Hi Ronald
whats the part number of the diode you have ?
John
Hi Ronald
any silicon small signal diode like the 1N4148 would do
a 1A rectifier diode like the 1N4001 to 1N4007 will be mechanically more robust

with a TB6560AHQ
I expect you will set the current to 75% ( 3.5 x 0.75 = 2.625A ) a bit less than the 2.8A but should be OK with 94 % of the motor torque
to get near to 1.4A for ...
Did you get a manual with the new board so you know if you can set the current to 2.8A ?
and do you have the manual for the old board to see what the motor curren was set to ?
the TB6560 IC used...
did you ever have the machine working ?

provided the sensor has an NPN open collector output so there is no components connecting the + supply to the output
you can check this by powering the sensor and measuring the voltage between...
Hi Ronald
use the 24V supply as the G540's 48V supply is more than the sensors 6 - 36V supply range
as the sensor has a N/C NPN output you can only connect one sensor directly to each...
yes you have 2 wires connected to terminal 24 -
the connection to A1 via the E-stop and power to the spindle controller and DC power supplies

Hi Michael
on the KJD17 switch terminal A1 needs to be connected to terminal 24 via one of the E-stop N/C contacts
the second E-stop N/C is connected between the BOB E-stop input ( usually...
why not a 48V relay ?
then you can use the G540's 48V supply
what are you controlling with the relay ?
John
yet another version of an E-stop switch with just 3 terminals - a common . N/C and N/O
with this switch you can either connect it to the KJD17 terminals to kill the mains supply
or to the...
assuming you have the KJD17
a N/C E-stop switch can be wired between the KJD17 terminals A1 and 24 to remotely switch off the KJD17 and kill the mains supply to the machine
if you...
to use isolated input 11
you need to connect 11+ to the +24V supply and 11- to the - 24V supply
your limit switch needs to either break the +24V 0r - 24V connection
this example...
Thanks gerry
looking at the advert linked to
Motor control output port

this is an example of another Chinese BOB that I reverse engineered a while ago

Hi Michael
it is still a work in progress but is a wiring diagram for the spindle
if your not using a charge pump

note- the BOB shown needs a 5V supply from a USB port

Hi Michael
Its going to take a little time to produce a wiring diagram for the connections of the contactor to the spindle motor speed control / power supply
provided the relay can cope...
post 101 - the green box is a mains powered load switched on & off by the relay
in the diagram its shown as a pump but in your case it can be the speed control for the spindle motor

the next question is does the pin number next to the LED agree with pin you have assigned to that switch possition ?

it looks very like your BOB but takes a 5V supply from the PC instead of having a DC/DC converter to produce an isolated 5V dc...
looking at the manual for the C22 Rev 4.3 pendant interface I see it has LED to indicate the state of the inputs
do they confirm the switch status changes when you chang the switch positions ?

From what I can see from the photos
it looks like the wiring is correct
the main thing is the printer port adaptor is set up correctly with pins 2 to 9 set up as inputs
If its like the...
