on the system the soft start function is started for 10 seconds to initiate the actuator. While
this routine the actuator is moved once through the whole motion range and back. During
soft start the modulation input and the encoder are disabled. After soft start the amplifier is
working normally. Command without value reads out the current value.
command 'light'
call: light,<0...255>
example: light,0
answer: none
switch off the display
The command „light“ can be used to control the brightness of the display. Adjustable values
are between “0” (display off) and “255” maximum brightness. The last adjustment will be
stored and will be automatically used if the amplifier will be switched on. Command without
value reads out the current value.
Please pay attention!
If the display remains dark after switching on the amplifier the display
may have been adjusted to “light,0” before. Please read out the value by input command
“light” and change the value if necessary.

This example shows the sequence of the commands to move the actuator on channel 0 with
the NV40/3CLE from the minimal position 0 µm to 10µm, channel 1 is set in open loop to
90Volts and channel 2 is set to closed loop to position 20.5µm:
