Description
The Smart Line Module is a non-regulated infeed/energy recovery unit. The Smart Line Module
supplies the Motor Modules with a non-regulated DC voltage at the DC link busbars. In infeed
mode, the Smart Line Module exhibits the typical current and voltage waveforms of a 6-pulse
diode rectifier bridge.
Smart Line Modules are suitable for direct operation on TN, TT and IT systems.
In the energy recovery mode, the current waveform is square waved.
16 kW and 24 kW Smart Line Modules are equipped with a DRIVE-CLiQ connection, which means
that when required, you can deactivate energy recovery using parameter p3533.
The DC link starts precharging as soon as the line voltage is applied and is independent of its
phase sequence direction. Load can be applied to the DC link after the Smart Line Module has
been enabled.
A main contactor can be installed on the line side if the system has to be electrically isolated from
the line supply.
Note
Operation on line supplies where energy recovery is not possible
For line supply systems without energy recovery capability (e.g. a diesel generator), device
faults can occur as the braking energy cannot be dissipated.
• Deactivate the energy recovery function of the Smart Line Modules using parameter p3533.
• The braking energy must then be dissipated via an additional Braking Module with braking
resistor in the drive lineup.
