Mod/Mon - piezosystemjena d-Drive Bedienungsanleitung

The following sketch describes the step response of the different terms:
sketch 2: transfer function
When using a notch filter, the main resonant frequency will be damped by another order of
magnitude. While using open loop you can also switch on the notch filter to reduce stimulation of
the resonant frequency. Using the notch filter might increase noise.
The PID-specific parameters, kp, ki and kd, are stored in the actuator's ID-chip by default. These
parameters will work for most applications. Depending on your special application and load, the
mechanical response can be optimized.

8.3.2 MOD/MON

modulation input: MOD
The motion of the actuator can be remotely controlled using this input. The control signal must be
in the range of 0...+10 V. There is an internal addition of the MOD signal, the adjusted OFFSET
potentiometer, and the present digital value. To prevent external signals from influencing any
parameter, please switch off the analog modulation input when it's not used (modon, x, 0 see 8.5.3
commands). In function generator mode the modulation input is permanently switched off.
monitor output: MON
With a special command, many different signals can be shown. The voltage range of 0...+10 V is
available at this socket and can be monitored by using an oscilloscope. Pay attention to the inner
resistance of the monitor output.
