Input for armature voltage control using
IxR compensation (motor terminal B), see 7.3.1
For tacho operation with UTN > 45V terminal ~ instead of
terminal ~J can be used in order to obtain a better
resolution of the ~ triminer. C 101 rnust be removed in
this oase.
GND, controller reference point
Input for actual speed value with nominal tacho voltages
from 10 to 180V. For hiqh nominal tacho voltages (= 60V)
the setting sensitivity of the trimmer, which is
used as an attenuator, can be r&3uced by soldering a
series resistor R 101 instead of the nornlally used wire
bridge. C 101 must be removed in this oase.
The resistance of R 102 can be determined according
to the following equation:
