Type:
Single Turn - Brushless
Resolution (all):
12 Bits (4096 increments)
Linearity (standard):
+/-20 arc minutes (resolver only)
(+/-30 arc minutes combined with
R/D converter in controller)
Linearity (specials):
+/-3 to +/-10 arc minutes
(resolver only)
(+/-7 to +/-14 arc minutes
combined with R/D converter
in controller)
Note:
A resolver's linearity errors are repeatable at all
positions of its 360 degree rotation. Therefore, once
appropriate setpoints are established, machine performance
is consistent every cycle.
