7-6 Using Multi-Drive Mode
The example ladder logic program demonstrates using Multi-Drive
mode with five drives. See
Figure 7.2 for a system layout diagram.
Function of the Example Program
The example program provided is for the ControlLogix, but other
controllers can also be used. The following actions can be performed:
• View status information from the drives such as Ready, Fault, At
Speed, and Feedback.
• Control the drives using various Logic Command bits (Stop, Start,
etc.) and Reference.
• Perform a single parameter read and write for each drive. The
example uses drive Parameter 39 - [Accel Time] for both so you
can see (read) the change after a write is performed.
Adapter Settings for the Example Program
• The Mode Jumper on the adapter is set to the Multi-Drive operation
position. See Chapter 2 , Commissioning the Adapter .
• All DIP switches on the adapter are set to CLOSED (all 0’s). See
Chapter 2 , Commissioning the Adapter . The actual node address will
be set via a software parameter.
• The following adapter parameters are set:
Multi-Drive Ladder Logic Program Example
Parameter Value Description
02 - [DN Addr Cfg] 1 DeviceNet node address
15 - [DSI I/O Cfg] 4 “Drives 0-4” — 5 drives on 1 node
17 - [Drv 0 Addr]
(1)
(1) The settings for these parameters must match the Parameter A104 -
[Comm Node Addr] settings in the respective drives.
1 Modbus address of Drive 0
18 - [Drv 1 Addr] 2 Modbus address of Drive 1
19 - [Drv 2 Addr] 3 Modbus address of Drive 2
20 - [Drv 3 Addr] 4 Modbus address of Drive 3
21 - [Drv 4 Addr] 5 Modbus address of Drive 4
