Hello,

I am developing a product using iMotion to control 5 different induction motors with PFC. 

With that i have some questions:

1 - Can i change the specified AC input frequency in some way, allowing me to run PFC for all motors in 50 hz and 60 hz? Or can i only change it in MCEWizard because it is a static parameter?

2 - I know that i can put 45Hz to 65 Hz, and that way it would work for both. It would have a negative effect in the PFC working?

3 - Changing the specified input frequency will cause the pfc to work diferently with the same motors?

4 - Rotor lock fault will work on open loop control?

5 - Phase Loss fault can be used on induction motors, activating the parking startup?

Best Regards,

Paulo

I am trying to configure an imc101 to drive a BLDC compressor.
I think my configuration is correct, but the motor is not able to start.

I am attaching my current configuration, and the schematic.

Kind regards,

Hello.

I have two questions regarding the application note "EVAL_6EDL7141_TRAP_1SH".

There are three large electrolytic capacitors mounted on the evaluation board, but how do you determine the capacitance?
What is the role of this capacitor?

Best Regards.

Hi

I used Imotion IMC100 series and I plan to put a software lock on it. Is it possible to create a software lock on IMC100 series so that other people cannot program it or access its information? How should I do this? please guide me.

I am using the EVAL-M1-IM828-A and EVAL-M1-101T to prototype a BLDC motor application with sensorless control and open loop start-up. 

I am having some difficulty in tuning my motor. The motor accelerates smoothly to the “minimum running speed” set in question 9 in MCEWizard. Once it reaches this speed, the motor stalls. It shudders / turns very slowly for a few seconds after stalling before a gatekill fault shuts it down. I believe that this stall happens when the controller transitions from open loop to closed loop control.

1. Is there a guide that explains the process of tuning a BLDC motor using MCEDesigner?
2. MCEWizard gives three motor control mode options: speed control, voltage control, and current control. Can these be used to tune each of the control loops independently? The description above is what I observed when the motor was in speed control mode. In voltage control mode, the motor does not turn and trips a gatekill fault almost immediately.
3. I would like to use the scope features in MCEDesigner to monitor motor parameters while tuning. Some of the preconfigured traces work (for example, “Iu & MotorSpeed”), while others do not open. In particular, I would like to see a trace of target speed and actual speed, but any monitoring group with the TargetSpeed trace will not open.    

Thanks for your support!

请问一下，图片里魔术字是ABADCAFEH，这个值是示意值还是固定值？

i am reading the datasheet of TLE9183.and there is some description about crc3 in page 22 :

The CRC generator polynomial is x^3+x^1+1.The seed value is '101',hence the start value results in '100'

I have some questions:

①Is my calculation of start value correct？101 adds three zeros in the tails,and that is 101000.101000 divided by 1011（polynomial）and the remainder is 100,as start value.

②since we get the start value.How to calculate the crc for the original data ,bit by bit.

I would be very grateful if I could receive detailed guidance.
