If pin-out of resolver is unknown, it can be found out with multimeter by finding the wire pairs where coils are connected. Rotor can be identified by searching for lowest resistance coil. Stators typically have at least twice as high resistance compared to rotor. | If pin-out of resolver is unknown, it can be found out with multimeter by finding the wire pairs where coils are connected.

Shielded cable for motor power leads and connection of cable shield and motor frame to drive PE is strongly recommended if not necessary to reduce noise. After all noise countermeasures, some noise is still expected from resolver read-out due to analog nature of the signals. This noise will appear as position value noise and motor hiss when standing still or rotating slowly. |
Finally plug the adapter to Argon J1 port. | Finally plug the adapter to Argon J1 port. | ||

Example: if you find position counter changes 16760 counts per mechanical revolution, then divide it by 4 to get 4190, then round it to 4096 which is the correct value for FBR. | Example: if you find position counter changes 16760 counts per mechanical revolution, then divide it by 4 to get 4190, then round it to 4096 which is the correct value for FBR. | ||
