Configuration
SPD BND submenu
You can define up to seven speed bands in the 6652 DSP. For each band, you can define the
alarms and relay behavior when the machine speed is within that band. The SPD BND
submenu has the following options:
For more information on speed bands, see “Understanding Speed Bands” on page 38.
CHECK SPEED BANDS message
Note:
The options that cause this message are on the RPM 1-3 and the RPM 4-6 submenus.
However, the message does not appear until you try to exit the SPD BND submenu.
If you see the “CHECK SPEED BANDS” message when you try to exit the SPD BND
submenu, it means that you have set at least one of the speed bands incorrectly. There are
three possible causes for this message.
l
You have set the range for a speed band on the RPM 1-3 or RPM 4-6 submenus so that
the RPM LO value is greater than the RPM HI value for the band. The RPM LO setting
must be less than the RPM HI setting for a band.
l
You have set the range for two speed bands on the RPM 1-3 or RPM 4-6 submenus so
that the bands overlap. For example, if you set RPM1 HI to 200 and then set RPM2 LO
to 200 or less, the 6652 DSP displays the “CHECK SPEED BANDS” message. In this
case, RPM2 LO must be 201 or greater.
l
You have increased the number of active speed bands in the BANDS option on the SPD
BND submenu. This can cause the message to appear if the newly active speed bands
are invalid as described above, even though you did not change any of the band
settings.
You cannot exit the SPD BND submenu until the settings for all the active speed bands are
correct.
