Tom was probably thinking you meant #23401-#23408. Just out of curiosity, do #23401 and #23402 change state on your system, corresponding to whether or not the asterisk is showing? Yes, I think #25101-#25108 are relatively new. Presumably they were added to avoid the awkward timing issues you get wh...

This is largely a function of the PLC programming, and to a lesser extent VCP design. I agree that the subject needs to be revisited. In my opinion, the VCP "reset" button/box should have three display states: 1) Normal: the VCP reset is not set, and the emergency stop is not pressed. Cont...

Have you verified the analog voltage at the analog input to the Siemens drive? If you are getting a suitable analog signal there, then the Centroid software/parameters is doing what it is supposed to do. I do not immediately know what could be miswired or misconfigured with a Siemens 611 drive, to a...

Every machine is different. Not every machine is capable of orientation. M19 is just an external M function (a CNC macro that you, as the control integrator, provide). It does not get any special handling by CNC12. As such, there are no parameters (such as a "P" value) that can be passed i...

If you want to be able to swap the motor power leads back, then you could indeed swap the encoder polarity at the same time. It does not really matter which motor direction is positive and which is negative. All that matters is that the encoder feedback match the outgoing power: positive output curr...

Before selecting reversing contactors and an overload relay, you need to know the rated current of the ATC carousel motor. Take enough covers off that you can read the data plate. On other B5AC machines, these have been rated between 0.31A and 0.40A on 230VAC. I would use Fuji SC-E02 contactors and ...

No, transformers output only AC. Rectifiers convert AC into DC. The label on the old schematic is misleading (read: wrong). The taps that wires #90 and #91 connect to have about 180VAC between them; or about 90VAC from each one to the center tap (CT). On the old schematic, D1 and D2 are stud diodes....

Regarding "sourcing" and "sinking", it is important to be clear which side of the circuit you are talking about. Sourcing devices connect to sinking PLC inputs. Sinking devices connect to sourcing PLC inputs. Similarly, if you are using solid-state PLC outputs, then sourcing outp...

If the C axis rotates from a position of C-23.0 degrees to a position of C-60.0 degrees, then it is moving in the negative C direction. Let's say that is CCW from your viewpoint. Then when the C axis rotates from a position of C-60.0 degrees to a position of C-23.0 degrees, then it is moving in the ...

If the asterisk is always visible while you move the axis up and down the scale, then yes: you should try swapping the polarity of the index channel wires.
