Drive group with line contactor, Smart Line Module without DRIVE-CLiQ connection, without safety
functions, motor protection without Voltage Protection Module (VPM).
● Power supply of the NCU 710 (=3.-K11)
● Control signals to the NCU; digital inputs and digital outputs in accordance with standard
● DRIVE-CLiQ connection to the Motor Module
● PROFIBUS connection to the distributed peripherals
● Supply and control of the Smart Line Module (=3.-Q51), including the integration of the
● Supply and control of the Single Motor Module
● Connection of the motor, holding brake and sensor system to the Motor Module (=3.-Q61)
● Connection of the motor and separate sensor system (=3.-B78) to the Motor Module (=3.-
● Motor protection (=3.-F75) by the Voltage Protection Module (VPM)
The drive group consists of the Control Unit (=3.-K11), the Smart Line Module (=3.-Q51), two
Motor Modules (=3.-Q61, =3.-Q71), the Voltage Protection Module (=3.-F75) and the SIMAG
H2 (=3.B78) actual value sensor. The DRIVE-CLiQ connection is used for the
communication between the Control Unit and the Motor Modules.
Functions
● Signal exchange
● Interlocking of external status and fault signals
● Interlocking of component states and system signals
● Enable signal from the Smart Line Module (5/10 kW)

The signal exchange between the NCU 710 Control Unit and the PLC
External fault signals, such as the monitoring of the safety cut-outs (=1.-F62, =1.-F63,
=1.-F64), circuit-breakers (=1.-Q36, =1.-Q41), etc., may also need to be interlocked with
the On/Off command. Signals can be visualized appropriately on the Operator Panel.
Depending on their information and importance, some internal status signals can or must
be linked with the On/Off command, controller enable, etc.
The protective circuit of the Enable Pulses digital input (X21: 3/ 4) is required for the
Smart Line Module (=3.-Q51). Before the main power switch is used to switch off the
drive group, the Enable Pulses input on the Smart Line Module must be disabled, for
example, using a leading (<=10 ms) auxiliary switch on the main power switch. The
"Infeed Ready" signal is activated only when the Smart Line Module is operating correctly
and the DC link has started properly.
