The switches listed in the lines are allocated
as follows
The values listed in the columns are allocated
as follows
S1R
Switching speeds of switch 1 for
clockwise direction of rotation
P1
Hysteresis switching speed for
underspeed detection
S1L Switching speeds of switch 1 for anti-
clockwise direction of rotation
P2
Cut-in speed for underspeed
detection
S2R
Switching speeds of switch 2 for
clockwise direction of rotation
P3
Hysteresis switching speed for
overspeed detection
S2L Switching speeds of switch 2 for anti-
clockwise direction of rotation
P4
Cut-off speed for overspeed
detection
S3R
Switching speeds of switch 3 for
clockwise direction of rotation
P4 - Delay
Delay time before cut-off of the
switching point P4 [ms]
S3L
Switching speeds of switch 3 for anti-
clockwise direction of rotation
Only those lines and columns are displayed that are relevant to the respective function
selected by checking the appropriate boxes.
An input value "0" in the fields P1 … P4 deactivates the corresponding switch.
An input value "0" in the fields P1 … P2 deactivates underspeed detection
(see Chapters: 6.3.1, 6.3.2).
CAUTION!
When switching delay is activated the actual cut-off speed can be higher than the
set cut-off speed!
Observe also the information on determining switching accuracy described in the
Operating and Assembly Instructions " USC 42_Manual"!
The module is depicted in the display section as in
Fig. 6-10
Click "Write to device" to finish configuring the module.
6.3.1 Underspeed
Underspeed is detected. The respective switch closes first when speed P2 is exceeded;
the switch is opened again when the speed falls below the P1 threshold. The input col-
umns for "P1" and "P2" are depicted if underspeed detection is activated.
6.3.2 Rotation direction dependent
The switching speeds S1R … S3R apply to clockwise direction of rotation. The speeds
S1L … S3L apply to anticlockwise direction of rotation.
The input lines for S1R-S3R as well as S1L-S3L are depicted if 'rotation direction de-
pendent switching' is activated.
If no 'rotation direction dependent switching' is activated the switches S1 ... S3 are not
labelled with a direction of rotation indicator R or L; the entered switching speeds apply
independent of the direction of rotation.
PLEASE NOTE!
If 'rotation direction dependent switching and underspeed are selected, the under-
speed function must be equal for both directions of rotation. Either active or inactive.
