Notice: An encoder type with p0400 < 9999 defines an encoder for which there is an encoder parameter list.
When selecting a catalog encoder (p0400 < 9999) the parameters from the encoder parameter list cannot be
changed (write protection). To remove write protection, the encoder type should be set to a third-party encoder
(p0400 = 9999).
If the encoder interface p0468[x] is reconfigured, the encoder configuration is reset p0400[x] = 0.
Note: The connected encoder can be identified by setting p0400 to 10000 or 10100. This assumes that the encoder
supports this method, which is possible in the following cases: Motor with DRIVE-CLiQ, encoder with EnDat
interface, DRIVE-CLiQ encoder, encoder with SSI interface (only 10100).
The encoder data (e.g. pulse number p0408) can only be changed when p0400 = 9999.
When using an encoder with track A/B and zero pulse, as standard, fine synchronization is not set using a zero mark.
If, for a synchronous motor, fine synchronization is to be realized using a zero mark, then the following must be
executed:
- set p0400 to 9999
- set p0404.15 to 1
Prerequisite:
Coarse synchronization must be selected (e.g. pole position identification) and the zero pulse of the encoder must be
either mechanically or electronically (p0431) adjusted to the pole position.
For p0400 = 10000 the following applies:
If an identification is not possible, then p0400 is set to 0.
For p0400 = 10100 the following applies:
If an identification is not possible, p0400 remains set to 10100 until it becomes possible.

Dependency: Refer to: p0410, p0432, p0433
Note: For p0402 = 1:
Automatic setting of p0410 = 0000 bin, p0432 = 1, p0433 = 1.
For p0402 = 2:
Automatic setting of p0410 = 0011 bin, p0432 = 7, p0433 = 2.
For p0402 = 3:
Automatic setting of p0410 = 0011 bin, p0432 = 17, p0433 = 4.
For p0402 = 4:
Automatic setting of p0410 = 0011 bin, p0432 = 10, p0433 = 2.
For p0402 = 9999:
No automatic setting of p0410, p0432, p0433. The parameters should be manually set.
For p0402 = 10000:
It is only possible to identify the gearbox type for a motor with DRIVE-CLiQ. Parameters p0410, p0432 and p0433 are
set corresponding to the identified gearbox. If an identification is not possible, then p0402 is set to 9999.
