Motor Control ICs Forum Discussions
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?
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.
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?
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.Show Less
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.
- Is there a guide that explains the process of tuning a BLDC motor using MCEDesigner?
- 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.
- 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!Show Less
I am trying to use a USB to UART converter, connecting it to TX/RX 0 and program the imc102T with the MCEDesigner.
Normally, i can do it without a problem when the parameters are not in the imc102t. But after programing the firmware parameters, if i try to program it again, it gives the following error:
To program again i need to follow this instructions,Solved: imc102 i motion link communication problem - Infineon Developer Community, to get this message to program parameters file:
1 - Someone has a clue why this is happening? and how can i solve it?
2 - Is the Debugger in the board doing something more to download the firmware and parameters?
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.
