12.6.8 Parameterising digital input filters
Counting pulses at the inputs E.0 and E.1 must have a specific minimum length to
be evaluated. The pulse length T
Pulse
is set via digital input filters.
l Lenze setting: T
Pulse
= 2.5 ms
l Filter factor A is defined via byte 1 of the parameter data:
– Permissible values: 0 ... 255 (Lenze setting: 0)
l Filter factor B is defined via byte 2 of the parameter data:
– Permissible values: 0 ... 255 (Lenze setting: 0)
T
Pulse
³ (Filter factor A + 1) × (Filter factor B + 1) × 2.5 ms
Filter factor settings:
l Filter factor A = 3
l Filter factor B = 0
Counting pulses with the following minimum length are evaluated:
T
Pulse
³ (3 + 1) × (0 + 1) × 2.5 ms
T
Pulse
³ 10 ms
