Its not a 7I97T limitation, it's a system limitation.
Analog servo drives for CNC do not use the analog voltage for position control
but rather torque or velocity control. This means the control system (LinuxCNC in this case)
MUST get position feedback from the axis or it cannot control the axis position.
The ECOdrive DKC11.3 can actually output both Incremental Encoder Output (A/B/Z Emulation) as well as SSI absolute encoder emulation. Will any of these fit the encoder input of mesa7i97?
Yes, if the the drive can output quadrature (A,B,Z) that can connect directly to the 7I97T's encoder inputs
SSI is also possible but would require an additional daughtercard, so quadrature is easier.
Quadrature A,B and Z should be the standard of the ecodrives position signal.
Could you direct me to some knowledge resources or forum threads related to the setup?
I've finally managed to configure my 7i97t with the mesaCT.
In order to test my card I tried to put a small voltage on the output pin of the analog 0.
I would have expected to be able to use something like
setp hm2_7i97.0.analogout0 1.0
but it seems that the parameter for the analog drives doesnt exist at all?
My firmware is 7i97_d.bin
Where did i get lost this time?
