2. Safety notice

The Simple BOB CNC720 may only be installed and put into operation by electro-

tecnical qualied personnel. Please read the operating instructions carefully and

follow all instructions exactly. Improper installation or operation of the device can

damage the electronics or the machine and endanger the health of the

operating personnel.

Depending on the hazard potential of the machine, additional safety measures

may be required, such as door locking and standstill monitoring. Such safety functions usually have to be

implemented purely electromechanically with external circuits (not included in the scope of delivery) and

must not only depend on software and PC hardware. The system manufacturer who assembles the Simple

BOB CNC720 and other components to form the overall system, and the system operator are responsible

for compliance with the statutory provisions.

3. Connections

4. Functional description

4.1 Power supply (X-PWR)

The Simple BOB 720 is supplied with a DC voltage at the terminal X-PWR. By placing the Simple BOB 720

correctly on the EdingCNC720 controller board, the controller is supplied directly by the Simple BOB 720.

Please also read the EdingCNC manual in the actual version for further informations.

Pay attention to the polarity when connecting the supply voltage!

4.2 Motor driver control outputs (X-X, X-Y, X-Z, X-A)

The Simple BOB 720 can control up to 4 motor driver. The control signals for the drivers are provided via

the RJ45 sockets (X-X, X-Y, X-Z, X-A). Standard patch cables are to be used as connection cables. All

connections must be connected 1:1. You can nd the assignment in the table overview of the connections.

4.3 Reference switch inputs (X-REF 1 - 4)

Up to four referency switches (mechanical switches or inductive sensors) can be connected at the Simple

BOB 720. The reference switch inputs are connected at the 3-pole connection terminals (X-REF1, X-REF2,

X-REF3, XREF-4). Either normally closed (NC) or normally open (NO) contacts are possible as reference

switches. The polarity is set according to the type in the conguration of the EdingCNC software. A supply

voltage of 24V/DC is available for the reference switches.

When connecting inductive proximity switches, sensors with an operating voltage between 10 - 30V/DC

of type NPN or PNP must be used, depending on the setting of the jumpers (JP6-9) on the CPU CNC720.

Alternatively, simple mechanical switches can be installed. The home and ground pin of the respective con-

nection terminal must be closed or opened via the switch depending on the used type of switch.

Mixed operation of NPN and PNP sensors is not possible. That means, either all sensors are from

type NPN or PNP. Also the switching logic can only be either normally closed or normally open.The

CPU CNC720 ist set by default for NPN sensors.

4.4 Relay outputs (X-OUT)

With the Simple BOB 720 up to 4 relays can controlled:

• TOOL => Spindle on/ o󰀨

• FLOOD => Controlling of a ood cooling

• MIST => Controlling of a mist cooling

• AUX => programmable output via macro le

The Simple BOB 720 has several relays on the board. Relay K6 is switched depending on the Enable

signal, Relay K1 is switched synchronously with the output Tool for the spindle. The relay outputs are

designed for 24V/DC voltage levels.

Make sure that the relays have a coil voltage of 24V/DC and a built-in or externally connected revocery

diode.

The relay outputs switches ground, if they are activated by the software. That means +24V are permanently

applied to the relay coils (connection A1) and the relevant output is connected to the negative pole (connec-

tion A2) of the coil.

No consumers such as e.g. a solenoid valve may be connected directly!

4.5 Watchdog (X-ENA)

With the Simple BOB 720, the watchdog functionality of the EdingCNC CPU720 can be used to switch o󰀨

motor drivers, holding brakes and other actuators as long as the EdingCNC is not in the „Ready-state“.

Please read the activation of the watchdog in the manual of your EdingCNC. For this purpose, the potential-

free changeover contact of the on-board relay K6 is brought out on the 3-pin connector X-ENA, to which a

relay or contactor can be connected, which is switched depending on the state of the EdingCNC 720.

Terminal E2 is the common connection, terminal E1 the normally open and terminal E3 the normally closed.

In case of an error or if the watchdog does not supply a valid signal, the „DRIVE-ENABLED“ signal is also

deactivated at the controlling outputs from the axes.

The watchdog is not a replacement for a real emergency stop circuit!

4.6 Emergency stop (XSTOP)

An emergency stop button or a contact of an electromechanical emergency stop circuit must be connected

to the 2-pole terminal XSTOP. The behavior, normally closed or normally open circuit, can be congured in

the EdingCNC software, taking care of wire break safety. The emergency stop input signals an emergency

stop to the software, which then deactivates all outputs.

