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...
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...
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...
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.

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...
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...
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....
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...
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...
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...
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...
Lost steps is unlikely to be caused by RFI short of putting step and direction for multiple drivers into the same cable or operating next to a plasma or arc welding machine. If you suspect cross...
I would recommend the following connections.
HDBB2-RJ45......G214-CN2
1 (step).............2 (step
2 (dir)................3 (dir)
3 (gnd)..............1 (gnd)
4 no connect
5 no connect
6...
While the HDBB2 is powered by 12 VDC, its step and direction outputs
are conventional 5 volt logic levels.

Here is a 1200 oz-in motor that is slightly better, at 6 amperes, 5.1 mH, and 0.45 ohms.

Gecko has been sending out emails announcing a contest to get a free G214 driver, but I cannot find any information about this drive.
Does anyone know anything about it?

The PMDX-411 has been tested and is known to work with the G540 and Mach4, including
the charge pump and spindle speed control functions of the G540.
The PMDX-411 is a USB device. There is a...

Just in case anyone is seeking a similar solution that works with Mach4, have a look at this:

The G540 has opto isolators whose LED inputs have internal pull-ups to +12 volts.
Your sensor boards and the A180 device on them are strictly 5 volt devices. When
you tie their outputs to the...
Where can these 570 oz.in motors be purchased? The cable exit does not resemble any that I have seen advertized.
Thanks,

Both the G203V and the G251 use a common GND reference for the step and direction signals.
The G203V has an optically isolated common reference but the G251 signal GND is electrically connected to...
Unfortunately the G203V does not present an electrical signal
to indicate the error condition, so stopping the control system
in response to an error will be difficult. Possible work around
ideas...
From the standpoint of motor inductance versus power supply voltage, then the
theoretical speed relationship is linear. Double the voltage, double the speed.
Unfortunately other factors can come...
2 There is a trim pot to adjust for smoothness.... is this compensating for motor non-linearity?
Yes, it adjusts for motor magnetic linearity. Many people confuse this with
mid-band...
The power MOSFET transistors used in the G320 are rated for 100 volts maximum.
The G320 is rated at 80 volts in order to allow a little room to spare for safety.
Using a lower voltage will...
I really liked the metal cabinet that you had. Is the basic (unmachined)
cabinet a commercially available item?
Have you tried swapping motor/encoder between G320 drivers to see if the symptom follows the motor instead of the G320?
