Speed Sensor 1
The frequency inverters are to be adapted to the application depending on the re-
quirements. A part
of the available
Configuration

demand continuous measure-
ment of the actual speed for the control functions and methods. The necessary con-
nection of an incremental speed sensor is done on the digital control terminals S5IND
(track A) and S4IND (track B) of the frequency inverter.
Note:
With extension modules EM and sensor input modules, it is also possi-
ble to connect and evaluate sensors as speed sensor 2. Please refer to
the corresponding operating instructions. Speed sensor 1 and speed
sensor 2 are configured independently from one another.

for speed sensor 1 can be selected according to the connected
incremental speed sensor. Connect an unipolar speed sensor to the standard control
terminals.

1
–
Single evaluation
Two-channel speed sensor with recognition of direction
of rotation via track signals A and B; one signal edge is
evaluated per division mark.
4
–
Quadruple evalua-
tion
Two-channel speed sensor with recognition of direction
of rotation via track signals A and B; four signal edges
are evaluated per division mark.
11
–
Single evaluation
without sign
One-channel speed sensor via track signal A; the actual
speed value is positive. One signal edge is evaluated per
division mark. The digital input S4IND is available for
further functions.
12
–
Double evaluation
without sign
One-channel speed sensor via track signal A; the actual
speed value is positive. Two signal edges are evaluated
per division mark. The digital input S4IND is available
for further functions.
31
–
Single evaluation,
sense of rot. via
contact
One-channel speed sensor via track signal A. The actual
speed value is positive for signal “Low” and negative for
signal “High” at digital input S4IND. One signal edge is
evaluated per division mark.
32
–
Double evaluation,
sense of rot. via
contact
One-channel speed sensor via track signal A. The actual
speed value is positive for signal “Low” and negative for
signal “High” at digital input S4IND. Two signal edges
are evaluated per division mark.
