2.2 List of parameters
Description:
Sets the filter time for a squarewave encoder.
The hardware of the squarewave encoder only supports the following values:
0: No filtering
0.04 µs
0.64 µs
2.56 µs
10.24 µs
20.48 µs
Dependency:
Refer to: r0452
Notice:
If the filter time is too long, the track signals A/B/R may be suppressed and the appropriate messages output.
Note:
The most suitable filter time depends on the number of pulses and maximum speed of the square-wave encoder.
The filter time is automatically corrected to the next value when entering a non-specified value. In this case, no
message is output.
The effective filter time is displayed in r0452.
Description:
Sets the ramp-up time for the encoder.
The encoder supplies stable track signals once this time has elapsed.
Note:
This parameter is automatically pre-set for encoders from the encoder list (p0400).
Description:
Copies the actual serial number of the encoder belonging to this Encoder Data Set (EDS) to p0441 ... p0445.
Example:
For p0440[0] = 1, the serial number of the encoder belonging EDS0 is copied to p0441[0] ... p0445[0].
Value:
0:
No action
1:
Transfer serial number
Dependency:
Refer to: p0441, p0442, p0443, p0444, p0445, r0460, r0461, r0462, r0463, r0464
Note:
For encoders with serial number, encoder replacement is monitored in order to request angular commutation
calibration (adjustment) for motor encoders and absolute calibration for direct measuring systems with absolute value
data. The serial number, which from then onwards is used for monitoring purposes, can be transferred using p0440.
In the following cases, copying is automatically started in the following cases:
1.) When commissioning 1FT6, 1FK6, 1FK7 motors.
2.) When writing into p0431.
3.) For p1990 = 1.
p0440 is automatically set to 0 when the copying has been completed.
In order to permanently accept the copied values, it is necessary to save in a non-volatile fashion (p0977).
