MCT8329A: Necessity of Gain Multiplication for actual value of DC bus current of inverter.

Tomofumi Okamoto

Part Number: MCT8329A

Hi team,

DC BUS CURRENT is measured in a motor system.

Is there a difference between the actual DC BUS CURRENT and the current value obtained from the address below, and is it necessary to multiply the value below by the CSA gain?

Hi Okamoto-san,

Thank you for your question! Today is a holiday in the US, but a member of our team will aim to provide a response by the end of the week.

Hi Okamoto-san,

The value in the DC_BUS_CURR register is the measured value of the actual DC bus current. To convert the value within the DC_BUS_CURR register to amps you need to divide the value within the register by 256 you do not need to also multiply the value by the CSA gain.

Joshua
