Impulse Inputs
The input impulses must be applied to the 9-position Sub-D-connector marked “Input”
(male connector on unit site). The pin assignment is shown in the block diagram and is also
printed to the top side of the unit.
The 6-position DIL switch on top of the unit provides setting of the desired input characteristics.
With most of all practical applications one of the following two configurations will be suitable:
Switch Setting

Other switch positions than shown above are reserved for special applications and must only
be used upon advice of motrona.
*)
Where for encoder supply a voltage higher than 5.4 volts should be required, please apply an
appropriate voltage to teVext.

Where for encoder supply a voltage higher than +V
B
should be required, please apply an
appropriate voltage to teVext.
