Solution fo "hm2 error finishing read" with no good PC

Category: Computers and Hardware

well, I'm trying to locate the trouble, it's with the encoders: when I unplug them, there doesn't seem to be any restarting, and when I plug them back in, the default comes back from time to time.

my encoder is power by 5V

Could it be the power supply or the encoder ground?

below, is the power supply for the 7i97t card too weak?

Servo tuning for an axis that behaves different in one direction versus the othe

Category: CNC Machines

I don't think so. It appears to just be a three phase brushless motor with integral encoder. Here is how the schematic shows the y-axis motor:
 

Looking up the part number, it is described as:
MHD041B-144-NP0-UN by Rexroth, Indramat, Bosch is a Synchronous Motor in the MHD Series. The MHD041B-144-NP0-UN features a Motor Frame Size of 82mm Flange Size, 50mm Centering Diameter and a Motor Frame Length of 2.7 Nm. This Motor has a Motor Encoder of Digital servo feedback and comes with a Output Shaft of Shaft with keyway according to DIN 6885-1 (with shaft sealing ring).

Thanks

Do the motors have tachometers? A dirty tachometer commutator might explain the behaviour

Look like more than just EMI causing lost Ethernet communications.

It actually it looks like the 7I97T card lost 5V power briefly,
since it does a full reset. I would check the 5V supply voltage,
current capability and connections.

In addition to tommylights suggestions, you might check that the contactor
contacts have arc suppressors, especially if they switch inductive loads.
