Counting Direction

This parameter counting direction defines whether the output code increases or decreases when the

shaft rotates clockwise.

Resolution

(positions per turns)

The parameter ‘resolution per revolution’ is used to program the desired number of steps per revolution.

Each value between 1 and the physical resolution per revolution can be programmed

Reset (RAX)

The preset value is the desired position value, which should be reached at a certain physical position of

the axis. The position value is set to the desired process value by the parameter preset

Velocity

The implemented software can additionally deliver the current velocity. This value is transmitted in

binary code, 16 Bit, in addition to the process value

It is possible to choose between four different units: steps per 10 ms, per 100 ms, per 1000 ms and

revolutions per minute

Software limit switches

function

Two software limit switches can be set. If the position value falls below the lower or exceeds the higher

limit switch, a status bit in the process value is set

PROGRAMMABLE PARAMETERS

INTERFACE

The Profibus-DP interface supports CLASS 1 and CLASS 2 functionality according to the encoder profile. In addition to these functions the GSD-file

supports further features, for example software limit switches. Further more, the following encoder parameters can be programmed directly via the

The rotary encoder is connected by two or three cables, depending on whether the power supply is integrated into

the bus cable or connected separately. If the power supply is integrated into the bus cable one of the cable glands

can be fitted with a plug. The cable glands are suitable for cable diameters from 6.5 up to 9 mm

The Profibus-DP device address is set by user-friendly rotary switches in the connection cap. Allowed addresses

are between 1 and 99, each can only be used once. The connection cap can easily be opened for installation by

removing the two cap screws

Termination resistors are integrated in the connection cap. These must be switched on if the encoder is connected
