EGM ERROR 50452: External Motion Interface cyclic error

Dear Sirs,

We are trying to test EGM path correction function implemented by our
Laser Vision camera.

Unfortunately we get:

EGM 50452: External Motion Interface cyclic error

When we send path correction messages of the type:

header {
seqno: 1
tm: 343434
mtype: MSGTYPE_PATH_CORRECTION
}
pathCorr {
pos {
x: 0.0
y: 0.0
z: 0.0
}
age: 157
}

pos.x is 0.0
pos.y in the range -17.0 + -17.0 mm;
pos.z in the range 50. -70. mm;

Do you have any other communication or sensor errors? In the manual, it describes probable causes for this error as:

“Communication with the External Motion Interface input source, for example a sensor or other device, has failed.”
