How to modify the BUS VOLTAGE ?

[wcx8229]

Hello,

Why is the bus voltage remain  about 330v when motor max-voltage is changed to 280v ?

the attchment is the status of Motor Pilot based on STEVAL-CTM010V1 .

Hello @wcx8229 

When Bus voltage sensing is enabled as it is your case for Motor 1, the value is read from the board and does not depend on the motor max-voltage.

How is your board powered?

Thanks for your support.

The power input is 220VAC 50HZ .

So could you tell me how can I get a 280v bus voltage ?

So steval_ctm0101v1 does not support 280V BLDC motor because of OVER VALTAGE ?

Just exactly how do you think this thing would be able to make a 280V bus voltage with a 220VAC input?
