Preface

1.5.2  Abnormal operation

When exceeding the permissible limit values for voltage, current or temperature the current 

flow between DC link and mains is blocked during regeneration. An appropriate error mes

-

sage is also displayed during supply. The unit must be disconnected from the supply system 

or the load must be switched off in case of overcurrent or overload. This can be done by 

opening the control release of the frequency inverter.
At factory setting the modulation is switched off in case of a net phase failure and error mes-

sage E.nEt is displayed.
Special adjustments from KEB are necessary if the modulation and/or the standard operation 

should start again within a defined time in case of return of power supply.

Product description

This instruction manual describes the power supply and regenerative unit KEB COMBIVERT 

R6-N. The COMBIVERT R6-N has the following features.

The supply unit
•  converts a three-phase input voltage into DC voltage. 
•  supplies single KEB frequency inverter or via DC interconnection.
•  can be parallel connected while maintaining a base load if higher power supply is required.
•  increases the stability of the DC link voltage in the DC interconnection.

The regenerative unit
•  feeds back the excess energy from generatoric operation into the supply system.
•  reduces the energy demand.
•  reduces the heat emission.
•  is environmentally friendly and space-saving.
•  replaces braking resistor and braking transistor.
•  is cost-saving.

• 

has the same current flow (harmonic components) such as feed-in and rarely noise 

level

The COMBIVERT R6-N is generally protected against overcurrent, ground fault and tempera-

ture. Appropriate dimensioned DC fuses protects the DC link circuit against short-circuit. The 

following accessories are necessary for operation with the COMBIVERT R6-N:
•  Mains choke
• 

EMC filter E6 (for observance of EMC standard) respectively voltage limitation
