p4685[0...n]

Speed actual value mean value generation / n_act mean val

DC_CTRL,
Can be changed: C2(4)
DC_CTRL_R,
Data type: Unsigned32
DC_CTRL_R_S,
P-Group: Encoder
DC_CTRL_S
Not for motor type: -
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

DC_CTRL,
Can be changed: C2(4)
DC_CTRL_R,
Data type: Unsigned32
DC_CTRL_R_S,
P-Group: Encoder
DC_CTRL_S
Not for motor type: -
Min
0
Description:
Sets the minimum length for the zero mark in 1/4 encoder pulses.
Dependency:
Refer to: p0425, p0437
Note:
The value for the minimum length of the zero mark must be set less than p0425.
The parameter is activated using p0437.1 = 1 (zero mark edge detection).

CO: Zero mark monitoring differential pulse count / ZM diff_pulse qty

DC_CTRL,
Can be changed: T
DC_CTRL_R,
Data type: Integer32
DC_CTRL_R_S,
P-Group: -
DC_CTRL_S
Not for motor type: -
Min
-2147483648
Description:
Displays 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] = -
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

DC_CTRL,
Can be changed: -
DC_CTRL_R,
Data type: Unsigned32
DC_CTRL_R_S,
P-Group: Encoder
DC_CTRL_S
Not for motor type: -
Min
-
Description:
Displays the encoder status according to PROFIdrive for a squarewave encoder.
Index:
[0] = Encoder 1
[1] = Encoder 2
[2] = -
Note:
After alarm A3x422 is output, this parameter is set for 100 ms.
