Monitor Nv40/3, Nv120/1; Controlling Via Interface - piezosystemjena NV40/3 Bedienungsanleitung

Based on this a signal of 0V is related to an applied voltage of –20V and +10V is related to
+130V. In closed loop the minimum and maximum values never reaches caused by the
closed loop control reserve.
monwpa,x,1: Output of a voltage proportional to the actuator position (delivery status).
Shown in diagram 2.
The monitor output provides a voltage signal which correspondents directly to the position of
the piezo actuating system (delivery status). The value of the monitor output voltage range is
from 0V to +10V in closed loop mode and from –13V to +13V in open loop mode (minimum
and maximum depends of motion range).
monwpa,x,2: In open loop the monitor provides a voltage signal of 0V up to +10V which
corresponds to the voltage signal applied to the piezo actuator. The monitor output follows
the characteristic curve shown in diagram 1.
In closed loop the monitor output provides a voltage signal which corresponds directly to the
position of the piezo actuating system. Shown in digram 2.
For amplifiers with "closed loop" operation ("CLE" version) in combination with open loop
actuating systems, the monitor output shows a voltage signal proportional to the applied
piezo actuator control signal. The command "monwpa" is deactivated.

8.2.3 monitor NV40/3, NV120/1

The monitor output of the NV40/3, NV120/1 always provides a signal of 0V up to +10V which
directly corresponds to the voltage signal applied to the piezo actuator. The command
„monwpa" is deactivated.

8.3 controlling via interface

The amplifier series NV 40/3 and NV 120/1 can be controlled via RS232 interface. Therefore
signal parameters and information about the actuator position or status can be adjusted or
settled directly. Furthermore, the system settings of the amplifier unit can be changed by
using the interface. A fully PC controlled piezo system for automation purposes is feasible.
Please connect the amplifier system by using the RS232 or the USB interface with your PC.
During this the piezo amplifier must be switched off!
