Unit Structure
3.4.2 AS-Interface option
The AS-Interface option is located on the connection board in the connection box.
DRC-DAC is available with the following AS-Interface variants:
• GLK30A binary slave
• GLK31A double slave for drive with several speed setpoints and ramps
GLK30A binary
slave Connected to the AS-Interface, the GLK30A slave works like a module with 4 inputs and
4 outputs.
The cyclic output bits control the DRC-DAC inverter.
The input bits transmit the status of the drive and two additional sensor signals to the
AS-Interface master.
The acyclic parameter bits are used to select speed scaling factors.
GLK31A double
slave The GLK31A option works as a double slave on the AS-Interface according to AS-
Interface specification 3.0.
Serial AS-Interface data transmission (analog profile) allows for writing and reading
DRC-DAC parameters and display values.
The DRC-DAC inverter is controlled via the cyclic output bits. The coding of the data bits
is specified in different function modules. The DRC-DAC inverter interprets these bits as
different control and status codes. You can switch between the function modules using
the acyclic parameter bits.
The input bits transmit the status of the drive and 2 additional sensor signals to the AS-
Interface master.
