Device-specific parameters

Code sequence

Behaviour of the position data in relation to the sense of rotation of the encoder shaft when looking at

flange.

CW („clockwise") = Ascending values with clockwise rotation

CCW („counter-clockwise") = Ascending values with counter-clockwise rotation

Class 4 functionality

If active („enabled"), the encoder operates as a Class 4 Device of the encoder profile.

If not active ( „disabled), the encoder operates as a Class 3 Device of the encoder profile.

Here setting a preset is disabled.

G1_XIST1 affected by preset

If active ("Yes"), setting a preset will affect both the left-aligned position value G1_XIST1 and the

right-aligned position value G1_XIST2.

If not active ("No"), the left-aligned position value G1_XIST1 is not added an offset that is internally

calculated upon setting a preset. In this case, both position values G1_XIST1 and G1_XIST2 may be

different!

Scaling function control

If active ("enabled"), resolution („steps per revolution", "measuring units per revolution") and the total

measuring range can be parameterized at will within the admissible limits.

If not active ("disabled"), the previous encoder settings for resolution and total measuring range will

remain, i.e. the maximum limits. Any try to enter deviating parameters will result in a parameterization

error signal.

Measuring units per revolution

Parameterization of the required resolution („steps per revolution", „measuring units per revolution").

Admissible values range from 1 to the maximum encoder resolution. Usually the limits are indicated

in the parameterization software.

multivoPlus encoders require a 32 bit value here to get two input fields, i.e. „measuring units per

revolution (hi)" and „(lo)". Ho to split the 32 bit value into two 16 bit values please see under 8.1.4.

A re-parameterization may clear the previous offset value (see "note" under 6.6. Preset function).

Total measuring range (units)

Parameterization of the required total measuring range, „TMR".

Singleturn encoders require here the same parameter as for the resolution ("Measuring units per

revolution").

Admissible values range from 2 to the product of programmed resolution multiplied by maximum

number of revolutions. The maximum limit of the parameterization software is only applicable if the

resolution is also the maximum.

All multiturn encoders and multivoPlus singleturn encoders need a 32 bit value here to get two input

fields, „Total measuring range (units) hi" and „lo". How to split up the 32 bit value into two 16 bit

values please see under 8.1.4.

Any alteration of the total measuring range clears the previous offset value (see "note" under 6.6

Preset Function)
