2.2 Drive Specifications

2.2.1 AC-Line Considerations

Requirement Measures

1) Limiting the AC line symmetrical fault

current to 100 kA (max. for fuses) or

values acc. table below for UL, cUL, as

well as limiting commutation notches at

the line input (terminals 1U, 1V, 1W).

Always adding an impedance in the line input.

This can be a 3-phase line reactor with 2%

voltage drop minimum (refer to Table 8-6) or a

matched isolation transformer.

2) Limiting the A-C line symmetrical fault

current (RMS) at the field rectifier input

(terminals 3V, 3W) to 10 kA.

Adding a 1-phase line reactor acc. to Table 8-6.

Exception: No reactor is required when a

matched transformer is provided in the input to

the converter on drives up-to 450 A.

3) Minimum supply system (source)

capacity kVA.

Connecting to a source (supply transformer) with

minimum kVA rating acc. to the following table.

4) Limiting line transformer impedance to 4%

and continuous undervoltage to 10%.

Derating of armature voltage if impedance

exceeds 4% or continuous undervoltage.

5) Avoiding damage of drive components

due to overvoltage transients caused by

medium voltage switching on supply

transformers with a primary rating of 2300

VAC or more.

Providing additional input line conditioning on the

drive (e.g. Capacitance to ground).

Please Contact Rockwell Automation for

assistance when this is required.
