Resolver Input MCB 103
MCB 103 Resolver option is used for interfacing resolver
motor feedback to VLT
®
AutomationDrive FC 302. Resolvers
are used as motor feedback devices for permanent magnet
brushless synchronous motors.
When the resolver option is ordered separately, the kit
includes:
•
Resolver input option.MCB 103.
•
Enlarged LCP fixture and enlarged terminal cover.
Selection of parameters:
17-5* Resolver Interface
.
MCB 103 Resolver Option supports a various number of
rotor resolver types.

NOTICE
The MCB 103 can be used with only rotor-supplied
resolver types. Stator-supplied resolvers cannot be used.
LED indicators
The LEDs are active when
parameter 17-61 Feedback Signal
Monitoring
is set to
[1] Warning
or
[2] Trip
.
LED 1 is on when the reference signal is OK to resolver.
LED 2 is on when Cosinus signal is OK from resolver.
LED 3 is on when Sinus signal is OK from resolver.
