Last thing related to the revs control is a choice of analog output, which
will be used.
•
select from the menu „Config/Config PlugIns”
•
click „CONFIG” next to the „CSMIO/IP”
•
go to „Spindle” tab, in the „Spindle DAC” group
•
select „Enable”
•
on the „Select Analog Output” list select analog output.
Again, during the startup the diagnostic window may be help-
ful. In the „Analog IO” tab, you can preview current voltages on
analog inputs and outputs. When we configure the spindle,
then in a MDI tab you can enter e.g. M3 (enter), S2000 (enter).
It should cause spindle activation (right revs) and setting the
revs on: 2000 rpm. In the diagnostic window, you can see digi-
tal outputs and voltage on analog output activated.
Additionally the icon informs us which analog input is config-
ured to control a spindle.
Check carefully inverter settings before spindle activation, incorrect configuration may cause perma-
nent damage of the spindle, which is not covered by warranty.
Pay attention if the left/right revs are activated correctly – machining with incorrect revs direction
may cause damage of a tool or a work piece.

Problematic PWM Control function
A frequent reason of problems with analog inputs is „PWM Control” option set in Mach3. On first
sight, sometimes we do not see this position is marked, especially when „Use Spindle Motor Output”
position is not active. Below you can see correct and incorrect settings.
If „PWM Control” is check-marked but inactive you must first mark “Use Spindle Motor Output”, then
click „Step/Dir Motor”, and again uncheck the „Use Spindle Motor Output”. Selecting „Step/Dir Mo-
tor” in this place does not mean that spindle will be controlled by STEP/DIR signals. Configuration of
a spindle as an axis you will perform in plugin. It is described later in this guide, chapter: “Additional
configuration functions in plugin’s window”.
The „PWM Control” option should be unchecked because it is incompatible with CSMIO/IP and leads
to errors during spindle revs control.
