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.
RDS parameter
PNU=305Hex; Type=O2; Scaling: 1Hex
P774 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..
RDS parameter
PNU=306Hex; Type=O2; Scaling: 1Hex
P775 Min Gating Angle
Alpha G limit (rectifier stability limit)
RDS parameter
PNU=307Hex; Type=O2; Scaling: 1Hex
P776 Max Gating Angle
Alpha W limit (inverter stability limit)
RDS parameter
PNU=308Hex; Type=O2; Scaling: 1Hex
P777 Max Gating Angle Ramp
Transition ramp of the alpha W limit from pulsating to continuous DC (for
currents < pulsating threshold, the control angle is limited to 165°, for
currents > (pulsating threshold+P777) to P776 with linear interpolation
inbetween)
RDS parameter
PNU=309Hex; Type=O2; Scaling: 1Hex
