9. Potentiometers
With the potentiometers it is possible to adjust the following parameters.
** Special device with designation suffix SO2 or SO3
Note! If braking times exceeding 20s are adjusted, the permissable maximum
rated device current decreases. The rated device current on the label of the
unit is than no more reached.
„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.
Caution!
If braking times exceeding 20s are adjusted, the rated device current decreases
according to the diagram on page 9. the rated device current indicated on the rating
plate is then not reached any more.
„t“ Adapting the braking time.
The braking time can be adjusted within a range of 0 - 30 (0 - 60s in the case of SO2
and SO3**). With this potentiometer, it is possible to determine the length of time for
which the braking current is to flow. During commissioning, it should be taken into
account that the braking current is switched off only approx. 2s after the motor has
come to a standstill. The adjustment is linear.
