Statistical data
Under
Statistics, the TNC displays information about the
transmission quality.
If the reception quality is poor so that a proper and safe stop of the
axes cannot be ensured anymore, an emergency-stop reaction of
the wireless handwheel is triggered.
The displayed value
Max. successive lost indicates whether
reception quality is poor. If the TNC repeatedly displays values
greater than 2 during normal operation of the wireless handwheel
within the desired range of use, then there is a risk of an undesired
disconnection. This can be corrected by increasing the transmitter
power or by changing to another channel with less radio traffic.
If this occurs, try to improve the transmission quality by selecting
another channel (See "Setting the transmission channel", page 493)
or by increasing the transmitter power (See "Selecting the
transmitter power", page 493).
