Parameters
List of parameters
p0404[0...n] Encoder configuration effective / Enc_config eff
CU250D-2_DP_F Access level: 3
CU250D-2_PN_F
Can be changed: C(4)
Units group: -
Min
-
Description: Settings for the basic encoder properties.
Bit field: Bit Signal name
00 Linear encoder
01 Absolute encoder
02 Multiturn encoder
03 Track A/B sq-wave
09 SSI encoder
12 Equidistant zero mark
13 Irregular zero mark
14 Distance-coded zero mark
21 Voltage level 24 V
Caution: 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
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 calcu-
lated.
p0405[0...n] Square-wave encoder track A/B / Sq-wave enc A/B
Access level: 3
Can be changed: C(4)
Units 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 Signal name
00 Signal
01 Level
02 Track monitoring
03 Zero pulse
04 Switching threshold
Caution: 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: Re bit 00:
For G120D, only "Bipolar" is supported.
