The 7I96S uses an Efinix FPGA so you would need the Efinix tool chain to make firmware for the 7i96S. 7 (P3) or 17. 00; Available Mesa Firmware - 7i96s + 7i85S 1PWM was created by spumco. As a newcomer to LinuxCNC and Mesa products I struggled to get may head around the 7C81 interface card and how it all fits together. And you can add a Mesa 7i85S to 7i96S and have 4 more stepper outputs, add a 7i84 and get 32 inputs and 16 outputs. The encoder pulse is just wired to the phase-A pin on the mesa card. I have a setup that consists of a Mesa 7i96 and a 7i85S and a Yaskawa Sigma II 30W Servodriver + Motor with incremental encoder. Encoder 00 has now become encoder 0 on the 7i85s board 5i25 7i85s 7i84 Connection and Configuration Start; Prev; 1; Next; End; 1; techrat; Offline; Junior Member More. The controller connection is a DB25 connector that 7i85S sserial - 7i73; ENC0 - subspindle (quadrature signal from drive output) appears as encoder. Yes there is a combination that PNCconf handles already, with this problem. Eine übliche Verwendung der 7i85 wäre der Anschluss von bis zu vier seriell angeschlossenen Antrieben an vier der fünf Vollduplex-RS-422-Schnittstellen der 7i85 und von bis zu vier Encodern Replied by Artur_1617 on topic Mesa 7i92+7i76+7i85S After install linuxcnc 2. The 7i85 is a five channel RS-422 serial plus four channel encoder interface for Mesa's Anything I/O series of FPGA interface cards. It appears to create the correct i/o types in Linuxcnc and does MESA 5i25 + 7i85S was created by shayloco. I am trying to do the same using a mesa 7i76 software encoder. Think to go with Mesa 7i92+7i85s but which card choose for I/O? Some Bob? Please Log in or Create an account to join the conversation. For example if you started with the hm2-stepper example files you would have a running config in a few minutes, and a halcmd show pins would list all available hardware for cutting and pasting into a custom hal file mesa 7i76e + 7i85s homing problem on 4th axis index-enable was created by Raban I have just finished mechanically and electrically installing the fourth axis, moved by an Asda B servo.

Replied by tommylight on topic Mesa 7i92 7i85s Hi, start to connect this setup for my lathe. Attached is a diagram of my vision for the electricals of the machine. I did write a 7i85S_7i78. I sorted some wiring issues that prevented me to control the axis manually. 2 hm2_eth: 10. The Mesa Configuration Tool creates LinuxCNC configuration files for 5i24, 5i25, 6i25, 7i76e, 7i80db, 7i80hd, 7i92, 7i92T, 7i93, 7i95, 7i96 Unused Mesa 7i85S was created by snowgoer540. Where can I start? Thinking of using Mesa 5i25 card in my computer control the system. I'm using a 7i96s + 7i85s card I'm pretty sure I'm using the correct firmware (downloaded from mesa).

I'm slowly getting the hang of this. Probably a 7I85S would be the best 5I25 daughtercard for a PWM/encoder setup. The 7i85 is designed for motion control applications. Thanks! EDIT: No Longer For Sale! A 7I85S version is available that replaces four of the serial interfaces with 8 differential ouputs that can be used as four differential step+ dir output pairs or PWM outputs or other output functions. I will probably have to add this one too. Hi, this is my first post here. INPUT CHARACTERISTICS. A common usage of the 7I85 would be connecting up to four serially interfaced drives to four of the 7I85s five full duplex RS-422 interfaces and up to four encoders with index to the 7I85s encoder inputs. I would like to add a 7i85S, When you order your 7i85S ask Mesa for instructions for doing what you want to do. But 7i92 to 7i85S I have problem. So far I got a lot of useful information for my project from this forum.
