The number 50849 in the error message shown above is not the error number! It is the axis position error
value expressed in pulses (it is the difference between the commanded position and the actual axis position).
On the other hand, if a few seconds after
switching Mach4 to the "Enable" state or af-
ter making a few millimeters of movement
using "Jog," the "PID Fault" error appears, it
will mean that the encoder counting direction is correct and the problem may be too low kP parameter value.
Such a situation can be caused, for example, by the influence of gravity on the Z axis, extremely heavy axis,
old dried grease on the guides. In this case, increase the kP parameter value by 0.01 and try again
If, despite using the "Encoder Reverse" option or increasing the kP parameter value several times, the above
visible error ("PID Fault") still appears, stop further attempts because the problem may lie in the configura-
tion of the servo drive or its connection.
When the effect is positive, i.e. the axis will perform slow motion orders given from the "Jog" level, and after
covering a longer distance, the "PID Fault" error will not appear, you can proceed to the next stage.
5) Switch Mach4 to "Enable" and press the "Auto", buton to automatically set the "Zero Offset" value.
The automatic configuration consists in entering
to the "Zero Offset" parameter the value of the
voltage generated by the DAC converter of the
CSMIO/IP-A controller when the position PID reg-
ulator is enabled and keeps zero revolutions of
the servomotor shaft. The necessity to use the +/-
10V analog signal offset results from the fact that
the servo drives should be turned on when the
voltage on their analog input +/- 10V corresponds to the zero rotational speed of the servomotor shaft. It
excludes unpleasant knocks and jerks of the axis when the "Enable #" signal switches on the servo drive.
If the "Zero Offset" parameter is higher than 0.5V or lower than -0.5V, first check if the analog ground be-
tween the CSMIO / IP-A controller and the servo drive is connected correctly. You should also check the
settings of the counterpart of the "Zero Offset" parameter in the servo settings.
