MachMotion Apollo III 1000 Series Manual page 14

If the system does not use a VFD to control the spindle, a FWD/REV Contactor circuit can be used and is available from
MachMotion. Wire the spindle according to the diagram below. Notice that 24V is wired to the CW and CCW relay
contacts on the top row of the green terminals (the terminals on your Apollo board will likely be black, not green).

3.2 Spindle Configuration
3.2.1 Spindle Range Setup
For the control to know how to scale the analog voltage output, the maximum RPM for the spindle motor must be
defined.
If only one range will be used for your machine (no pulley adjustments or different gears), enter the minimum and
maximum RPM for the spindle in the Range "1" row.
If the machine has different ranges, the software can have multiple maximum speeds. The software uses a different
range for each different speed configuration. For example, one range could be set as 75 to 300 RPM for a low speed. A
medium speed range could go from 300 to 1200 RPM and high speed range could run from 1200 to 2400 RPM. The
control will output 10V when the Max RPM is called for any speed range. 0V is always at 0 RPM. In the example above,
the 1200 to 2400 range would output 5V at 1200 RPM.
To define the range(s), go to Configure->Control. Select the Spindle tab as shown below.
