Installation of the drive connection

Connecting to ACS/ACH550

When using ACS/ACH550, SREA-01 can be connected by using the following

interfaces:

• Panel port of ACS/ACH550 (RS-232),

• Embedded Modbus connector of ACS/ACH550 (RS-485),

• RETA-01 Ethernet Adapter (Modbus TCP),

• RETA-02 Ethernet Adapter (Modbus TCP).

The usual scenarios are described below:

Only a single drive, not controlled through SREA-01 or by other fieldbus

Connect SREA-01 directly to the panel port by using the supplied cable and

connector X1/RS-232. If you want to use the panel simultaneously, you can also use

the Embedded Modbus of the drive and RS-485.

Only a single drive, controlled by other fieldbus such as PROFIBUS

Connect SREA-01 directly to the panel port by using the supplied cable and

connector X1/RS-232.

When other fieldbus control such as PROFIBUS is required, the Embedded Modbus

interface of the drive can not be used.

Only a single drive, controlled by a Modbus TCP client that connects to SREA-01

Connect SREA-01 to the Embedded Fieldbus of the drive by using RS-485, because

the panel port can not be used to feed the control word to the drive.

Multiple drives, not controlled by another fieldbus such as PROFIBUS

Connect SREA-01 to the Embedded Fieldbus of the drive by using RS-485. This

way the drives can also be controlled by Modbus TCP clients that connect to

SREA-01.

Multiple drives, fieldbus control such as PROFIBUS required

Connect RS-232/RS-485 converters to the panel ports of the drives and connect the

RS-485 Modbus network to the RS-485 interface of SREA-01.

When other fieldbus control such as PROFIBUS is required, the Embedded Modbus

interface of the drive can not be used.

The drive is equipped with the RETA-01 or RETA-02 Ethernet Adapter

Connect SREA-01 to the same network with RETA-01 or RETA-02 and configure

both modules to use Modbus TCP for communication.
