C33 Analog setting signal
C 3 3 R E F F I L T E R
Setting range: 0.00 to 5.00 seconds
Analog signals input from Terminals 12, V2 or C1 may
contain noise which renders the control unstable. This
function adjusts the time constant of the input filter to
remove the effects of noise.
A value that is set too large delays control response
although stabilizing the control. A value that is set too
small speeds up control response but renders the control
unstable.
If the optimum value is not known, adjust the setting if
the control is unstable or response is delayed.
Note:
The set value is commonly applied to Terminals 12, V2
and C1. For input of PID feedback, the PID control
feedback filter (H25) is used.
