3. Cable
– RS232 connecting cable
Cable between the PG/PC and interface converter
(cable diagram: refer to Chapter 2.5)
– RS485 connecting cable
Cable between the RS232/RS485 interface converter and the
nodes to establish an RS485 link
(cable diagram: refer to Chapter 2.5 or Fig. 3-10)
4. Terminating resistor for the RS485 bus
Generally applies:
First and last node ––> terminating resistor switched–in
Other nodes on the bus ––> terminating resistor switched–out
(switch S1, refer to Chapter 1.3.2)
Communications from a PG/PC to 3 ”SIMODRIVE 611 universal” con-
trol boards (2–axis versions) should be possible via the serial interface.
Online operation between a PG/PC and the individual control boards
must be realized via an RS232/RS485 converter and the appropriate
cabling on the RS485 side, so that the drive can go online at any time.
Assumptions for the example:
The recommended RS232/RS485 converter is used (PC/PPI cable).
Set all of the switches at the converter to ”0”.
The serial interface must be set to RS485 for all drives (P0801 = 1).
Setting the drive number (P0802)
– 1st board Drive A: Drive number for RS485 = 4
Drive B: Drive number for RS485 = 2
– 2nd board Drive A: Drive number for RS485 = 7
Drive B: Drive number for RS485 = 8
– 3rd board Drive A: Drive number for RS485 = 5
Drive B: Drive number for RS485 = 3
Terminating resistor for the RS485 bus
– Interface converter: First node
––> Switch–in the terminating resistor
or solder into the socket (refer to Fig. 3-10)
– 1st and 2nd board: No first or last node
––> Switch–out the terminating resistor
– 3rd board: Last node
––> Switch–in the terminating resistor
Example:
Communications
between the PG/PC
and 6 drives
via RS485
