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).
