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
SMC: Sensor Module Cabinet
If a technique to determine the commutation information/data has not been selected (e.g. track C/D, Hall sensor), and
the encoder pulse number is an integer multiple of the pole number, then the following applies:
The track A/B is adjusted to match the magnetic position of the motor.
Re bit 01, 02 (absolute encoder, multiturn encoder):
These bits can only be selected for EnDat encoders, SSI encoders or DRIVE-CLiQ encoders.
Re bit 10 (DRIVE-CLiQ encoder):
This bit is only used for the large-scale integrated DRIVE-CLiQ encoders that provide their encoder data directly in
DRIVE-CLiQ format without converting this data. This bit is not, therefore, set for first-generation DRIVE-CLiQ
encoders.
Re 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.
Re 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.
Re bit 14 (distance-coded zero mark):
The distance (clearance) between two or several consecutive zero marks allows the absolute position to be
calculated.
Re bit 15 (commutation with zero mark):
Only applicable for synchronous motors.
The function can be de-selected by priority via p0430.23.
For distance-coded zero marks, the following applies:
The phase sequence of the C/D track (if available) must be the same as the phase sequence of the encoder (A/B
track).
The phase sequence of the Hall signal (if available) must be the same as the phase sequence of the motor. Further,
the position of the Hall sensor must be mechanically adjusted to the motor EMF.
The fine synchronization is only started after two zero marks have been passed.
Description: Settings for the track A/B in a square-wave encoder.
For square-wave encoders, p0404.3 must also be 1.
