3.7.1 Resolver option - X8
The resolver connections are made using the 9-pin D-type male connector X8. Twisted pair
cables must be used for the complementary signal pairs e.g. SIN+ and SIN-. The overall cable
shield (screen) must be connected to the metallic shell of the D-type connector.

Description Resolver input with 14-bit resolution
The resolver input is used to create an encoder signal inside the FlexDrive
II
. This provides the
FlexDrive
II
with an equivalent resolution of 4096 pulses per revolution (ppr), although this can
be reconfigured in the W orkBench v5 Commissioning Wizard to provide 1024 ppr. The
FlexDrive
II
provides an input accuracy of ±3 counts. When used with a typical Baldor BSM
series resolver motor the combined accuracy is ±11 counts (calculated with the input
equivalent resolution set to the factory preset value of 4096 ppr).
