This object helps to determine the rotor angle computed using resolver feedback.
SubIndex description:
- 0x01 (Resolver angle): It returns the resolver's electrical angle directly
- 0x02 (Resolver tolerance): This object indicates the level or sensitivity to parity errors when receiving resolver's information. Lower values indicate high sensitivity to errors, meaning a fault will be triggered with a lower amount of errors detected.
- 0x03 (Resolver pole pairs): This object indicates the level of pole pairs of the resolver. It is used to compensate the output angle in relation to the motor's electrical angle.
0x04 (Resolver polarity): This object allows swapping the polarity of the output angle, to avoid having to physically re-install the resolver.
Polarity Description 0 Normal polarity 1 Reversed polarity - 0x05 (Resolver adapted angle): It returns the resolver angle after applying a conversion factor (based on the motor and resolver pole pairs). The result is an angle that can be related directly to the electrical cycle of the motor.
0x06 (Resolver error code): It returns the code of the last error detected.
Error code Error type 0 No error 1 Loss of Signal 2 Loss of Track 3 Degradation of Signal 4 SPI parity error 0x07 (Resolver error filter):This object indicates the level or sensitivity to resolver error bits. Lower values indicate high sensitivity to errors, meaning a fault will be triggered with a lower amount of errors detected.
