  • Page 4: Introduction

    While these things will help us achieve a better result, using a control board designed for industrial applications can be more important. MachBob3 (MB3) is designed for industrial application and specifically to work with the Ethernet Smooth Stepper (ESS) which is an excellent motion control board designed to be used with...

  • Page 5: Precaution

    This allows ESS to be mounted on MB3 directly without any ribbon cables. This makes the ESS easier to install and reduces the number of contact points, signals trace distance, inductance and resistance between ESS and MB3 board. As a result, all signals are less likely to be affected by noise and distortion.

  • Page 6: Quick Reference

    Table 1, Ports and Pins Reference Tables Quick Reference is a summary for the experienced users. Figure 1 is a shrinkage view of MB3 board. It shows the connection of inputs & outputs, power supply, analog output for the VFD and axis signals.

  • Page 8: Ess And Mb3 Piggyback

    ESS and MB3 piggyback The ESS receives its 5Vdc power from the MB3 when all three jumpers of ESS are closed, which is the default setting. But you may need to change the jumpers do so before you install. This eliminates the need for an external 5Vdc supply.

  • Page 12: Power Supply

    Configurator Utility. Power Supply The MB3 needs only a single 24Vdc power supply to operate the board. Figure 7, shows power supply input terminals for 0V and 24V. The 24V, 3A power supply is recommended for general usage.

    Placing terminals or ground lugs close to the MB3 makes for neater wiring to land shields and 0 or 5/24Vdc. The neater your wiring the easier to work with or add to. You should also consider the whole wiring scheme before wiring as you do not want to continually cross wires as this makes for a rats nest.

    On the left side is NPN input type which connects a switch between input X203 and 0V. On the right side is PNP input type which connects a switch between input X203 and power source 24V or 5V. www.CNCRoom.com Page 15...
  • Page 16 Figure 12 shows the 4 different methods to connect a switch with external power supply. These connections are totally isolated from any part of the MB3 circuit. The external circuits, for instance, could be the fault output of a VFD drive or plasma cutting system, where rough interference noise appears on the device.

    Figure 19, connecting various loads to a “Y” output Relays The MB3 comes with three relays; those are K1, K2 and K3. All relays provide NO or NC contacts. The K1, K2 also provides an “OFF Delay” feature. To activate this feature the user needs to follow the instructions as set out on page 24 , topic [*4].

    Small Adjustment Figure 23, Analog output adjustment POT Even though the MB3 board has been fully tested and calibrated before shipping. The suitable analog output may be slightly different from the actual with any VFD. There is a multi-turn POT (Potentiometer) that allows us to gradually shift the whole range of actual-line up or down over command-line by mV unit as appears in Figure 23.

    OK signal to the next device. However, if there is an error feeding in, MB3 will send out a “Not OK” signal by de- energizing the OSSD output and the external safety circuit will cut power and stop the hazard.

  • Page 23: Modification

    Modification Solder Bridges The MB3 has a number of places where the user can conduct modifications. Instead of using pin jumpers, solder bridges have been implemented to save cost and space. The user needs to solder or de-solder these bridges to achieve their purpose.

  • Page 24: [*2]. Safety Circuit Inputs

    This can happen after the control signal or the main power is cut from its drive. Solder the bridge at K1 to enable an off delay of 440 ms, or at K2 for 660 ms. Figure 29, Off time delay Solder Bridge for K1 and K2 www.CNCRoom.com Page 24...

    Normally, K3 Relay is associated with output Y101. However, you can select K3 as an output relay of CP (charge pump) signal or Y317. Please be careful of this 3 way bridge selection. Make sure that you bridge only one position at a time. www.CNCRoom.com Page 25 Figure 32, K3 Pin select solder bridge.

    Figure 33, PWM analog output solder bridge [*9]. Isolated Outputs Normally, MB3 provides high current transistor outputs. However, these outputs are slow, yet share common ground with other parts of the circuit board. In some circumstances, the user may need faster output or perhaps isolated output to interface with external device such as digital inputs of VFD which high voltage or noise interference running around them.

  • Page 56: Safety Circuit 3

    Safety Circuit 3 Since the MB3 board supports an “Off-Delay” function for relay K1 and K2, it allows the user to create a timing sequence for devices that need to power up or power down independently at different times. In this circuit an AC line monitor for recognising a “Power-Out” or “Black-Out” condition has also been introduced.
