Program features 937. Switch on the power to the drive/inverter unit.8. Enter the number of inverter modules present into parameter 95.13 Reduced runmode.9. Reset all faults and start the drive/inverter unit. The maximum current is nowautomatically limited according to the new inverter configuration. A mismatchbetween the number of detected modules (95.14) and the value set in 95.13 willgenerate a fault.After all modules have been reinstalled, parameter 95.13 Reduced run mode must bereset to 0 to disable the reduced run function. In case the inverter is equipped with acharging circuit, the charging monitoring must be reactivated for all modules. If theSafe torque off (STO) function is in use, an acceptance test must be performed (seethe hardware manual of the drive/inverter unit for instructions).SettingsParameters 06.17 (page 131) and 95.13…95.14 (page 408). du/dt filter supportWith an external du/dt filter connected to the output of the drive, bit 13 of 95.20 HWoptions word 1 must be switched on. The setting limits the output switchingfrequency. With frame size R5i…R7i inverter modules, the setting also forces thedrive/inverter module fan to full speed. Note that the setting is not to be activated withinverter modules with internal du/dt filters.SettingsParameter 95.20 HW options word 1 (page 411). Sine filter supportThe control program has a setting that enables the use of sine filters (availableseparately from ABB and others).With an ABB sine filter connected to the output of the drive, bit 1 of 95.15 Special HWsettings must be switched on. The setting limits the switching and output frequenciesto• prevent the drive from operating at filter resonance frequencies, and• protect the filter from overheating.With a custom sine filter, bit 3 of 95.15 Special HW settings must be switched on.(The setting does not limit the output frequency.) Additional parameters must be setaccording to the properties of the filter as listed below.ghv Vertriebs-GmbH | Am Schammacher Feld 47 | 85567 Grafing | Telefon + 49 80 92 81 89 0 | info@ghv.de | www.ghv.de
