Chapter 12 Description of Parameter Settings
FOC Minimum Stator Frequency
Settings
This parameter is used to set the minimum level of stator frequency at operation status. This
setting ensures the stability and accuracy of observer and avoid interferences from voltage,
current and motor parameter. fN is motor rated frequency.
FOC Low-pass Filter Time Constant
Settings
This parameter sets the low-pass filter time constant of a flux observer at start up. If the motor
can not be activated during the high-speed operation, please lower the setting in this parameter.
FOC Gain of Excitation Current Rise Time
Settings
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
Settings
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 the application need higher setting of Pr10-29, please note that: Higher setting of Pr10-29
value will result in larger motor slip, which will cause PG Error (PGF3, PGF4) easily. In this case,
set Pr10-10 and Pr10-13 as 0 will disable PGF3 and PGF4 detection, but it needs to make sure
the PG wiring and application is correct. Or it may lose the instant PG protection. Too Higher
Pr10-29 setting is not a common setting.
Resolver Pole Pair
Settings
To use Pr.10-30 function, user must set Pr.10-00=3(Resolver Encoder) first.
