5.165 L_TbDeadband - dead band with gain
This FB produces a symmetrical dead band around zero.
• The attenuation of the input signal caused by the dead band can be compensated by a parame-
terisable gain.
• The value output to output dnOut is internally limited to ±2
31
-1.
•The bLimitActive output displays if a limitation is active.
• The function corresponds by approximation to the "DB" function of the 9300 servo inverter.

Identifier/data type Information/possible settings
dnIn
DINT
Input signal
dnDeadband
DINT
Dead band area for the input signal
• Value is internally limited to ≥0.
Identifier/data type Value/meaning
dnOut
DINT
Output signal
•If |dnIn| ≤ dnDeadband the output is set to zero.
•If |dnIn| > dnDeadband the difference multiplied by the parameterised gain is
output as output signal.
• The sign results from the sign of dnIn and the sign of the selected gain.
• Internally limited to ±2
31
-1
bLimitActive
BOOL
Output signal within the limitation
TRUE The output signal dnOut is limited.
