Function modules
The drive-specific functions of the cyclic data bits are assigned in the DRC inverter. This
chapter describes this function assignment.
The AS-Interface parameter bits P2 – P0 are used for switching between the drive
functions. They determine the meaning of the data bits. Switching between the function
modules is also possible during operation and with enabled DRC inverter. The meaning
of the data bits might change in this case.
9.2.1
Description of parameter bits
The following table shows the function assignment of the data bits to the selected
function module (AS-Interface parameter bits).
• When function modules 2
hex
– 7
hex
are selected, data bits DI0 and DI1 are transmit-
ted from the slave to the master according to the DRC status word. Data bits DI2 and
DI3 contain the state of sensor inputs DI2 and DI3.
• When function modules 0
hex
– 1
hex
are selected, all 4 data bits DI0 – DI3 are trans-
mitted from the slave to the master according to the DRC status word. The state of
the sensor inputs is not transmitted.

INFORMATION
If the AS-Interface master selects the parameter bits with a reserved function, the DRC
drive changes to "Stop".
There is no feedback in this case. This is why all the input data in the DRC status word
is set to "0" (not ready).
