Unipolar spindle or unipolar motor

Introduction
The drive can be moved in two directions. Selecting the "Unipolar spindle" option switches
the voltage range of the analog output voltage.
Unipolar spindle not selected
If the "Unipolar spindle" option is not selected, an analog voltage in the range of -10 V to
+10 V is output as the setpoint.
Unipolar spindle selected
If the "Unipolar spindle" check box is selected, an analog voltage in the range of 0 V to +10
V is output as the setpoint. The direction of rotation is then output from the ADI4, depending
on the current speed setpoint, via a digital output of the ADI4:
● Direction of rotation signal for Axis 1 → Digital output X6-1, Pin 6
● Direction of rotation signal for Axis 2 → Digital output X6-1, Pin 7
● Direction of rotation signal for Axis 3 → Digital output X6-1, Pin 8
● Direction of rotation signal for Axis 4 → Digital output X6-1, Pin 9
Note
"Unipolar spindle" (or "Unipolar motor") function is not available.
