I'm using Motor Control Workbench 5.4.4.20160 to build up code for motor control. There is a issue that In some specific situations, the dead zone will disappear, which can be seen in figures bellow. I give a constant d-axis current and force positioning the hEIAngle. If the hEIAngle is 0, the dead zone looks normal. But if the hEIAngle is set to 20479, then the dead zone disappear. Moreover, I run a continuous angle ramp and recorded the measurement results of the oscilloscope in the attached video. I have checked the register BDTR, it seems every bit is normal. Could you help me out for this issue?
Thank you for your kindly guidance.
