n8-66: Output Voltage Limit Output Filter Time Constant (for PM Motors)
There is normally no need to change this parameter from the default value.
Note:
1.
This parameter is only available in OLV/PM, AOLV/PM, and CLV/PM.
2.
This parameter is available in drive software versions PRG: 1017 and later.

n8-84: Initial Polarity Estimation Timeout Current
Sets the current to determine polarity for the initial polarity calculation as a percentage of the motor rated current.
Set the value in % unit (E5-03 = 100%)
Note:
1.
This parameter is only available in AOLV/PM and CLV/PM.
2.
If operating in AOLV/PM (A1-02 = 6) or CLV/PM (A1-02 = 7), the drive determines motor polarity by performing initial polarity
estimation when it starts the motor (this is done only the first time the motor is started when using CLV/PM).
The drive may begin operating in the wrong direction if it determines motor polarity incorrectly as the opposite direction of the Run
command.
Monitor U6-57 displays the deviation from the integrated current, making it possible to see if initial polarity estimation has successfully
determined the motor polarity.
3.
If an “Si” value is listed on a Yaskawa motor nameplate, set n8-84 to “Si” value x 2.
