Squarewave Encoder Filter Time / Enc T_Filt; Encoder Ramp-Up Time / Enc Ramp-Up Time; Copy Encoder Serial Number / Copy Enc Ser_No - Siemens SINAMICS G150 Manual

2 Parameters
2.2 List of parameters
Re bit 29:
When the bit is set, the EnDat encoder is initialized under a certain velocity and, therefore, with high accuracy. If
initialization at a higher velocity is requested, fault F31151, F32151, or F33151 is output.
Re bit 31:
When monitoring is active, the levels of the individual track signals and the corresponding inverted track signals are
monitored separately.

Squarewave encoder filter time / Enc t_filt

ENC, VECTOR_G Can be changed: C2(4)
Data type: FloatingPoint32
P-Group: Encoder
Not for motor type: -
Min
0.00 [µs]
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.
p0439[0...n]

Encoder ramp-up time / Enc ramp-up time

ENC, VECTOR_G Can be changed: C2(4)
Data type: Unsigned16
P-Group: Encoder
Not for motor type: -
Min
0 [ms]
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).
p0440[0...n]

Copy encoder serial number / Copy enc ser_no

ENC, VECTOR_G Can be changed: C2(4)
Data type: Integer16
P-Group: Encoder
Not for motor type: -
Min
0
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].
