Encoder Properties1:
0 … 5
1
0=
Differential impulses A, /A, B, /B (2 x 90°)
*)
1=
Single-ended HTL impulses (10 - 30 V, format A, B, 2 x 90°)
2=
Differential impulse input A, /A (count, step)
*)
Differential signal B, /B (static direction signal)
3=
Single-ended HTL impulse A (count, step)
Single-ended HTL signal B (static direction signal)
4=
Differential impulse input A, /A only *)
5
Single-ended HTL impulse input A only
F03.023
Direction1: positive or negative speed (forward / reverse)
0 … 1
0
0=
Positive speed when A leads B
1=
Positive speed when A lags B
F03.024
Sampling Time1:
0.000**) … 9.999
sec.
0.001
Internal measuring time to evaluate the frequency
F03.025
Wait Time1: Maximum time to wait for the next input pulse
When after this waiting time no further impulse appears, the
frequency result is set to zero (f = 0)
0.01 … 99.99
sec.
1.00
F03.026
Filter1: Digital filter for smoothing unstable input frequencies
(for detailed explications see 7.4)
0 - 8
0
0=
Filter OFF
(very fast response to changes in frequency)
1=
Floating average over the last 2 measuring cycles
2=
Floating average over the last 4 measuring cycles
3=
Floating average over the last 8 measuring cycles
4=
Floating average over the last 16 measuring cycles
5=
Exponential filter,
Τ
(63%)
= 2 x Sampling Time
6=
Exponential filter,
Τ
(63%)
= 4 x Sampling Time
7=
Exponential filter,
Τ
(63%)
= 8 x Sampling Time
8=
Exponential filter,
Τ
(63%) = 16 x Sampling Time
(very slow response to changes in frequency)
F03.027
Input Value1: Typical input frequency of the application (Hz) for
use as a scaling reference for the display
1 - 999 999
Hz
1000
F03.028
Display Value1: Desired display value
This numeric value appears in the display when the reference
frequency is applied to the input (as set under "Input Value")
1 - 999 999
1000
*)
this is valid for any kind of differential input signal (i.e. inverted signal),
no matter if RS422 or TTL or HTL level
