2.2 List of parameters
p0429[0...n] Encoder SSI configuration / Enc SSI config
CU250D-2_PN_F Access level: 3
CU250D-2_DP_F
Can be changed: C(4)
Unit group: -
Min
-
Description: Sets the configuration for an SSI encoder.
Bit field: Bit
00
02
06
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 06:
The quiescent signal level of the data line corresponds to the inverted, set level.
p0430[0...n] Sensor Module configuration / SM config
Access level: 3
Can be changed: C(4)
Unit group: -
Min
-
Description: Sets the configuration of the Sensor Module.
Bit field: Bit
20
21
25
27
Notice: A bit-wise configuration is only possible if the corresponding property is also present in r0458.
Note: For bit 20 (speed calculation mode):
- if bit = 1, the speed is calculated via incremental difference without extrapolation.
- if bit = 0, the speed is calculated via edge time measurement with extrapolation. p0453 is effective in this mode.
For bit 21 (zero mark tolerance):
- if bit = 1, a one-off zero mark distance error is tolerated. In the event of a defect, the fault F3x100/F3x101 does not
appear, but alarm A3x400/A3x401 does.
For bit 25 (disconnect the encoder power supply on parking):
- if bit = 1, the encoder power supply is switched off on parking (0 V).
- if bit = 0, the encoder power supply is not switched off on parking, it is reduced from 24 V to 5 V.
For bit 27 (extrapolate position values):
- if bit = 1, the extrapolation of the position values is activated.
p0432[0...n] Gearbox factor encoder revolutions / Grbx_fact enc_rev
Access level: 3
Can be changed: C(4)
Unit group: -
Min
1
Description: Sets the encoder revolutions for the gearbox factor of the encoder evaluation.
The gearbox factor specifies the ratio between the encoder shaft and motor shaft (for motor encoders) or between
the encoder shaft and the load.
