Note:
For a value of 0.0, the speed change monitoring is disabled.
When half of the parameter value is exceeded, an alarm is already generated and the speed limiting is limited to
this.
The parameter is only pre-assigned for vector drives when selecting p0340 = 1, 3.
Description:
Maximum permissible velocity difference between two computation cycles when evaluating square-wave encoders.
When the value is exceeded, depending on p0491, either a sensorless closed-loop velocity/force control is selected
or the drive is powered-down.
Note:
For a value of 0.0, the velocity change monitoring is disabled.
When half of the parameter value is exceeded, an alarm is already generated and the velocity change is limited to
this.
Description:
Selects the input terminal for connecting an equivalent zero mark (external encoder zero mark).
Values:
0:
No equivalent zero mark (evaluation of the encoder zero mark)

Index:
[0] = Encoder 1
[1] = Encoder 2
[2] = Encoder 3
Dependency:
Refer to: p0490
Notice:
To the terminal designation:
The first designation is valid for CU320, the second for CU310.
For CU310, CX32, NX10 and NX15, only DI/DO 9, 10, 11 can be selected as fast inputs (refer to the Equipment
Manual).
Note:
Refer to the encoder interface for PROFIdrive.
The terminal must be set as input.
For p0495 = 0 (factory setting), the encoder zero mark is evaluated as zero mark.
For p0495 > 0, the following applies:
Depending on the direction of motion, the positive or negative edge at the appropriate input is evaluated.
- increasing position actual values (r0482) --> the 0/1 edge is evaluated.
- decreasing position actual values (r0482) --> the 1/0 edge is evaluated.
Only one zero mark is supported. If function 2, 3 or 4 is selected, this results in an error message in Gn_ZSW.
The inversion of the inputs via p0490 affects the function "referencing with equivalent zero mark". This is the reason
that the edge evaluation is interchanged as a function of the direction of motion.
