This parameter is a bit pattern that identifies drive error conditions
that are in addition to the shutdown faults in parameter 11. The
structure of parameter 129 is:
If any bit is true an error is indicated.
Bit 0 = + Software Overtravel - “+Sft ovrtrvl”
Bit 1 = - Software Overtravel - “-Sft ovrtrvl”
Bit 2 = + Hardware Overtravel “+Hrd ovrtrvl”
Bit 3 = - Hardware Overtravel “-Hrd ovrtrvl”
Bit 4 = Motor feedback loss - “Mtr fdbk los”
Bit 5 = Motor feedback noise - “Mtr fdbk nse”
