Resolver Option MCB 103

"
MCB 103 Resolver option is used for interfacing
resolver motor feedback to the FC 300
AutomationDrive. Resolvers are used basically as
motor feedback devices for permanent magnet
brushless synchronous motors. When the resolver
option is ordered separately, the kit includes:
