Believe it or not, CNC11 v3.01 rev15 is older than CNC10 v2.70. To unlock options after you are at the main screen, go to the Machine Parameters screen: F1/Setup F3/Config "137" F3/Param Although F1/Unlock is not displayed, you can press F1 on the Parameters screen to enter software unlock...

Yes, that is the wiring in a nutshell: one side of each normally-open contact goes to an input point (one of pins 1-6) and the other side of the switch goes to 0V. If you are using the internal 5V supply you need to install the jumpers (J26 and J27, for H18) and install 470 ohm SIPs (as SIP1 and SIP...

In short: Use your E-stop contactor to guarantee that all moving things cannot move when E-stop is pressed. Use relay outputs on your PLC unit to turn the router on and off, through an intermediate relay or contactor. I.e. the relay output on the PLC switches whatever appropriate voltage to the rela...

I would guess you are fighting a chicken-and-egg problem with the standard PLC program logic. If the AMC drive reports a "fault" condition any time it is inhibited, then the PLC program probably won't let the GPIO4D enable the drive. It will want the drive fault to be "fixed" fir...

You set the speed in low range (vs. high range) with Machine Parameter #65. For example, if the spindle speed for a given motor speed in low gear is 1/8 the speed it would be in high gear, then you would set Parameter 65 to 0.125. The PLC program is responsible for applying this value, and also for ...

In your first post, it is unclear whether you are asking about a spindle brake (one that stops the tool from rotating) or a Z axis brake (one that prevents linear Z movement). The brake outputs on the GPIO4D control servo axis brakes. They are generally for use with servo motors that have integral h...

No. The DC3IOB is a single unit that incorporates three axis drives and a PLC I/O unit in a single unit. It is not modular. On the one hand, this means you can't change out just one drive, or just the PLC input section, or just the PLC output section, or.... On the other hand, it means you only need...

2500 sounds more like a line count (lines per rev, pulses per rev, cycles per rev...).

The effective counts per rev is 4x that amount. You need to enter 10000.

When you refer to the mill manual, I am guessing you mean the table under M94/M95 in Chapter 13. That table lists PLC inputs , not outputs. M94/4, for example, will turn on INP36 in the PLC program. What, if anything, the PLC program does in response depends entirely on your particular PLC program. ...

You have not said whether your systems have DOS and CNC7; Linux and CNC10; or are one of the handful running Windows and CNC7 or CNC10. I will assume you are using Linux and CNC10. In that case there is no separate PLC directory. Your PLC sources will be in the /cncroot/c/cnc10 directory, along with...
