These outputs can control up to 4 axes simultaneously. Each output has an output level of 5V and can sink or source around 15mA per output. The maximum step frequency is 125Khz.
Not all motor drivers are capable of supporting step frequencies up to 125Khz. If you notice that the motors are not moving at all or show erratic movement, try to lower this frequency. Also, consult your motor driver datasheet for the supported frequency.
Please note, the WDo output is simultaneously switched for all axis at the same time. Depending on how the E-STOP hardware behavior is configured these outputs can be switched off in case of an E-STOP condition.
The WDo signal can be used to enable the drives or other devices. This signal becomes active when the drives are enabled in the software.
The TOOL output is used to activate the tool that is used in the application. This output is an Open Collector output.
Depending on the spindle driver, it might be necessary to use a relay to switch the tool on.
It is advisable to use a solid-state relay to switch on heavy loads like a spindle motor because this will also optically isolate this input again external interference signals.
The FLOOD/MIST outputs are outputs to control the flow of any coolants that might be used.
These outputs are Open Collector outputs.
If a large load is switched it is advisable to use a (solid-state) relay here as described in the TOOLON section
The CPU5A4(E) controller contains a 0-10V output, this output is combined with the PWM output. So, this output can only have one kind of signal. There is a jumper that can be used to configure the behavior of this output. The correct setting of this jumper is described in Jumpers & Indicators
The aforementioned jumper selects what signal is present on the output. Either 0-10V (default) or the standard PWM signal. These outputs use the existing PWM outputs of the board. If the PWM output is selected this output will be an Open Collector output.
This output is a generic output that can be used for any application. This output is an Open Collector output.
