Set parameter 120.12 Run enable 1 to On.
Set parameter 122.01 User Power ref to 0 A.
Set current limits to low values, for example,
• 130.119 Minimum current to -50 A.
• 130.120 Maximum current to 50 A.
Press the control panel Start key to start the converter. After start, increase slowly the value of para-
meter 122.01 User Power ref.
Check the following signals:
• 102.01 DC voltage
• 102.02 ES voltage used
• 102.08 Total current
• 102.11 Modulation index %
• 130.101 DDC limit word 1.
