The following chart is the collector voltage wave form of IGBT at high current turn off.
This drive unit has collector clamp circuit built in.
As for this clamp circuit, there is effectiveness to control the surge voltage on collector at high current turn off,
but the surge voltage may go over the maximum rating of collector voltage depending on the condition of use.
Therefore please confirm it in the actual machine evaluation.
Finally each parameter must be the following relation. Please keep this condition.

VDC_Link < Vosc_peak < Vz < Voff_surge
