6.18.7 Analog spindle with unipolar motor
The same polarity of the nominal voltage value is output for both directions of
rotation (M3 and M4) for "unipolar" spindles. (For example, for a speed of 9 V,
or 1000 rpm, a voltage of +4.5 V is output for S500 for both M3 and M4.) The
motor is then switched over by means of a contactor controlled by a PLC
output.
You configure a unipolar spindle as follows:
Open the parameter set of the spindle concerned and move the cursor to
the CfgAxisAnalog config object.
Add the optional parameter MP_unipolar (400113) to the configuration.
Configure the parameter according to your needs (see the parameter
description below)

A positive voltage is output for each direction of rotation (M3,
M4).
always negative
A negative voltage is output for each direction of rotation (M3,
M4).
