MCF8316A: Torque control mode

MCF8316A: MCF8316C_Torque Mode

hi,

Q1：Is there a register that can read the speed mode or torque mode status？

Q2：Why is it useless to change PWM control when the motor loses control in speed mode when modifying SPEED-LOOD0DIS=1 torque mode?

    You can see the state of the algorithm by referring to the ALGORITHM_STATE register.

    If you would like to know what speed/current value the algorithm is targeting while in the speed/torque loop modes you can refer to SPEED_REF_CLOSED_LOOP register for the speed reference when the device is in closed loop and IQ_REF_CLOSED_LOOP register can be referred to to see the current being targeted.

    Would you mind providing me more information on the issue you are seeing and what registers you are modifying?
