“ATV212 energy consumption ” Industry BU Drives Domain Test in lab report DRIVES-FT-CC-004 / Rev 1
Introduction The aim of this document is to provide some explanation for the unit of some parameters concerning the Power & Energy consumption on ATV212. I will explain specially the unit of : FE29: ATV212 input power, FE30: ATV212 output power, FE76: ATV212 integral input power , FE77: ATV212 integral output power,
FE29 : The ATV212 input power FE29 This parameters provide the instantaneous ATV212 input power, the unit of this parameter is always 0.01kw (doesn’t depend to any other parameter or drive sizing). Example: • If FE29= 169, this means that the instantaneous ATV212 input power is 1,69 kw. • If FE29= 1256, this means that the instantaneous ATV212 input power is 12,56 kw.
FE30 : The ATV212 output power FE30 This parameters provide the instantaneous ATV212 output power, the unit of this parameter is always 0.01kw (doesn’t depend to any other parameter or drive sizing). Example: • If FE30= 155, this means that the instantaneous ATV212 output power is 1,55 kw. • If FE30= 1758, this means that the instantaneous ATV212 output power is 17,58 kw.
F749: Power Consumption unit (define the unit for FE76 & FE77) The parameter F749 provide the unit For and only for the both parameter FE76 & FE77. The factory setting of F749 depends on the drive rating. The values of factory setting is giving in this table.
F749: Power Consumption unit The parameter definition F749 giving on the manual is wrong. Below the good list :
FE76 : The ATV212 integral input power ∫ FE76 This parameters provide the integral of ATV212 input power, the unit of this parameter depend to the parameter F749 ( be careful because the factory setting of F749 depend the drive size, see table in page 4) . Example ( F749=0 , so the unit will be 1kw): • If FE30= 12, this means that the integral ATV212 input power is 12 kw. • If FE30= 175, this means that the instantaneous ATV212 input power is 175 kw. Example ( F749=1, so the unit will be 10kw): • If FE30= 1, this means that the integral ATV212 input power is 10 kw. • If FE30= 17, this means that the integral ATV212 input power is 170 kw.
FE77 : The ATV212 integral output power ∫ FE77 This parameters provide the integral of ATV212 output power, the unit of this parameter depend to the parameter F749 ( be careful because the factory setting of F749 depend the drive size, see table in page 4) . Example ( F749=0 , so the unit will be 1kw): • If FE30= 23, this means that the integral ATV212 output power is 23 kw. • If FE30= 245, this means that the instantaneous ATV212 output power is 245 kw. Example ( F749=1, so the unit will be 10kw): • If FE30= 3, this means that the integral ATV212 output power is 30 kw. • If FE30= 96, this means that the integral ATV212 output power is 960 kw.
FD76 & FD77 : The ATV212 integral input power ∫ FE76 This parameters provide the integral of ATV212 input power in 32bits with FD76 as High word and FD77 is the low word, the unit of this parameter is always 0.01kw (doesn’t depend to any other parameter or drive sizing). Example: • If FD76= 0 and FD77= 3000, this means that the integral ATV212 input power is 30,00 kw. ( [0x 65535 ]+ 3000 = 3000 “unit is 0.01kw”). • If FD76=2 and FD77= 1256, this means that that the integral ATV212 input power is 1323,26 kw • ( [2x 65535] + 1256 = 132326 “unit is 0.01kw”).
FD78 & FD79 : The ATV212 integral output power ∫ FE77 This parameters provide the integral of ATV212 output power, the unit of this parameter is always 0.01kw (doesn’t depend to any other parameter or drive sizing). Example: • If FE30= 155, this means that the instantaneous ATV212 output power is 1,55 kw. • If FE30= 1758, this means that the instantaneous ATV212 output power is 17,58 kw.
Test with 4kw drive I use a test bench with motor 1.5kw loaded. I run a drive around 9~10 hours and I check consumption registers. As the factory setting of F749 for an ATV212 4kw is 1. this mean that the unit of FE76 and FE77 is 10kw, so the value read on these register should be multiply by 10kw. on our case the ATV212 integral input power 10kw ( as FE76=1). By using FD76/FD77, you can get the input power integral (32bit) with unit 0.01kw, so integral input power is 14,15kw value got as = [(FD76 x 65535 )+(FD77)] with unit 0.01kw.
Test with 4kw drive I change then F749 from 1 to 0, this means that the new unit of FE76 (input power) & FE77 (output power) will be in 1kw. As I check the consumption registers, on the test above, the ATV212 integral input power 14kw ( as FE76=14) and the ATV212 integral output power 12kw ( as FE77=12). By using FD76/FD77, you can get the input power integral (32bit) with unit 0.01kw, so integral input power is 14,18kw , value got with this formula = [(FD76 x 65535 )+(FD77)] with unit 0.01kw. By using FD78/FD79, you can get the output power integral (32bit) with unit 0.01kw, so integral output power is 12,29kw , value got with this formula = [(FD78 x 65535 )+(FD79)] with unit 0.01kw.
Conclusion The unit of • FE29 “ATV212 input power “ is : 0.01kw. • FE30 “ATV212 output power” is : 0.01kw. • FE76: ATV212 integral input power depend on F749 value (The factory setting of F749 depends on the drive rating) • FE77: ATV212 integral output power depend on F749 value (The factory setting of F749 depends on the drive rating) • FD76 & FD77 ATV212 integral input power unit is 0.01kw ( it’s same as FE76 but it’s value is in 32 bits, FD76 is High word and FD77 is low word). • FD78 & FD79 ATV212 integral output power unit is 0.01kw ( it’s same as FE77 but it’s value is in 32 bits, FD78 is High word and FD79 is low word).
