COOLANT output
The coolant output can be used to control any form of coolant that might be used during the
operation of the machine. Its output is electrically identical to the TOOL output. For information
about how to use this please refer to that part of the document.
5.3
STEP/DIRx output
The controller board features 3, optional 4, outputs for controlling the driver of a stepper motor. The
signals generated are the common signals STEP and DIRECTION, as used by many drivers.
The DIRECTION signal indicates to the driver whether it has the move clockwise (CW) of counter-
clockwise (CCW). The STEP signal indicates when a step is to be made. Figure 8 illustrates this.
Figure 8. Example of STEP/DIRECTION signal.
Whether the DIRECTION signal means CW or CCW depends on the stepper driver and how you wire
it or configure it. Also, whether the low/high or high/low signal indicates a step depends on the way
it is connected and used by the driver.
Please refer to you motor driver’s manual to find more info
rmation about how to connect the
controller to it.
5.4
AMP-ENABLE output
The AMP-ENABLE output is used for enabling the motor drivers. This output can supply more output
current than the other digital outputs.
