4.6.1.

Encoder Class Selection

In encoder class 4, all parameter settings are enabled and affect configuration.

In encoder class 3 some parameters are permanently on default, regardless of the user configuration:

•

scaling is not enabled

•

the number of steps per revolution is fixed to the maximum of the respective basic encoder

•

total measuring range is fixed to the maximum of the respective basic encoder

•

rotation sense is fixed to cw

•

preset functionality not supported.

4.6.2.

Compatibility Mode

Compatibility mode according to encoder profile V3.1,

•

considers parameter „max. master life sign error"

•

„CR" bit in status word ZSW2 of the PROFIdrive telegrams is always „0".

•

control words and setpoints will be adopted, independent of the CP bit in Control Word STW2

•

preset will only affect position value G1_XIST2, not G1_XIST1.

4.6.3.

Measuring Units per Revolution

Configuration of singleturn resolution within the range from 1 on to the maximum encoder resolution.

Note: A change in resolution parameters clears the preset offset value (if any) so that the current

position reference will be lost. See also 6.6 "Preset function".

This setting will be taken into account in Encoder Class 4 only (see Abs. 5.6.1).

4.6.4.

Total measuring range

Parameterization of the required total measuring range „TMR".

With singleturn encoders, enter the same value here as for the "Measuring units per revolution"

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

encoder's maximum number of revolutions. See also 5.6.13 "Important Note for Multiturn Encoder

Operation".

Note: A change in "Total measuring Range" clears the preset offset value (if any) so that the current

position reference will be lost. See also 6.6 "Preset function".

This setting will be taken into account in Encoder Class 4 only (see Abs. 5.6.1).

4.6.5.

Code Sequence

Position data behavior relates to the rotation direction of the encoder shaft when looking at the

flange.

(„clockwise")

CCW („counter-clockwise")

This setting will be taken into account in Encoder Class 4 only (see Abs. 5.6.1).

4.6.6.

Speed Measuring Unit

4.6.7.

Speed Update Period

Please refer to 6.5.2 Speed Update Period"

4.6.8.

Speed Filter Depth
