The PLC is used to control the line contactor, because the Line Module 5/10 kW (without
DRIVE-CLiQ) does not have any internal control logic for control and monitoring. An
appropriate activation and deactivation must be observed. Also see the "Line Contactor
Control" section
Because the Smart Line Module (5/10 kW) does not have any DRIVE-CLiQ connection,
digital signals are used for the signal exchange between the Smart Line Module and the
PLC.
The "Infeed Ready" signal from the Line Module must be switched parallel on all
connected Motor Modules to enable the Motor Modules here. The signal interconnection
is made within the Drive Module in the Control Unit.
A Voltage Protection Module (VPM) is provided to protect the 1FE motor against over-
voltages. The signal contact from the VPM must be interconnected with the Control Unit.
When the VPM is triggered, an OFF2 (=3.-K11, X132: 10, DI/DO 14) of the corresponding
axis will be initiated.
Because the 1FE motor does not have any internal sensor, an SMC20 module must be
used to connect a separate external sensor (e.g. SIMAG H2) to the Motor Module.
