    Re: Laptop for Gecko controllers?

    The IBM/Lenovo T42 has an actual parallel port built into the laptop, so it can drive step and direction directly. I do not know if the I/O voltage on that port is 3.3 volt or 5 volt and that could...
  3. Re: How to use active proximity home switches with the G540?

    Somehow the sensors are getting a connection to the 5 VDC minus. It may be through chassis ground of the power supply, but is has to be there for the sensor to work.

    Also, yes NPN is required for...
  4. Re: How to use active proximity home switches with the G540?

    If you have the negative of your 5 VDC supply connected together with the negative supply of the G540, you have defeated the opto-isolation provided by the G540's interface. For desktop environments...
  5. Re: How to use active proximity home switches with the G540?

    It is fairly common for the sensors to work on 5 VDC under room temperature conditions, but I hesitated to recommend going outside the manufacturers specifications.

  6. Re: How to use active proximity home switches with the G540?

    The sensors must be NPN style to work with a G540

    The sensor's negative terminal shares the connection with the negative supply for the G540.

    The sensors you show allow input power between 10...

    Re: G540 Schematic seems wrong

    Yes, you should be using PWM mode for the output from Mach. You must also set the max spindle RPM to the correct value so that Mach knows how to compute the %PWM.

    The typical configuration is to...

    Re: G540 Schematic seems wrong

    The 10V from the VFD should always be there.

    When the speed is commanded to zero or an M5 is executed, the PWM signal will go away and the output voltage from the G540 should be close to zero....

    Re: G540 Schematic seems wrong

    The G540 requires a 10V reference FROM the VFD to be connected to pin 9 of the G540 terminal block. It does not produce a voltage by itself, it returns a voltage on pin 8 that is a regulated fraction...

    Re: G540 Schematic seems wrong

    Schematic drawing style is "unusual". The unregulated power source comes from the right side. The IR540N functions as a pre-regulator to feed a safe voltage into the 78L12. The IRF540N will be a...
  11. Re: Need some advice about wiring the Gecko G540 REV8 and Proximity Switch Sensor NPN

    To clarify, there is no need for a resistor in the Black lead from the sensor to the Inputs on Pins 1,2,3, and 4 of the G540.

    The NPN sensor output on the Black lead will conduct to the Blue...
  12. Re: Need some advice about wiring the Gecko G540 REV8 and Proximity Switch Sensor NPN

    Most proximity sensors are rated for 10 to 30 volts DC for power. If your motor power supply for the G540 on pin 11 is in this range, then you can connect the sensors without any resistor or other...

    are conventional 5 volt logic levels.
