5 Communication and user modules
Shielding
Lust devices are connected by 9-pin connectors.
In the case of connections with D-SUB connectors, ensure that the shield
is connected via the connector housing (2). For that reason the screw
fittings (1) of the connectors must always be tightened.

5.3.2 Communication
via CAN
LUST
Two modes are available for control of the inverter modules via CAN:
1. Control of the drive unit by way of the state machine defined in
DRIVECOM profile no. 22 of January 1994 for Interbus.
2. Direct selection of the following functions of the drive unit by way of
the control word:
− Transfer of reference and actual values
− Starting and stopping the drive
− Selection of fixed frequencies and ramps
− Error resets
− User data set switchover
− Characteristic switchover
− Setting of digital outputs of the device
− Transfer of various states of the device
− Transfer of states of the digital inputs of the device
