Smart Line Modules are infeed/regenerative feedback units that supply power to connected Motor Modules. Furthermore, they are capable of feeding regenerative energy back into the grid. The infeed occurs over a diode jumper, while stable, line-commutated regenerative feedback takes place via IGBTs with 100 % continuous energy regeneration. The regenerative capability of the modules can be deactivated by means of parameterization.

Smart Line Modules are designed for connection to grounded TN/TT and non-grounded IT supply systems.

The DC link is pre-charged by means of integrated pre-charging resistors.

To operate the Smart Line Module, the associated line reactor or a suitable transformer is required.

The Smart Line Modules have the following interfaces as standard:

• 1 line supply connection
• 1 connection for the 24 V DC electronics power supply
• 1 DC link connection (DCP, DCN) for supplying the connected Motor Modules
• 1 DC link connection (DCPA, DCNA) for connecting a Braking Module
• 3 DRIVE-CLiQ sockets
• 1 temperature sensor input for KTY84‑130, Pt1000, PTC or Pt100 (Pt1000 can be used from firmware V4.7 HF17 and higher)
• 1 PE/protective conductor connection (2 connections for sizes HX and JX)

The status of the Smart Line Modules is indicated via three LEDs.

The scope of supply of the Smart Line Modules includes:

• DRIVE-CLiQ cable to connect to a Control Unit
• DRIVE-CLiQ cable for connection between the Control Unit and first Motor Module (type dependent)
• 1 set of warning labels in 30 languages
  (BG, CN, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HU, IE, IS, IT, JP, KR, LT, LV, MT, NL, NO, PL, PT, RO, RU, SE, SI, SK, TR)

The Smart Line Modules communicate with the higher-level control module via DRIVE-CLiQ. The control module in this case can be a CU320-2 or a SIMOTION D Control Unit. An external 24 V DC power supply is required to operate the Smart Line Modules.

General technical specifications

¹⁾ The DC link voltage is unregulated and load-dependent. For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.

¹⁾ The base-load current I_{H DC} is the basis for a duty cycle of 150 % for 60 s or I_{max DC} for 5 s with a duty cycle duration of 300 s.

²⁾ The specified power loss represents the maximum value at 100 % utilization. The value is lower under normal operating conditions.

³⁾ Total of all motor cables and DC link. Longer cable lengths for specific configurations are available on request. For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.

⁴⁾ Current required for reliably triggering protective devices.
