Delta ac driver with acorn

[Quinn the eskimo]

I have Schneider electric ac servos and amplifiers and need help connecting to my new acorn. They were connected to a weihong ex23a3 which was fried when I bought this almost new 5x10 Chinese router table.

Is the delta asda-a2 the same as my Schneider electric lxm26du10m3x ?

The plugs and connections all look the same and the cn1 50 pin schematic are identical. Im trying to use the schematic for delta to acorn connection.

Another question. In a schematic, what is the difference between pulse and /pulse ? And or sign and /sign? That seems to be the only discrepancy between the delta and Schneider 50 pin cn1 plug drawings and acorn wants me to use pin 37 /sign and my pin 37 is just sign. My pin 36 is /sign
