Warning
Please note, the total contact resistance on terminals X3 - X8 of the
connected contacts must not exceed 50 Ohm. If the limit of the total contact
resistance is exceeded, a reliable operation of the motor relays at 90% of the
mains supply (230V or 400V depending on device model) is no longer
ensured. In this case the motor could start on 2 phases.
10. Potentiometers
With the potentiometers it is possible to adjust the following parameters.
Note!
If the potentiometer is adjusted to a position too far in clockwise or counter-
clockwise direction (e.g., end stop position), it may happen that no standstills
are detected. In this case, braking current flows until the end of the max.
braking time. The LED indicates „no standstill during the max. braking time“.

Starting contact
Connection of an „ON“-button (normally open contact)
X3, X4; X5, X6;
X7,X8
Braking contact
Connection of an „OFF“-button (normally closed
contact)
„I“
Adjusting the braking current:
The braking current can be adjusted in the range from approx. 10% - 100% of the rated
device current. The adjustment is roughly linear.
„t“
Adapting the standstill threshold and braking behavior at motor standstill.
With this potentiometer it is possible to adapt the motor standstill threshold to various
motor types and applications and to influence the behavior of the braking current at
motor standstill.
In „left stop“ (full counter-clockwise) position, the standstill detection function is most
sensitive, and the braking behavior, upon reaching the motor standstill, is most soft.
Possibly, the braking current is switched off even before the motor has come to a
standstill. The potentiometer has to be adjusted so that the braking current is switched
off approx. 1-1.5s after the motor has come to a standstill.
Factory-setting: approx. 40%.
