Shielding
The use of shielded cables is normally not demanded but offers high protection against electro-
magnetic interferences, especially high frequencies. However, the effectiveness of the shield depends
on careful installation of the line.
If shielded cables are used, the shield should be placed at
“ PE ” on at least one side (preferably on the
master connection). The occurrence of compensating currents may have to be considered if the shield
is contacted on both sides.

5.14 Open-Collector output “ A1 ” (status / tacho)
Open-Collector pulse output for status display or speed display.
Status display (function for factory setting)
Depending on the operating state of the device, the output “ A1 ” is switched to
GND potential for a certain number of pulses.
The status of the device can be displayed by this digitally coded signal.
With the output voltage
“ +10 V ” a standard LED / low-power LED can be
controlled by using a pull-up resistor.
This lights when the output
“ A1 Status Out OC ” (OC = Open-Collector) is on GND
potential.
The details of which pull-up resistor needs to be used depend on the speci
fi cation
on the LED that is used.

Tacho out
Alternatively, via output “ A1 ” , the current motor speed can be output.
The frequency (duty cycle 50 : 50) that can be measured by a pull-up resistor at
the output
“ A1 ” corresponds to the motor speed.
