Hi,
Our customer is considering to drive ERM by external PWM input.
Please tell me which registers must be set.
I think that the following procedure is necessary to make it an external PWM.
1. Power on
2. Turn EN to high
3. STANDBY bit = 0
At this point the device status is active
4. MODE[2:0] = 3
5. N_PWM_ANALOG = 1
When PWM is input at this point, the motor turns.
I think that they can check whether the motor moves at this point excepting control.
Is it correct?
Next step, I want to know the registers necessary for controlling ERM.
Are there any registers that must be changed from the default?
Best regards,
Tomoaki Yoshida
