4 Functional description

4.1 Control of the drive

The drive can be moved manually via the keys or digital inputs without upstream control. The

drive can be controlled and configured in the bus mode and via the service interface.

4.1.1 Operating modes

The following operating modes are distinguished: positioning mode and speed mode. In the

positioning mode there is the additional option of traveling in the inching mode. The position

control mode can be started via the digital inputs independent of the operating mode chosen.

4.1.1.1 Positioning mode

In the positioning mode, positioning to the specified set point is executed by means of a

ramp function (see Fig. 5: Ramp travel, direct positioning mode) calculated on the basis of

the actual position as well as the programmed controller parameters P (proportional factor), I

(integral factor), D (differential factor), acceleration and velocity.

Upon activation of the travel order, the actuator accelerates to the specified velocity with the

acceleration programmed. The measure of delay until reaching the setpoint is defined by the

parameter A-Pos (Object 2604h) as well.

Alternately, a value deviating from acceleration can be chosen for delay by means of

parameter D-Pos (Object 2606h).

Changing controller parameters during a positioning process does not influence the current

positioning operation.

The status word indicates whether the actual position is within the window defined by

parameter Pos Window (Object 260Ah). You can define the behavior of the actuator upon

reaching the programmed window via parameter Inpos Mode (Object 2616h).
