5.5.2 Internal encoder (H2/H4) signals
The internal encoder quadrature signal generates 1024 pulses (4096 counts) per revolu-
tion. To output the signals A and B on the RS422/485 A and B port, write to the following
registers via a little program in the RxP program:
Set register 223 to 5140
Set register 222 to 4160
The Multifunction interface is thereby set up as a permanent RS422 output interface.
5.5.3 Quadrature signals from the internal pulse generator
The internal pulse generator has a resolution of 409600 cpr (20 MHz at 3000 RPM), but
for the output channel it is scaled by 16 in order to limit the max output frequency to
1.28 MHz at 3000 RPM.
Set register 223 to 4626
Set register 222 to 4160
Then set the internal pulse generator to quadrature format:
Which can also be done without MacTalk:

Multifunction I/O setup
A general setup register for many settings in the motor. Only
bit 2 and 3 are used for this setting, all other bits must not be
changed. This table shows how the combo box in MacTalk is
setting the bits:
