Dependency: Refer to: p0437, p4683, p4688
Refer to: F31131, A31422
Note: Zero mark monitoring is activated by setting p0437.2 = 1 (position actual value correction).
For a set value = -100001, the negated value of p4683 is effective.
p4685[0...n] Speed actual value mean value generation / n_act mean val
Access level: 3
Can be changed: C(4)
Unit group: -
Min
0
Description: Sets the number of current controller clock cycles for mean value generation of the speed actual value.
Note: Value = 0, 1: No mean value generation.
Higher values also mean higher dead times for the speed actual value.
p4686[0...n] Zero mark minimum length / ZM min length
Access level: 3
Can be changed: C(4)
Unit group: -
Min
0
Description: Sets the minimum length for the zero mark in 1/4 encoder pulses.
Dependency: Refer to: p0425, p0437
Note: The minimum length of the zero mark must be less than the zero mark distance (p4686 < p0425).
The parameter is activated using p0437.1 = 1 (zero mark edge detection).
p4688[0...2] CO: Zero mark monitoring differential pulse count / ZM diff_pulse qty
Access level: 3
Can be changed: T
Unit group: -
Min
-2147483648
Description: Display and connector output for the number of differential pulses for the zero mark monitoring that have
accumulated.
If fault F3x131 is re-parameterized to alarm (A) or no message (N), the encoder pulses which have not been
corrected are added to the accumulator (p4688).
Index: [0] = Encoder 1
[1] = Encoder 2
[2] = Encoder 3
Dependency: Refer to: p4681, p4682, p4683, p4684
Note: The display can only be reset to zero.
r4689[0...2] CO: Squarewave encoder diagnostics / Sq-wave enc diag
Access level: 4
Can be changed: -
Unit group: -
Min
-
Description: Displays the encoder status according to PROFIdrive for a squarewave encoder.
Index: [0] = Encoder 1
[1] = Encoder 2
[2] = Encoder 3
Dependency: Refer to: A31422
Note: After alarm A3x422 is output, this parameter is set for 100 ms.
