Functional Description 4
Motor with SC speed controller 4.3
FG (core 6)
Digital output.
The digital output is a switch which switches to GND (open collector with integrated pull-up
resistance of 22 k

).
Output voltage: max. U
P
.
Output current: max. 15 mA.
The digital output can be configured for different tasks:
Error output
Output switches to high level if current limiting is activated. The delay between activation of „
current limiting and activation of the output can be adjusted.
Output switches to low level if current limiting is deactivated.
„
Frequency output
Frequency output for reading out the actual motor speed.
Signal setup: 6 pulses per motor revolution.
1 revolution
NOTE Pull-up resistance
An additional, external pull-up resistance can be connected to increase the edge steepness. The ma-
ximum loadability of the digital output must be noted and observed. See circuit diagram:

Due to the coupling of the internal pull-up resistance
between FG and the supply voltage U
P
, conducted elec-
tromagnetic RF interference, which affects the supply vol-
tage, can drastically worsen the frequency signal.
If operated properly and as intended, the speed and
direct of rotation of the motor are not impaired by this
interference.
