10.4 Resolver Option MCB 103MCB 103 Resolver option is used for interfacing resolver motor feedbackto VLT AutomationDrive. Resolvers are used basically as motor feedbackdevice 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 coverSelection of parameters: 17-5x resolver Interface.MCB 103 Resolver Option supports a various number of resolver types.Resolver specifications:Resolver Poles par. 17-50Poles: 2 *2Resolver Input Volt-agepar. 17-51Input Voltage: 2.0 – 8.0 Vrms*7.0VrmsResolver Input Fre-quencypar. 17-52Input Frequency: 2 – 15 kHz*10.0 kHzTransformation ratio par. 17-53Transformation Ratio: 0.1 – 1.1*0.5Secondary input volt-ageMax 4 VrmsSecondary load App. 10 kΩNB!The Resolver Option MCB 103 can only be used withrotor-supplied resolver types. Stator-supplied resolv-ers cannot be used.LED indicatorsLED 1 is on when the reference signal is OK to resolverLED 2 is on when Cosinus signal is OK from resolverLED 3 is on when Sinus signal is OK from resolverThe LEDs are active when par. 17-61Feedback Signal Monitoring is settoWarning orTrip.FC 300 Design Guide 10 Options and AccessoriesMG.33.BC.02 - VLT® is a registered Danfoss trademark 21310
