1-6 Getting Started
Benefits of Multi-Drive mode include:
Lower hardware costs. Only one 1769-SM2 is needed for up to five
PowerFlex 4-Class drives per channel (15 total).
Controller can independently control, monitor, and read/write
parameters for all five drives on each channel (same functionality as
Single mode).
The trade-offs of Multi-Drive mode include:
Since the RS-485 ports are used for daisy-chaining the drives,
additional DSI peripheral devices cannot be used with the drives.
This includes an optional, external PowerFlex 4-Class HIM
(22-HIM-A3 or 22-HIM-C2S) or a 22-SCM-232 Serial Converter
module with a software tool. The AK-U0-RJ45-SC1 DSI Splitter
cable cannot be used to add a second connection for a DSI peripheral
device.
The 1769-SM2 module is compatible with Allen-Bradley PowerFlex
4-Class (Component class) drives and other products that support DSI.
At the time of publication, compatible products include:
PowerFlex 4 drives
PowerFlex 4M drives
PowerFlex 40 drives
PowerFlex 40P drives
PowerFlex 400 drives
When the 1769-SM2 is used in Multi-Drive as a Modbus RTU Master,
other Modbus RTU Slave devices, such as PowerFlex 7-Class drives
with 20-COMM-H RS485 HVAC adapters, can also be connected.
