3.2 Preventing Back Spin of Rotor During Startup

Option 1: Initial Position Detection (IPD):

  1. Go to Optimal Startup in the Optimization Wizards page, select IPD, and click the Next button for instructions to set up the IPD start up method.
  2. Set the IPD Advance Angle [IPD_ADV_ANGLE] to 90⁰ to get maximum startup torque. If there is sudden jerk observed during startup, then it is recommended to reduce the angle to 60⁰ or 30⁰ for a smoother startup.
Note:

Device triggers IPD timeout fault [IPD_T1_FAULT] for motors with very high inductance, or if the motor is not connected. If this fault gets triggered, it is recommended to check if motor is connected to the device.

Device triggers IPD Frequency fault [IPD_FREQ_FAULT] if the IPD clock frequency is set too high. If this fault gets triggered, it is recommended to decrease the IPD Clock value [IPD_CLK_FREQ].

Option 2: Slow First Cycle:

  1. Go to Optimal Startup in the Optimization Wizards page, select slow first cycle, and click the Next button for instructions to set up the slow first cycle startup method.
