2.2 List of parameters
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.
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 02:
When the function is activated, track monitoring can be deactivated by setting p0437.26.
For bit 05:
When the function is activated, a frequency setpoint and a direction for traveling can be entered via an encoder
interface.
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.
Description:
Sets the number of pulses for a rotary 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 number of pole pairs for a resolver is entered here.
The smallest permissible value is 1 pulse.
