13. handling
The actuator is connected to the
“PIEZO” plug. The “ANALOG” plug offers an analog interface to
control the amplifier using a voltage between 0 and +10 V. Please remove any analog input
voltage from the amplifier before you turn the system on or off to avoid damage
(
modon,channal,0
).
After switching on, the red status LED displays the initialization sequence of the function groups for
the device. During this time all amplifiers transfer their stored specific values (DSP parameter) and
the specific actuator values (read out from the ID chip of the connected actuator) to the main
controller. The amplifier channels without a connected actuator will continue to blink.
The actuator is below the control range on the negative point of the whole travel range (position on
the left, see image 3). Pressing the OL/CL button the device is now in closed loop mode, the
actuator moves on the zero position of the control range (position „0µm“). The actuator can
execute jumps depending on independent the adjusted position. If the max closed loop position is
adjusted per set-command, then the max controlled travel range (
position “max) is reached. The
travel range depends on the specifications of the actuator and can vary according to the actuator
type.

The blinking OL/CL-LED shows an overload or underload. Please try to avoid this. When an
external analog voltage is applied, try to decrease or remove it. If the LEDs is still blinking, check
the connection between the amplifier and actuator. Additionally, a mechanical blocking or overload
of the actuator can prevent actuators from reaching their position. If none of the described
troubleshooting has worked, turn off the system and contact our support team. Please do not
