of the pole position identification provided in the "SINAMICS
S120 Function Manual Drive Functions". The supplementary conditions for using the individual
techniques are also described in the appropriate chapter.
Determining the suitable technique for the pole position identification
Danger to life caused by the movement of the motor when measuring unbraked motors
When carrying out the measurement for motors that are not braked, the current that flows can
cause the motor to move, which in turn can lead to death or severe injuries.
• Ensure that nobody is present in the hazardous zone and that the mechanical system can
Brake available
Motor can move freely
Motor has no iron
Parameterizing the pole position identification
The pole position identification (PolID) differs depending on the motor type:
• For Siemens motors
• For motors that are not listed in the motor selection.
Requirements
• You have completely specified and configured the motor used in the device configuration of
the drive axis.
Note
This basic parameterization cannot be performed without having completed this full
configuration.
Procedure for Siemens motors
When using standard Siemens motors use the automatic default setting for the PolID.
