For applications that require cyclic switching on and off of the drive converter, maintain an off-time of at least 5 min after the last switch on. If you require shorter cycle times please contact KEB Automation KG. Short-circuit proof The drive converters are conditional short-circuit proof. After resetting the internal pro- tection devices, the function as directed is guaranteed.
Drive converters with safety function are limited to a service life of 20 years. Thereafter the devices must be replaced. Drive converters of the KEB Automation KG are professional, electronic devices exclu- sively for further industrial processing (so-called B2B devices). Thus the marking does not occur with the symbol of the crossed-out wheeled bin, but by the word mark and the date of manufacture.
The used semiconductors and components of the KEB Automation KG are developed and dimensioned for the use in industrial products. Restriction If the KEB COMBIVERT F5 is used in machines, which work under exceptional condi- tions or if essential functions, life-supporting measures or an extraordinary safety step must be fulfilled, the necessary reliability and security must be ensured by the machine builder.

UNIT DATA OF THe 400V UNITS 3.2.3.1 Overload characteristic (OL) All drive converters can be operated at rated switching frequency with an utilization of 150 % for 60 s. Restrictions: • The thermal design of the heat sink is based on the rated current and the maximum surrounding temperature.
UNIT DATA OF THe 400V UNITS Operation in the range of the thermal overload limit Due to the high steepness of the overload characteristic, the duration of a permissible overload in this range cannot be determined exactly. Therefore, the design of the drive converter should be assumed to have a maximum overload time of 300 s.
UNIT DATA OF THe 400V UNITS The following characteristics indicate the permissible maximum current for the output frequency values 0 Hz, 3 Hz, 6 Hz, 10 Hz 25 Hz and 50 Hz. If the switching frequencies are different, there is an interpolation between the characteristics. Unit size 19 is repre- sented exemplary.
