3. Installing The MDB-100
The MDB-100 connects to each drive via the drive’s communication port, located on
the right-hand side of the drive enclosure under a small snap-on cover. Although no
drive parameters need to be configured in order to use the MDB-100, it is
advantageous to check that the drive’s communication data rate is set to its
maximum speed. Because the MDB-100 will communicate to each drive only at the
drive’s configured data rate, this will provide the fastest response time for drive-to-
Modbus network data transfers. For information on checking the drive’s
communication data rate, refer to the appropriate manual supplied with your drive.
Note that each drive’s communication data rate settings are independent of the
Modbus network data rate, which is configured solely by the Modbus network
characteristics switch (refer to section 7). Also note that the data communication
parameters of each drive are handled independently; the drive connected to Channel
A may simultaneously communicate to the MDB-100 at completely different baud
rates, parity settings, etc. than the drive connected to Channel B.
Installation of the MDB-100 Modbus RTU / ASCII interface should only be performed
by a qualified technician familiar with the maintenance and operation of the
connected drives. To install the MDB-100, complete the following steps:
1.
CAUTION!
Verify that all input power sources to the drives to be
connected have been turned OFF and are locked and tagged out.
2.
DANGER!
Wait at least 5 minutes for the drive’s electrolytic
capacitors to discharge before proceeding to the next step.
Do not touch any
internal parts with power applied to the drive, or for at least 5 minutes after
power to the drive has been removed. A hazard exists temporarily for
electrical shock even if the source power has been removed.
Verify that the
CHARGE LED has gone out before continuing the installation process.
3. Attach the MDB-100 to a sturdy, unmovable object (such as a wall) via the 2 case
mounting holes located on the tabs at the top and bottom of the enclosure.
4. Remove the drive’s communication port cover, located on the right-hand side of
the drive (as viewed when facing the drive), by pressing against the side of the
cover while sliding it toward the front of the drive. Do not discard this cover, as it
should be reinstalled if the MDB-100 unit is ever disconnected from the drive.
5. Connect the drive’s communication port to Channel A of the MDB-100 with the
communication cable (communication cable is not included with the MDB-100 kit).
When choosing cables for this connection, standard 24 AWG category-5 (CAT 5)
unshielded twisted-pair (UTP) 8-conductor cables found in ethernet networks in
most office environments can be used. The maximum allowable length for these
cables is 5 meters. Although there are many varieties and styles of CAT-5 UTP
cables available, ICC strongly recommends using only high-quality cables from
reputable manufacturers to guarantee optimal noise immunity and cable
longevity. Ensure that each end of the cable is fully seated into the modular
connector, and route the cable such that it is located well away from any drive
input power or motor wiring. Also take care to route the cable away from any
sharp edges or positions where it may be pinched.
