Hi there,
We are confronted with a phenomenon where after a while (about 2min) on constant speed and torque the ACOPOS-P3 UDC_ACT (= the DC-BUS Voltage) breaks down.
I would expect that the supply on the Acopos terminals goes directly to the rectifiers to create the DC Bus Voltage. So either you’re drawing more current than can be rectified and smoothed (unlikely) or the supply to the Acopos is throttled or isn’t stable. Check the supply cabling for correct size and tight connection.
I’d suggest clamping an Amperemeter to each one of the phases in turn (one by one).
