    8 handling 8.1 manual control Each channel can be controlled by turning the encoder knob on the front panel. Turning clockwise increases the applied voltage signal, turning counter clockwise reduces the applied voltage signal. Depend on how fast the knob is turned, the change of the applied signal can be adjusted.

  • Page 16: Controlling Via Interface

    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.
