" Resolver Option MCB 103
MCB 103 Resolver option is used for interfacing
resolver motor feedback to the FC 300
AutomationDrive. Resolvers are used bas ically as
motor feedback devices for permanent magnet
brushless synchronous motors. When the resolver
option is ordered separately, the kit includes:
• Resolver option MCB 103
• Enlarged LCP fixture and enlarged terminal cover
Selection of parameters: 17-5x resolver interface.
The resolver interface must support one resolver
with the following specifications:
