2.2 List of parameters
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: ZM: Zero mark
For bit 12 (equidistant zero mark):
The zero marks occur at regular intervals (e.g. rotary encoder with 1 zero mark per revolution or linear encoder with
constant zero mark distance).
The bit activates monitoring of the zero mark distance (p0424/p0425, linear/rotary) or in the case of the linear
encoder with 1 zero mark and p0424 = 0 zero mark monitoring is activated.
For bit 13 (irregular zero mark):
The zero marks occur at irregular intervals (e.g. a linear scale with only 1 zero mark in the traversing range). The zero
mark distance is not monitored.
For bit 14 (distance-coded zero mark):
The distance (clearance) between two or several consecutive zero marks allows the absolute position to be
calculated.
Description: Settings for the track A/B in a square-wave encoder.
For square-wave encoders, p0404.3 must also be 1.
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: For bit 00:
For G120D, only "Bipolar" is supported.
For bit 01:
For G120D, only "HTL" is supported.
For bit 02:
When the function is activated, track monitoring can be de-activated by setting p0437.26.
For bit 03:
For G120D, only "Same as track A/B" is supported.
For bit 04:
For G120D, only "Low" is supported.
Description: Sets the grid division for a linear 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 lowest permissible value is 250 nm.
