Argon resolver adapter
Argon resolver adapter is a small sized device that adds resolver feedback device support to Argon servo drive.
Obtaining adapter
Adapter is available from Granite Devices web shop:
Adapter may be also self-built (schematics: Media:argonresolveradapter_schematics.png)
Usage
Wiring
Resolver has total of 6 wires and 3 windings: one for rotor (primary) and two stators (secondaries). Rotor connects to the adapter pins A+ and A- while secondaries connect to B+/- and C+/-.
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.
A shielded cable is required and shield should be connected to D-sub connector frame to reduce EMI noise. 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.
Configuration
To configure drive for resolver:
- Ensure that drive has at least firmware package version 1.3.0
- Choose Resolver from feedback device parameter FBD
- Set feedback device resolution FBR to 2048 PPR (resolver will give same resolution as 2048 PPR / 8192 count encoder)
- Tune motor normally. If motor is always unstable or locks motor position, try changing direction of feedback by toggling checkbox FBI
