12-173

FOC Gain of Excitation Current Rise Time

Factory Setting:100

Settings 33~100% Tr (Tr: rotor time constant)

 This parameter sets the drive’s excitation current rise time when activates at senslorless torque

mode. When the drive’s activation time is too long at torque mode, please adjust this parameter to

a shorter time constant.

Top Limit of Frequency Deviation

Factory Setting: 20.00

Settings 0.00~100.00Hz

 Pr.10-29 is for setting the maximum of frequency deviation.

 When this parameter is set too large, resulting in abnormal PG feedback malfunction.

 If customer application require a large Pr10-29 value, resulting in larger output slip, then it is tends

to be PG Error (PGF3, PGF4) in such a case. To prevent PGF3 and PGF4 error, set Pr10-10

Encoder Stall Level and to 10-13 Encoder Slip Range to be 0 "No function" (means removing

PGF3 and PGF4 detection). But this must only when the PG card connection and application are

correct, or prompt PG protection function will be disable. Too large Pr10-29 setting is not a

common set.

Resolver Pole Pair

Factory Setting: 1

Settings 1~50

 To use Pr.10-30 function, user must set Pr.10-00=3(Resolver Encoder) first.
