7 3. Installing T he MDB-100 The MDB-100 connects to each drive via the drive’s communication por t , located on the right -hand side of t he drive enclosure under a small snap-on cover. Alt houg h no drive parameters need t o be config ured in order t o use t he MDB-100, it is advantageous to check that the dr ive’s communicat ion data rate is[...]

11 7. Netw or k Char acteristics Configura tion The MDB-100 interf ace board uses an 8-position DI P switch (labeled SW 1) t o config ure the Modbus network communication char act er ist ics. T he switch settings are only read during init ialization, so if a chang e is made to any of the switches on SW 1, t he MDB-100 must be r eset in order to ena[...]

15 9. Modicon Pr og ra mming 9.1 Supported Modbus Commands The MDB-100 interf ace supports 5 Modbus commands: comm and 1 ( 0x01: read coil status), com m and 3 ( 0x03: read holding reg isters), com m and 5 ( 0x05: f orce sing le coil), comm and 6 ( 0x06: pr eset sing le register ) and command 16 (0x10: pr eset multiple reg isters). Not all r egiste[...]

16 data will be the data obtained f rom reg isters 0xFE03, 0xFE04, 0xFE06, and 0xFD00 (in that order ) . Note that t he set t ings of t he pr og rammable address r egisters (0x6000 ∼ 0x601F) are stored in the MDB-100’s nonvolatile EEPROM. Ther ef ore, do not write t o any of these reg ister s m ore than 100,000 t imes. T ypically, these registe[...]

17 For setting 2 (coast stop) , the drive will coast stop (f r ee run) if it was running. T his action clears bit #10 in the select ed drive’s communication comm and bit st r uct ure (reg ister 0x7A00 / 0xFA00 - also the same data as write-only coil #10 / #26) and set s bit #11 (same as coil #11 / #27). Note t hat the “comm unicat ion command v[...]

18 The response delay time r value is read only upon MDB-100 initialization, req uiring the unit to be r eset if t he value is changed f or t he new value to tak e ef f ect . This setting is also non- volatile ( writt en t o t he MDB-100’s EEPROM). T her ef ore, do not write to this reg ister more t han 100, 000 times.[...]

19 10. Modbus Pr ogr amming Interface 10.1 Overview Three t ypes of Modbus data may be accessed via the MDB-100. These are holding register s ( 4x reference) , r ead-only coils (0x reference) and write- only coils (0x ref er ence) . In order t o access 2 dr ives within the allocated holding r eg ister map (0x0000 ∼ 0xFFFF), each drive is assigned[...]
