Software and protective functions
Description
Know-how protection
Know-how protection for encrypting stored data, e.g. to protect configuration know-how, and to protect against
changes and duplication (with password function).
Web server
The integrated web server provides information about the drive unit via its web pages. The web server is accessed
using an Internet browser via unsecured (http) or secured transmission (https).
Power unit protection
Description
Ground fault monitoring at the output
A ground fault at the output is detected by a total current monitor and results in shutdown in grounded systems.
Electronic short-circuit protection
at the output
A short-circuit at the output (e.g. at the converter output terminals, in the motor cable or in the motor terminal box) is
detected and the converter shuts down with a "fault".
Thermal overload protection
An alarm is issued first when the overtemperature threshold responds. If the temperature rises further, the device
either shuts down or independently adjusts the pulse frequency or output current so that a reduction in the thermal
load is achieved. Once the cause of the fault has been eliminated (e.g. cooling has been improved), the original oper-
ating values are automatically resumed.
