p0438[1]
Squarewave encoder filter time (Factory setting: 0.64 [μs])
0
No filtering
p0439[1]
Encoder ramp-up time (Factory setting: 0 [ms])
p0446[1]
Encoder SSI number of bits before the absolute value (Factory setting: 0)
p0447[1]
Encoder SSI number of bits absolute value
(Factory setting: 25)
p0448[1]
Encoder SSI number of bits after the absolute value (Factory setting: 0)
p0449[1]
Encoder SSI number of bits, filler bits
(Factory setting: 1)
Sets the number of filler bits for double absolute value transfer in the SSI protocol.
This parameter is only of significance for p0429.2 = 1.
r0452[1]
Squarewave encoder filter time display
p0453[1]
Pulse encoder evaluation zero speed measuring time
(Factory setting: 1000 [ms])
If no pulses are detected from track A/B during this time, a speed actual value of zero is output.
This function is required for slow-running motors so that actual speeds close to zero can be output correctly.
