Multidrive Communication via RS232

Valid for S400, S600

Function

For controlling several servo amplifiers, start the communication with the first amplifier via RS232 and all other amplifiers via the CAN bus. Presumption for that is, that the CAN baud rates are identical and the station addresses of the servo amplifiers are set to different numbers.

Settings

Command

 Description

ADDR

Sets the address of the servo amplifier

CBAUD

Sets the CAN bus baudrate

COLDSTART

Resets the servo amplifier and reboots it for reloading the parameters out of the EEPROM.
The parameters ADDR and CBAUD are used only ofter a reboot.

SCAN

Counts the number of devices on the CAN bus and shows the addresses.

SAVE

Saves the setting to the EEPROM

Example

Communication with 3 x S600. Baudrate and station address of every servo amplifier is set via RS232 separately:

ASCII Commands:
CBAUD 500
ADDR 5 (7, 8)           {5 = 1. amplifier , 7 = 2. amplifier , 8 = 3. amplifier }
SAVE
COLDSTART

Connect servo amplifier 1 (address 5) via RS232 and the others via the CAN bus (Y adapter, e.g. SR6Y or SR6Y6, see Accessories Manual) for starting the multidrive communciation..

ASCII Commands:

SCAN

Scan amplifiers connected with the computer

Response :  2 7 8

"2 additional amplifiers are there, with addresses 7 and 8"

\ 7

select amplifier with address 7

\

which amplifier is selected?

Response: 7

Response: "amplifier 7 is selected"

\ 0

select the first amplifier (connected to RS232), here "Servo - Master" with the station address 5
