Reverse angle limit (Electrical angle)
Settings 0.00~30.00 degree
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.
Injection Frequency
Settings 0~2000Hz
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.
Injection Magnitude
Settings 0.0~200.0V
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.
