Function modules
Communication with AS-Interface Double Slave GLK31A
9.2 Function modules
The drive-specific function assignment of the cyclic data bits is carried out in the
MOVIMOT
®
inverter. This chapter describes this function assignment.
The AS-Interface parameter bits P2 – P0 are used for switching between the drive
functions. These parameters determine the meaning of the data bits. It is possible to
change between function modules during ongoing operation and with enabled
MOVIGEAR
®
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 MOVIGEAR
®
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
transmitted from the slave to the master according to the MOVIGEAR
®
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
MOVIGEAR
®
drive changes to "Stop".
There is no feedback in this case. This is why all the input data in the MOVIGEAR
®
status word is set to "0" (not ready).
