Technical data

The compliance with power or current derating must already be considered
during the planning and dimensioning phase of the drive system.
If the feedback function is not available due to thermal overload, this may cause
a shutdown of the entire drive system.
The preset brake chopper threshold of the devices in the network must be
checked and adjusted.
The brake chopper threshold must be above the DC voltage in the regenerative
feedback mode. The following table shows the values for orientation for the
regenerative feedback mode at P
