All explanations and hints to menu functions relate to this software.
7.1 Configuration of rotational speed
The preset of revolutions per minute of the spindle can be achieved by two ways:
Preset manually via panel keys
In menu 'Analogue Inputs' option button 0V has to be enabled in the line of duty RPM . (no analogue
input is assigned to this function)
The duty RPM is displayed on the LCD and can be changed with
UP / DOWN
(holding a key down
increases the count rate). RPM can be changed during operation
Preset via analogue input
duty RPM
In menu 'Analogue Inputs' option button 0V has to be disabled and the function duty RPM . has to
be assigned to an analogue input. Additionally a scaling has to be selected from the list box duty RPM
(e.g.: 1V/10.000RPM)
The value of the duty RPM is displayed on the LCD according to the scaling and the voltage at the
input. A voltage of 0V leads to a standstill and a voltage higher than 0V leads to a startup upto the
desired revolution. An input voltage of 4V and a scaling as above mentioned lead to a revolution of
40.000 rpm.
The settings have to be downloaded into the converter with the button write data.
CAUTION: The operation of a spindle with a wrong spindle characteristic
may cause severe damages at spindle or converter.
To avoid this, please ensure that the correct spindle
characteristic is selected!
Important: For this setup "PIN 11-12 Start" has to be inactive!
