Parameters
List of parameters
p0436[0...n] Encoder SSI parity bit / Enc SSI parity bit
CU250D-2_DP_F Access level: 3
CU250D-2_PN_F
Can be changed: C(4)
Units group: -
Min
0
Description: Sets the position and parity of the parity bit in the SSI protocol.
Notice: The bit may only be positioned before (p0446) or after (p0448) the absolute value in the SSI protocol.
Note: Value = dcba
ba: Position of the parity bit in the protocol (0 ... 63).
c: Parity (0: even, 1: uneven).
d: State of the evaluation (0: Off, 1: On).
Example:
p0436 = 1015
--> The evaluation is switched in and the parity bit is at position 15 with even parity.
p0436 = 1115
--> The evaluation is switched in and the parity bit is at position 15 with uneven parity.
p0437[0...n] Sensor Module configuration extended / SM config ext
Access level: 3
Can be changed: C(4)
Units group: -
Min
-
Description: Sets the extended configuration of the Sensor Module.
Bit field: Bit Signal name
00 Data logger
01 Zero mark edge detection
02 Correction position actual value XIST1
04 Edge evaluation bit 0
05 Edge evaluation bit 1
06 Freeze the speed actual value for dn/dt
errors
11 Fault handling after PROFIdrive
12 Activate additional messages
13 Support absolute position for incremental
encoder
26 Deselect track monitoring
Dependency: Refer to: p0430, r0459
Note: A value of zero is displayed if an encoder is not present.
Re bit 00:
When the data logger (trace) is activated, in the case of a fault, data before and after the event are recorded
(traced) and saved in files on the non-volatile memory medium. Experts can then evaluate this data.
Re bit 01:
If bit = 0, the zero mark is evaluated by ANDing tracks A and B and the zero mark.
For bit = 1, the zero mark is evaluated depending on the direction of rotation detected. For a positive direction of
rotation, the positive edge of the zero mark is considered and for a negative direction of rotation, the negative edge
of the zero mark.
Re bit 02:
If the bit is set, in the event of a deviation less than the tolerance window for the zero mark (p4681, p4682), the
pulses per revolution are corrected. If the bit is not set, encoder fault F3x131 is triggered.
