Current Utilization Of The Drive Motors - HEIDENHAIN iTNC 530 Service Manual

The I
equal to 0 are in the F-DC, T-DC, F-AC and T-AC columns of the motor or power module tables.
If the value 0 is entered in these columns, the following default values are valid:
In the power module table, all HEIDENHAIN inverters whose names do not end in "...-QAN"
