3. Connecting drive(s)
If you have a single ACS350, ACH550 or ACS550, it is easiest to
use the supplied RJ45 cable to connect to the panel port.
RX (RS-232)
TX (RS-232)
If you have multiple drives or an ACS800, use the RS-485
connection. Connect the A- channels of the SREA-01 unit and the
drives together, the B+ channels together and the COM connector
to the data ground connectors of the drives. Use 120 ohm
terminating resistors in the network.
4. Basic drive settings
Check the communication settings of the drive (either group 52 or
53 in most drives, depending on the connection type).
Station id/number has to be unique for each drive! The baud rate
selection and parity have to be same on all drives and
SREA-01. You can use for example 9600 bit/s, no parity, 1 stop bit.
5. Basic SREA-01 settings
You can change the Ethernet settings under Setup – Ethernet.
Select the correct drive connection settings under Setup –
Modbus.
• Select Physical Interface.
• Usually most other settings are suitable by default (RTU,
9600 bps, no parity, 1 stop bit).
