Validity And Liability; Copyright; Specified Application; Standard Operation - KEB COMBIVERT R6-S Series Instruction Manual

1.3

Validity and liability

Application and use of our units in the target products is outside of our control and therefore is exclu-
sively the responsibility of the machine manufacturer.
The information contained in the technical documentation, as well as any user-specific advice in spoken and
written communication are made to best of our knowledge and information about the application. However, they
are considered for information only without responsibility. This also applies to any violation of industrial property
rights of a third-party.
Selection of our units in view of their suitability for the intended use must be done generally by the user.
Inspections and tests can only be done by the machine manufacturer within the framework of the application.
Inspections and tests must be repeated, even if only parts of hardware, software, or the unit adjustment are
modified.
Unauthorized opening and improper tampering can lead to bodily injuries or liability issues and this causes loss
of the warranty. Only use original spare parts and authorized accessories by the manufacturer. The use of other
parts excludes liability for the consequences arising out of such use.
The suspension of liability is valid also for shutdown damages, lost profit, data loss, or other consequential dam-
ages. This is also valid if we have referred to the possibility of such damages.
Should any part of this agreement be invalid for any reason, it is to be replaced with a corresponding text, which
is valid and equivalent to the intended meaning. The rest of the agreement shall remain unaffected and valid.

1.5

Specified application

The COMBIVERT R6-S serves exclusively for the supply of frequency inverters with DC input and/or regenera-
tion of excess energy into the supply system. The operation of other electrical loads is prohibited and can lead
to malfunctions or destruction of the unit.
The used semiconductors and components of KEB are developed and dimensioned for use in industrial prod-
ucts. If the product is used in machines, which work under exceptional conditions 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 manufacturer. The operation of our products outside the indicated limit values of the
technical data leads to the loss of any liability claims.
All control card outputs of the R6 are „one-channel, no diagnostic coverage and therefore not safe" according to
ISO 13849. If required, additional protective measures must be met by the user.
1.5.1

Standard operation

If the DC Bus voltage increases to a value above the peak value of the line voltage (negative power), regeneration
of the current to the line occurs automatically. The line voltage is measured by the R6 unit. Regeneration
occurs in a square-wave format, whereby the current flow period corresponds to the line frequency and the
normal conduction times of a standard 6 pulse bridge rectifier circuit. Regeneration stops if the DC bus voltage
decreases below the line supply peak voltage (positive power).
