VLT ® 2000 Series Description of parameters Warning parameter messages [15]: Frequency low re parameter 210 value: 32768 Frequency high re parameter 211 value: 16384 Current limit, re power section value: 8192 Key blocked value: 2048 Motor overload value: 1024 Inverter overload value: 512 Outside frequency range value: 256 Current higher than para. 213 value: 128 Data locked value: 64 Read only value: 32 Current limit re control card value: 16 Overvoltage value: 8 Undervoltage value: 4 Can only be changed in stop mode value: 2 Parameter limit value: 1 In case of Short circuit, Earth connection and Excess temperature, re power section, Trip locked will also occur.
This will give a typical reading: Earth connection 4096 + Unspecified inverter fault 256 + Trip locked 1 Reading in para. 502, index 18: 4353 I 503 Coasting (COAST) Value: Digital (DIGITAL) [0] Bus (BUS) [1] Logical and (AND) [2] ✭ Logical or (OR) [3] Usually only one warning occurs at a time, so one of the figures in parameter 502, index 15, will show. In the event of several simultaneous warnings, e.g. Motor overload and Current limit, re contral card, the two values are added: Description: See parameter 510 I 504 Q stop (Q-STOP) Value: Digital (DIGITAL) [0] Bus (BUS) [1] Logical and (AND) [2] ✭ Logical or (OR) [3] Inverter overload 512 + Current limit re control card 16 Reading in para.
502, index 15: 528 Alarm parameter messages [18]: Excess temperature, re power section value: 16384 Earth connection value: 4096 Overvoltage value: 1024 Undervoltage value: 512 Unspecified inverter fault value: 256 Inverter overload value: 128 Motor overload value: 64 Short circuit value: 16 VLT attemps restart value: 8 Overcurrent value: 4 Trip locked value: 1 Description: See parameter 510. In contrast to warnings, alarms will always be com- bined, i.e. at least 2 of the alarm parameters apply, e.g. Unspecified inverter fault will usually occur with another alarm, e.g. Inverter overload. It will give the following reading:
Unspecified inverter fault 256 + Inverter overload 128 Reading in para. 502, index 18: 384 78 MG.20.B6.02 – VLT is a registered Danfoss trademark
