03/12 EM-ABS-01 for ACU 93
8.3 Digital inputs EM-SxIND
The EM-ABS-01 extension module has three digital inputs. The assignment of the con-
trol si
nals to the available software functions can be adapted to the application in
question. Depending on the
Configuration 30 selected, the default assi
nment or the
selection of the operation mode differ. In addition to the available digital control in-
puts, further internal logic signals are available as sources.
The individual software functions are assigned to the various signal sources via para-
meterizable inputs. This enables a flexible use of the digital control signals.
Operation mode Function
320 - EM-S1IND Signal on digital input 1 (X410B.2)
321 - EM-S2IND Signal on digital input 2 (X410B.3)
322 - EM-S3IND Signal on digital input 3 (X410B.4)
520 - EM-S1IND inverted Inverted signal on digital input 1 (X410B.2)
521 - EM-S2IND inverted Inverted signal on digital input 2 (X410B.3)
522 - EM-S3IND inverted Inverted signal on digital input 3 (X410B.4)
lon
side the operation modes listed, those stated in the operatin
instructions of the
frequency inverter in the chapter "Digital inputs" also apply.
8.3.1 Fixed reference value and fixed value change-over
Depending on the
Reference Frequency Source 475 selected, fixed frequencies can be
used as reference values. The module extends the functionality described in the fre-
quency inverter user manual (Parameters
Fixed frequency change-over 1 66 and
ixed frequency change-over 2 67) by parameter Fixed frequency change-over 3 131
and the corresponding parameters Fixed frequency 5 485, Fixed frequency 6 486,
ixed frequency 7 487, Fixed frequency 8 488.
