5.166 L_TbDeadband_n - scaled 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 dnOut is internally limited to ±200 %.
• The bLimitActive output displays if a limitation is active.
• The function corresponds by approximation to the "DB" function of the 9300 servo inverter.

dnOut_n
DINT
Output signal
• If |dnIn_n| ≤ C04060 the output is set to zero.
• If |dnIn_n| > C04060 the difference multiplied by the parameterised gain is out-
put as output signal.
• The sign results from the sign of dnIn_n and the sign of the selected gain.
• Internally limited to ±200 %
bLimitActive
BOOL
Output signal within the limitation
TRUE The output signal dnOut_n is limited.
