Parameters
List of parameters
p4681[0...n] Zero mark monitoring tolerance window limit 1 positive / ZM tol lim 1 pos
Access level: 3
Can be changed: C(4)
Units group: -
Min
0
Description: Sets the positive tolerance window in encoder pulses for limit 1 for the zero mark monitoring.
If the deviation is less than this limit, then the pulse number is not corrected. If it is higher than this limit, fault
F3x131 is triggered.
If fault F3x131 is re-parameterized to alarm (A) or no message (N), the encoder pulses which have not been cor-
rected are added to the accumulator (p4688). The accumulator can be de-activated using p0437.7.
Dependency: Refer to: p0437, p4688
Refer to: F31131
Note: This monitoring is activated by setting p0437.2 = 1 (position actual value correction).
The positive limit describes additional pulses due to EMC.
p4682[0...n] Zero mark monitoring tolerance window limit 1 negative / ZM tol lim 1 neg
Access level: 3
Can be changed: C(4)
Units group: -
Min
-1001
Description: Sets the negative tolerance window in encoder pulses for limit 1 for the zero mark monitoring.
If the deviation is less than this limit, the PPR is not corrected. If it is higher than this limit, fault F3x131 is triggered.
If fault F3x131 is re-parameterized to alarm (A) or no message (N), the encoder pulses which have not been cor-
rected are added to the accumulator (p4688). The accumulator can be de-activated using p0437.7.
Dependency: Refer to: p0437, p4681, p4688
Refer to: F31131
Note: This monitoring is activated by setting p0437.2 = 1 (position actual value correction).
For a set value = -1001, the negated value of p4681 is effective.
The negative limit describes the pulses lost due to a covered glass panel in the incremental encoder.
p4683[0...n] Zero mark monitoring tolerance window alarm threshold positive / ZM tol A_thr pos
Access level: 3
Can be changed: C(4)
Units group: -
Min
0
Description: Sets the positive tolerance window in encoder pulses for limit 2 for the zero mark monitoring.
If the zero mark deviation is higher than the tolerance set in p4681 and p4682 and fault F3x131 is re-parameterized
to alarm (A) or no message (N), the accumulator p4688 is compared with this parameter and, if applicable, alarm
A3x422 is output for 5 seconds.
Dependency: Refer to: p0437, p4681, p4682, p4688
Refer to: F31131, A31422
Note: Zero mark monitoring is activated by setting p0437.2 = 1 (position actual value correction).
