Sets the current to determine polarity for the initial polarity
calculation as a percentage of the motor rated current.
100% = Motor rated current
Note:
If an “Si” value is listed on a Yaskawa motor
nameplate, set n8-84 to “Si” value x 2.
Default: 100%
Min.: 0
Max.: 150
<1> Default setting is determined by parameter n8-72, Speed Estimation Method Selection.
When n8-72 = 0, default is 50.0
When n8-72 = 1, default is 150.0.
<2> Default setting is determined by parameter E5-01, Motor Code Selection.
<3> Values shown are specific to 200 V class drives. Double the value for 400 V class drives.
<4> Available in drive software versions PRG: 1017 and later.
