Appendix B Out of Box Configuration for PowerFlex Drives
Setting the ACO/AVO
Attributefor PF527 Drives
Only
The attribute ACO/AVO (Analog Current Output/Analog Voltage Output)
can be used to set the analog output of the PowerFlex 527 drive to either
current (mA) or voltage (V).
Make sure that the Analog Out jumper (J2) is also set to the same value.

Table 73 - ACO/AVO: Values
IMPORTANT If your configuration includes a Rotary Permanent Magnet motor, you must
change the Phase-Loss limit to 1 ms for operation. If you do not change the
Phase-Loss limit to 1 ms, the Commutation Test for the Rotary PM could fail
and generate a Motor Phase-Loss Limit fault. Also, the instruction MSO for
the Rotary PM can fail and generate a Motor Phase-Loss Limit fault.
