9.4 Resolver Option MCB 103
MCB 103 Resolver option is used for interfacing resolver
motor feedback to VLT
®
AutomationDrive. Resolvers are
used 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:
17-5* Resolver Interface
.
MCB 103 Resolver Option supports a various number of
rotor resolver types.

NOTICE!
The Resolver Option MCB 103 can be used with only
rotor-supplied resolver types. Stator-supplied resolvers
cannot be used.
LED Indicators
The LEDs are active when
17-61 Feedback Signal Monitoring
is set to
Warning
or
Trip
.
LED 1 is on when the reference signal is OK to resolver
LED 2 is on when cosine signal is OK from resolver
LED 3 is on when sinus signal is OK from resolver
