Building a 3 axis Vertical Milling Centre from scratch. 

Using  a CSMIO/IP-S motion controller, 750w simDrives and simCNC.  The wiring is based on the "csmio-ip-s-vs-simdrive-400w-750w-v2_rc2-simcnc-z-hamulcem.pdf".

Thought, I would bench test the controls & test a motor to get familiar with the setup before the final build.  I have double checked the wiring and the I/Ouputs configuration, which match the wiring diagram.  However when I try to enable the simCNC the following warning appears --  EMG:driver fault mod: CSMIO/IP0 mk index: 0, axis: x.    I have been informed that this means that the x-axis drive alarm is active and that I should connect to the drive and investigate so see what is wrong. 

Now here is were my inexperience shows, not sure what I should be looking out for.  I connected to the simDrive via a USB adapter and opened the Parameter Monitor.  This shows the alarm (Output.0).  However the only parameter that looks unstable is the Electrical Angle.  This became more erratic when I pressed the Alarm Rest Button (see attached screen shot). 

Is this normal or is there something else that may be causing the alarm?
