SINAMICS G120D
82 List Manual (LH14), 01/2016, A5E33842313
Note: The parameter applies for the following process data:
- Gx_XIST1
- Gx_XIST2 for reference mark or flying measurement
The fine resolution specifies the fraction between encoder pulses. Depending on the physical measurement principle,
an encoder pulse can be broken down into a different number of fractions (e.g. squarewave encoder: 2 bit =
resolution 4, sin/cos encoder: Typical 11 bit = resolution 2048).
For a squarewave encoder, with the factory setting, the least significant bits have the value zero, i.e. they do not
supply any useful information.
For especially high quality measuring systems, the fine resolution must be increased corresponding to the available
accuracy.
Description: Sets the fine resolution in bits of the absolute position actual values.
Dependency: Refer to: p0418
Note: This parameter applies to process data Gx_XIST2 when reading the absolute value.
Description: Sets the number of rotations that can be resolved for a rotary absolute encoder.
Notice: This parameter is automatically pre-set for encoders from the encoder list (p0400).
When selecting a catalog encoder, this parameter cannot be changed (write protection). Information in p0400 should
be carefully observed when removing write protection.
Description: Sets the resolution of the absolute position for a linear absolute encoder.
Notice: This parameter is automatically pre-set for encoders from the encoder list (p0400).
When selecting a catalog encoder, this parameter cannot be changed (write protection). Information in p0400 should
be carefully observed when removing write protection.
Note: The serial protocol of an absolute encoder provides the position with a certain resolution, e.g. 100 nm. This value
must be entered here.
Description: Sets the number of measuring steps per revolution for a rotary absolute encoder.
The resolution refers to the absolute position.
