Voyager™ III 520
Light Level
The user has the ability to adjust the intensity of the light pulses used on the fiber optic ring. This
feature is used to compensate for diminished signal due to issues such as ring distance. Low is the
default setting for Voyager III
Drive I/O
The user may select to use I/O options directly supported on the Drive Amplifier. Options are None,
Overtravel and Home Switches only or All I/O. Note: The Drive I/O will populate the general purpose
I/O (both analog and digital) in order from the lowest SERCOS drive axis to the highest SERCOS
drive axis. All I/O is the default setting for SMCC / Voyager III interface.
RECO I/O at Address 50
This parameter is set to Yes if the Indramat RECO I/O module is being used to expand the total
number of I/O being used on the standard fiber optic ring. Note: The RECO I/O will populate the
general purpose I/O (both analog and digital) following all drive I/O. The default setting for Voyager III
is NO.
HTA I/O at Address 70
This parameter is set to Yes if one of the SERCOS to Analog cards is set to be used for I/O
expansion.
