To avoid possible resonance in the drive system, it is possible to program three jump frequency
ranges using functions A063...A068.
The jump frequency defines the frequency at which the drive should not be operated in steady-state.
The adjustable jump frequency range determines the frequency range faded out and actions
symmetrical to the jump frequency.
General
The PID controller is designed as a process controller with the variable “Frequency [Hz]”, whereby
P (kp), I (T
N) and D (Tv) can be adjusted individually. The reverence and actual value are standardi-
sed in % (range 0...100 %). For better presentation, they can be converted to the individual plant
value using A075 (e.g. flow 0...30 l/h).
The PID controller output is limited with 0 Hz (or A062) at the bottom and with the maximum
frequency A004 (or A061) at the top end. As a result, there is no reversal of the motor in the event
of negative deviation.
In order to optimize the disturbance behaviour of the controller, it is advisable to set the acceleration
and deceleration ramps as small as possible.
