Solved: maximal DC Voltage at XCS

stefanAT_ctrlX · ‎02-28-2023

Hello,

I have a XCS with an external brake resistor and a MS2N motor. The maximal DC voltage adjustment for the motor is 950V (P-853).

On the DC-Bus we have also an external equipment (load) which works with maximal 800V DC. Therefore I want to limit the DC output of the XCS drive. I can adjust the switch on limit for the resistor (P-834) to e.g. 730V but the P-853 (I adjust to 790V) will be set automatically while switching to OM to 950V (from the motor /encoder feedback). What can I do.

Regards, Stefan

There is no need to change the parameter P-0-0853 to a lower value than 950V. The bleeder will correctly be switched on at 730V as parameterized.
