Figure 107: ASi data bus
The ASi data bus is a system solution that makes it possible to network
various assemblies. AS-Interface networks are quick and easy to set up.
The ASi LED displays of motor control unit RASP5 indicate the operating
states and allow a quick diagnosis.

The START signal or enable for the requested operating direction is issued
through DQ0 (FWD) or DQ1 (REV). Through outputs DQ2 and DQ3 fixed
frequencies FF1 to FF3 (digital setpoint value memory) are called up in binary
code. If DQ2 and DQ3 are not activated, frequency value f
potentiometer n
is output (analog setpoint memory, 0 to 50 Hz).
