1.6.2 Device control
There are two modes for controlling the devices over CAN.
In the first control mode the key functions of the device can be activated
directly by way of a LUST-specific control word. This mode is termed
“EasyDrive control mode” in the following.
In the second control mode the drive unit is controlled by way of the
DRIVECOM state machine.
EasyDrive
In direct control mode, specific functions of the device are activated with
the individual control bits. Thus, for example, the STR (Start Clockwise)
function can be selected by setting just one control bit. It is also possible
here to transfer unused control terminals of the drive unit to the control for
other process tasks.
DRIVECOM
To control a drive unit in the second control mode over CAN, the state
machine defined in the DRIVECOM PROFILE no. 20 of January 1994 for
I
NTERBUS-S must be followed.
