IELDBUS PARAMETERIZATION

The following chapter describes briefly how to parameterise the AC drive in order for the motor to

be controllable via fieldbus. These instructions are written for basic applications. For more infor-

mation, consult the application-specific manual.

In order for the AC drive to accept commands from the fieldbus network, the control place of the AC

drive has to be set to fieldbus. The default value of the parameter "Control Place" is usually I/O.

Note that if the control unit firmware is updated, the default settings are restored. In addition, some

applications may have the remote speed reference selection set by default to other than fieldbus.

In these cases, the speed reference selection must be set to fieldbus, in order for the speed refer-

ence to be controlled via fieldbus.

NOTE! The motor control mode should be selected to support the used process and profile.

The navigation path to the fieldbus parameters may differ from application to application. The ex-

emplary paths below apply to the VACON

Basic information on how to use the control keypad you will find in the VACON

Application Manual.

Fieldbus control and basic reference selection

The following tables list some of the parameters related to fieldbus control in case of VACON

plications for the VACON

tailed information.

Parameters can be read and written by using the drive panel, PC Tool or fieldbus protocol. See

chapter 5.4.8 for reading and writing application parameters over PROFINET IO. Notice that some

of connections parameters for fieldbus may need to be set (depending on your configuration) via

panel or PC tool, before you can connect over fieldbus and write application parameters.

Torque control parametrization

Some extra parametrisation has to be made in order to control the frequency control with torque

control. The following instructions are for the VACON

more detailed information.

• Motor control mode (ID 600) should be configured to "Torque control" (2).

To configure the drive to use correct torque reference, select the parameter "Torque Reference Se-

lection" to ProcessDataIn1 (9). This can be done with: PC-tool or panel in panel tree: P 3.3.2.1, ID 64.
