Notice the lack of replies and the “100% loss”.
You have to be slightly careful with ping because you can successfully ping yourself! The output of ipconfig (step 1) tells you which IP
addresses are associated with your network adapters. Use this information to make sure that you are not pinging yourself and thinking that
you have just confirmed your connection with a UCC2.
“IP configure” software fails to run
If the PC is using a VPN ﴾virtual private network﴿ software such as “check point”, it will be necessary to disable the use of this software for the
network card dedicated for UCC use. This is carried out in ‘control panel’ / ‘network connections set‐up page’.
NOTE:
A reboot of the PC will be required before this change is implemented.
Motor stalling
Symptoms
The machine stops unexpectedly. The event should be reported as a fault by the user's program and may be identified as a stall on a specified
axis. ﴾The condition is reported to the application software by the controller's setting of one of the three ‘axis overdriven‘ flags in a status
report).
Possible causes, tests, cures
The problem may be due to unintentional contact between a moving part of the machine (not the probe's stylus) and some object. Correct
as required, checking for correct CMM calibration if a serious impact occurred.
Contact between cables or cable-chains and the machine structure may also be the cause, similarly lock-up may be due to cable creepage
through clamps and limiting travel.
Excessive friction can cause the problem due to a mechanical problem (low air pressure, contaminated bearings/ways, etc.). Drive the
machine slowly past the suspect region to localise the problem area. Correct as required.
Other factors may stop the machine such as the operation of limit switches, crash switches, air pressure switches, etc. These should be
reported as such by the application software. If not, confirm the effect using Renicis and request more detailed error reporting from the
application software.
Machine overspeed report
Symptoms
The event should be reported by the application software as an ‘overspeed‘ or similar wording.
﴾The condition is reported to the application software by the controller's setting of the ‘overspeed' flag in a status report.﴿ The servo drives, if
engaged, will be disengaged automatically by the controller.
Possible causes, tests, cures
Machine movement by hand ﴾with motors disengaged﴿ at speeds higher than the limit set by ‘max move speed' times the ‘overspeed
factor'. See the ‘move configuration' command. Avoid moving the machine too quickly by hand, or ensure that the application software
suppresses this warning if the motors are disengaged, provided that it is unlikely that the machine can be moved so quickly that the
controller counter circuit bandwidth limit is exceeded, see the ‘Specification' chapter of this manual.
Very high apparent speed due to initialisation with improper values of maximum speed or scale increment, or incorrect velocity or position
feedback signal polarities causing instability (normally only occurring if a machine configuration parameter is altered). See the sections in
UCC2 and UCC2-2 installation guide
