Digitax ST has a dedicated hardware enable/SAFE TORQUE OFF (SECURE DISABLE) input which always controls Pr 6.29. If the enable is inactive
the IGBT firing signals are turned off without software intervention. As default (Pr 8.10 = 0) the drive is in the inhibit mode when the enable is inactive.
Setting this parameter to one causes the enable to behave as an Et trip input. When the input becomes inactive an Et trip is initiated. This does not
affect Pr 10.32 (Et trip parameter), therefore an Et trip can be initiated in this mode either by making the enable inactive or setting Pr 10.32 to one.
