5.8 Status of the digital signals

The status of the digital signals can be read in decimal coding via the parameters

Digi-

tal inputs

250 and Digital outputs 254. The display of the di

ital input si

nals enables

checking the various control signals and their connections with the software functions

in question, in particular in commissioning.

After conversion of the decimal fi

ure into the binary system, bits 8, 9 and 10 displa

the states of the inputs EM-S1IND, EM-S2IND and EM-S3IND.

The following status of the digital input signals of the EM-IO-02 expansion module has

been displayed

− Digital input EM-S1IND = 1 – control signal 8

− Digital input EM-S2IND = 0 – control signal 9

− Digital input EM-S3IND = 1 – control signal 10

Note: The three digital inputs of the EM-IO-02 expansion module can be used

for the evaluation of a speed sensor via the parameter

Operation mode

Speed sensor 2

493. The control si

nals are set to the lo

ical value zero

as a function of the selected operation mode.
