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 MintDrive
II
. This provides the
MintDrive
II
with an equivalent resolution of 4096 pulses per revolution (ppr), although this can
be reconfigured in the WorkBench v5 Commissioning Wizard to provide 1024 ppr. The
MintDrive
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).
