3. 7. Communication via Interbus network

3. 7. 1. Reminder of the possible connection methods: Same as existing

1	= DO2	4	= NC	7	= DI2
2	= DI2	5	= VCCO	8	= NC
3	= GNDO	6	= DO2/	9	= RBST

The profile used by the Altivar 61 in the CMD Tool bus configurator is compatible with that of the Altivar 38, i.e., DRIVECOM Type Profile 21 (RB) and, therefore, there is no difference in the process data.

Use the Altivar 61 control card’s external power supply function, as in the event of a break in the drive power supply all communication on the Interbus-S bus will cease.

3. 7. 2. Configuring the communication parameters

The drive is configured by default to communicate on the bus with limited services. The data exchanged on the bus is not transmitted to the drive.

On the display terminal, in the [1.9 COMMUNICATION] (COM-)menu, [COMMUNICATION CARD] (CBD-)submenu, the value of the [Address] (AdrC) parameter is 0.

To operate in normal mode, in which the data exchanged on the bus is transmitted to the drive by the INTERBUS card, the value of this [Address] (AdrC) parameter must be changed to 1.

Configuring the drive control mode

Check and configure the control mode applied to the drive in the [1.6 - COMMAND] (CtL-)menu on the graphic display terminal, the integrated display terminal or the PowerSuite software workshop.

[Profile] (CHCF) = [8 serie] (SE8)

3. 7. 3. PLC configuration and application

The fact of opening the Altivar 61’s "ATV38 compatibility" memory zone (SE8 mode) performed by the PowerSuite software workshop means that no changes need to be made in the PLC application.

However, in response to an "Identify" service request the drive will identify itself as an Altivar 61, not an Altivar 38.
