1.The AMC 30A8 drive uses an active low “inhibit in” while the GPIO4D outputs an active high enable. In order to convert the active high enable to an active low inhibit the enable out is routed into a PLC input (IN 13) and back out a PLC output (Out13). When the control senses a fault condition, output 13 is turned on which pulls the “inhibit in” signal to ground and inhibits the drive.

2.The diagram above depicts the wiring for the first axis. When wiring additional axes, follow the I/O in sequence. Axis 2 should use IN14 and Out14, Axis 3 In15 & Out15 and axis 4 should use In16 and Out16 respectively.

3.Additional logic is needed in the PLC program to properly map the enables to the outputs and convert them to inhibits. This logic and installation instructions are included in the PLC program available for download from the link below: (looks like I won't get the link up until morning. Sorry for the inconvenience)

Should we tune the drive per AMC specs (i assume they have some) or are there some special tricks?

When we follow these instructions and use inputs 13 thru 15. What do we hook the 13-16 common to????????

You should follow the AMC docs to setup the drives to run in torque mode and the inital position of the pots and then follow the tuning procedure in the Ajax Mach operators manual.

Sorry, we missed that. Please see the updated drawing above.

Thanks for the rev.

Do you have a link to the new PLC programming/ brains needed?

Any luck on the Brains?

Thanks

Extract Ajax_AMC_Disables.brn from the attached file -Ajax_AMC_Disables.zip- and copy it to the brains directory in your mach install.

In Mach - select "Operator" ->"Brain Control" ->"Reload All Brains" then select Ajax_AMC_Disables.brn by clicking on it and check the box marked "Enable Brain" and click "Reload All Brains" again....

Remember, your drives should be enabled by default -these brains will allow you to explcitly disable the drive anytime the enables are taken away. You can use the "View Brains" feature to watch the behavior...

Regards
