PID output frequency at 100% (cn.14)
This block converts the proportional controller output value to frequency. The adjustment of cn.14 determines,
which frequency is output at 100% controller output value. A frequency of -400.0...400.0 Hz can be adjusted
(dependent on ud.02). The output value forms the output frequency (ru.03) at cS.00 Bit 0… 1 = 1 added with
the ramp output frequency (ru.02).
7.15.10.2 PID setpoint
This block describes the PID controller setpoint. The PID setpoint consists of the absolute reference (cn.01)
and an additional reference source adjustable with cn.00. The two values are added and form the PID controller
setpoint.
