Danfoss VLT micro drive FC 51 Name Plate

Image
In this Article, we are going to discuss about what specifications are mentioned on the Danfoss VLT micro drive FC 51 name plate sticker. Welcome to controls and systems blog page, The nameplate sticker is located on the top of each VFD drives and shows the ratings, serial number, warnings catalog number, and other relevant data for each unit. This nameplate sticker is mostly the same in the VLT model VFD drives, with only a few changes in the some VLT model VFD drives. 1 st ROW: ( TYPE CODE ) Position 1 - 3 [FC]-  is Product group, Possible choice is: Frequency converters, Position 4 - 6 [051]  is Series and product type, Possible choice is: Micro Drive, Position 7 - 10  [P]  is Power size, Possible choice is: 0.18 to 22 kilo watt. Position 11 - 12  [S2]  is Mains voltage, Possible choice is: S2 that means Single phase 200 to 240 Volt AC, T2 that means 3-phase, 200 to 240 Volt AC, T4 that means 3-phase, 380 to 480 Volt AC, ...

SIEMENS V20 VFD DRIVE FAULTS CODE LIST PART-1

Image
In this article  we are going to discuss about siemens v20 vfd drive fault Cause and Remedy for this  fault codes ( F1, F2 , F3 , F4 , F5 , F6 , F11 , F12 , F20 , F35 )   SIEMENS V20 DRIVE F1  -  FAULT:    Overcurrent CAUSE : Motor power (P0307) does not correspond to the inverter power (r0206). Motor lead short circuit Earth faults r0949 = 0: Hardware reported r0949 = 1: Software reported r0949 = 22: Hardware reported REMEDY : Check the following: Motor power (P0307) must correspond to inverter power (r0206). Cable length limits must not be exceeded. Motor cable and motor must have no short-circuits or earth faults. Motor parameters must match the motor in use. Value of stator resistance (P0350) must be  correct. Motor must not be obstructed or overloaded. Increase ramp-up time (P1120) Reduce starting boost level (P1312) F2  -  FAULT:  Overvoltage CAUSE : Main supply voltage too high Motor is in regenerative mode r0949 = 0: Hardw...

SIEMENS VFD FAULTS CODE LIST PART-2

Image
In this article  we are going to discuss about siemens v20 vfd drive fault Cause and Remedy for this fault codes ( F41, F51 , F52 , F60 , F61 , F62 , F63 , F64 , F71 , F72 ) Fault Vfd Drive F41   -  FAULT: Motor data identification  failure Motor CAUSE : Motor data identification failed. r0949 = 0: No load applied r0949 = 1: Current limit level reached during identification. r0949 = 2: Identified stator resistance less than 0.1% or greater than 100%. r0949 = 30: Current controller at voltage limit r0949 = 40: Inconsistency of identified dataset, at least one identification failed Percentage values based on the impedance Zb = Vmot,nom / sqrt(3) /  Imot,nom REMEDY : Check the following: r0949 = 0: is the motor connected to the inverter? r0949 = 1 - 49: are the motor data in P0304 - P0311 correct? Check what type of motor wiring is required (star, delta). F51 -  FAULT:   Parameter EEPROM fault EEPROM CAUSE : Read or write failure while acce...
