Chapter 12 Description of Parameter SettingsCT2000 Series
 It is possible that even when this parameter is being applied but the motor at the installation site
cannot go in to the "static status" caused by the inertia or by any external force. So, if the motor
doesn't go into a completer "static status" in 0.2 sec, increase appropriately this setting value.
 This parameter is functional only when the setting of Pr07-12 Speed Search during Startup ≠0.

 While forward run is starting, if there is a sudden reverse run and the reverse angle is bigger than
the Pr10-50 setting, then, drive will has a ScRv error.
 This parameter is valid only when Pr07-28 =11 Enable textile machine's function.

 This parameter is a High Frequency Injection Command when the motor drive is under IPM HFI
sensor-less control mode and it doesn't often need to be adjusted. But, if a motor's rated
frequency (i.e. 400Hz) is too close to the frequency setting of this parameter (i.e. 500Hz), the
accuracy of angles detected will be affected. Therefore, refer to the setting of Pr01-01 before
adjusting this parameter.

 This parameter is the High Frequency Injection Command's amplitude when the motor drive is
under IPM HFI sensor-less control mode.
 By increase the setting value of this parameter, the accuracy of angles detected will also be
increased. However, if the setting value is too big, it will cause a louder electromagnetic noise.
