AC OUTPUT
Requires firmware 2.0.0 or higher.
Extended operation from 1200Hz to 3000Hz supported at reduced maximum voltage. Some specifications
exceptions apply. Requires firmware version 1.6.2 or higher. Refer to Figure 4-3 on page 28 and Figure 4-4 on
page 29.
Note 4: FREQUENCY PROGRAM RESOLUTION FOR EXPORT MODELS (-4LE, -2LE):
Per U.S.A. Bureau of Industry and Security, ECCN 3A225, frequency control is limited to no better than 0.2% at
frequencies of 600 Hz. or more for unrestricted export products. To meet that requirement, frequency
programming in all -2LE and -4LE AFX models has three resolution ranges, which round the frequency to the
nearest increment, as defined in the table below.
Frequency Resolution for Export Models
Range
Resolution
1.00 - 99.99 Hz
0.01 Hz
100-599.9 Hz
0.1 Hz
600 - 999 Hz
2.0 Hz
1000 - 3000 Hz
5.0 Hz
Note 5: Refer to AC Mode Voltage / Current rating charts Figure 4-6, Figure 4-10, Figure 4-7 and Figure 4-11 on
following pages.
Note 6: Actual output phase angles may be slightly different from programmed values for highly unbalanced three
phase load conditions, in particular at high frequency due to amplifier phase shift differences.
