Siemens SINAMICS G120 List Manual page 85

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.
p0405[0...n] Square-wave encoder track A/B / Sq-wave enc A/B
Access level: 3
Can be changed: C(4)
Unit group: -
Min
-
Description: Settings for the track A/B in a square-wave encoder.
For square-wave encoders, p0404.3 must also be 1.
Bit field: Bit

05
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.
p0407[0...n] Linear encoder grid division / Enc grid div
Access level: 3
Can be changed: C(4)
Unit group: -
Min
0 [nm]
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.
p0408[0...n] Rotary encoder pulse number / Rot enc pulse No.
Access level: 3
Can be changed: C(4)
Unit group: -
Min
0
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.
