Kinetix 6000 torque limit

This is a previous post, I am realllly struggling to understand why I cannot set the torque limit on two out of a six axis system. I am writing to the torque limit bipolar with an SSV instruction but the actual torque on the axes just doesn't correspond. With zero written to the torque limit bipolar there is full torque on the axes. This only happens on two of the six axes, and they just happen to be 2094-BM01-S units as opposed to the other 4 being 2094-BM01 models. Any body had any similar problems?
The system consists of a CompactLogix L45 processor and two 1768-M04SE Sercos cards