The watchdog is not a replacement for a real emergency stop circuit and must not be used as

this!

4.7 Speed control / Analog output (X-FU)

An analog signal 0..10V is output via the 4-pin connector X-FU, which can be used to control the speed of a

frequency converter.

In addition, the start / stop signal is forwarded to the frequency converter via the potential-free contact of

terminals 3 and 4 (K1 + K2).

4.8 Handwheel (X2)

EdingCNC has the option of connecting a handwheel for manual control of the milling machine.

(You can nd suitable handwheels in our shop).

The Simple BOB 720 connects the handwheel to the 9-pin SUB-D socket X2 outward. Please refer to your

handwheel manual for more information.

4.9 Tool length sensor (X-PRBEXT)

When using a tool length sensor, this is connected to the 9-pin SUB-D socket X-PRBEXT at pins 1, 2 and

3. The connection depends on the sensor type (mechanical or inductive NPN / PNP) and the conguration

of the jumper JP3 on the EdingCNC 720. In the delivery state, the input of the controller is set to NPN

logic. (see also jumper settings EdingCNC CPU 720 Chapter 5.3.1).

It can be used sensors as well with normally closed as normally open circuit.

4.10 External drive error (X-ALM-EXT)

In addition to the inputs via the RJ45 socket of the axes, the X-ALM-EXT connection terminal o󰀨ers a con-

nection option for drive monitoring. Depending on the jumper setting JP2 on the Simple BOB 720, either

GND or 5V/DC is switched.

4.11 External error input (EXTERR)

For monitoring attachments, pneumatics, etc., these can be connected to the EXTERR connection terminal.

The signaling devices must all have the same switching logic (normally closed/ normally open) and must

either be mechanical switches or optocouplers. In the software, depending on the logic setting at HIGH or

LOW level, the program is interrupted, the outputs are switched o󰀨 and an error message is generated.

4.12 External error output / Relay (X-EXTERR)

If there is an external error (see 4.11 External error) or a triggered axis error (function DriveError see 4.2

and 4.10), the built-in relay K5 is switched. The potential-free changeover contact of this relay is brought

out to the terminal X-EXTERR, with which the respective switching states can be monitored and evaluated.

Terminal XE-CM is the common connection, terminal XE-O the normally open and terminal XE-C the nor-

mally closed.

4.13 Voltage tap (X1)

The supply voltages 24V/DC, 5V/DC and GND for the internal wiring can be tapped at terminal X1.

4.14 Analog signals (X-FU1)

The X-FU1 terminal o󰀨ers the option of processing the two analog signals available from the CPU for vari-

ous applications. The supply voltage of 3.3V/DC and GND can be tapped directly here.

4.15 Internal Run / Pause (X-IRP)

Optionally, buttons for starting and stopping a CNC program, macros, etc. can be connected via the 4-pin

internal run / pause connection terminal IRP.

The buttons are already integrated in the handwheels from our shop. This connection option is intended for

the attachment of additional buttons / switches.

When connecting additional buttons, these should be implemented with closing contacts and the GND

should be switched to the relevant input. The signal is forwarded directly to EdingCNC software.

4.16 Spindle speed measurement (X-SP)

The actual spindle speed can be reported back to EdingCNC via the Simple BOB 720. The connection is

available using the 2-pin connector X-SP. For more information, please read the manual of your respective

EdingCNC.

4.17 External status LEDs

The red Micro-Match connector LED can be used to connect external LEDs with the appropriate mating

connector and a ribbon cable to display the di󰀨erent stages and errors. LED status boards with the mat-

ching mating connector are available in our shop ready for connection. The following stages will be issued:

LED Description Optional LED-Board

1grün Power supply switched on

2grün Ready for use (Watchdog)

3rot Error

4rot Emergency stop

5gelb Switching state Tool/ Spindle

6gelb Switching state Cooling (mist cooling or ood

cooling or both)

4.18 Holding brake

When using ball screws with a small pitch, smooth-running servomotors or very heavy Z-Axes, an electro-

mechanical holding brake should be used to prevent the vertical axis from dropping by itself when the drive

is switched o󰀨. Such brakes are usually operated with 24V/DC. They are blocked without voltage and open

when the voltage is switched on.

The brake must always be released as soon as the motors are energized, which can be achieved by using

the X-ENA connection terminal.
