7.6 Adjustment of Rotational Speed
The preset of the rotational speed can be achieved by two ways:
✓
manually preset with menu keys
For this, the Option-Button 0 in the line Duty speed in the grey field in the menu " Analogue-Inputs "
of SFU Terminal Software has to be activated. By this all analogue inputs were switched to inactive and
no analogue signal is selected for Start.
The set value for rotational speed is displayed at the LCD-Display and can be adjusted with the rotary
encoder. The speed of change is dependent on the speed of dialing. The rotational speed can altered
during operation, also.
✓
preselection with a voltage applied to the analogue input SetValue Rotational speed
For this, an analogue input has to be assigned to this function, which can be done in SFU Terminal
Software in the menu "
Analogue-Inputs ". Additionally it has to be selected a scaling for the analogue
voltage in the listbox field at left. 3 scalings are possible: 1V/10.000rpm or 1V/1.000rpm or 0-10V
min/max).
The value of the rotational speed according the scaling is displayed on the LCD-display and can be
altered as wanted.
An input voltage of 0V leads to Standstill and a voltage > min voltage will make the spindle start up to
the speed according to the current scaling.
A scaling 1V/10.000 and a voltage of 4V will cause a speed of 40.000 rpm.
All settings made in SFU-Terminal have to downloaded into the SFU before they are valid with the
button Write only I/O (F6) .
