5.14 Modulator
P773 Deadband Convert
The reversing threshold of the auto-reversing module (in rectifier direction)
If the (signed) setpoint of the DC link current (output of the DC link voltage
controller on the output side of the limiting module) exceeds
the value of +
0.05% set with this parameter, the firing pulses of the rectifier bridge are
enabled. These pulses are inhibited if the setpoint of the DC link current
drops below the value set here.

Deadband Invert
The reversing threshold of the auto-reversing module (in regenerating
direction)
If the (signed) setpoint of the DC link current (output of the DC link voltage
controller on the output side of the limiting module) exceeds
the value of -
0.05% set with this parameter, the firing pulses of the rectifier bridge are
enabled. These pulses are inhibited if the setpoint of the DC link current
drops below the value set here..

inbetween)
