Chassis format – Line Modules
Active Line Modules
■
Overview
A wide range of single-axis Line Modules and Motor Modules
with graded current/power ratings can be supplied:
•
Active Line Modules: Single-axis version in chassis format
with rated power from 132 kW to 300 kW
•
Single Motor Modules: Single-axis version in chassis format
with rated output currents of 210 A to 490 A
In principle, all Single Motor Modules can operate on Active Line
Modules for the corresponding voltage range.
The self-commutated infeed/regenerative feedback units (with
IGBTs in infeed and regenerative feedback directions) generate
a regulated DC link voltage. This means that the connected
Motor Modules are decoupled from the line voltage. Line voltage
fluctuations within the permissible supply tolerances have no
effect on the motor voltage.
If required, the Active Line Modules can also provide reactive
power compensation.
Active Line Modules are designed for connection to grounded
TN and TT supply systems and to non-grounded IT supply
systems.
In order to operate an Active Line Module, it is absolutely
essential to use the appropriate Active Interface Module.
■
Design
The Active Line Modules in chassis format feature the following
interfaces as standard:
•
1 line 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
•
2 PE connections
The status of the Active Line Modules is indicated via two
multi-color LEDs.
The scope of supply of the Active Line Modules includes:
•
Frame sizes FX and GX:
- 0.60 m (1.97 ft) DRIVE-CLiQ cable for connection to the
CU320-2 Control Unit or SINUMERIK NCU
■
Integration
The Active Line Module receives its control information via
DRIVE-CLiQ from:
•
CU320-2 Control Unit
•
SINUMERIK 840D sl with
- NCU 710.3B PN
- NCU 720.3B PN
- NCU 730.3B PN
- Numeric Control Extensions NX10.3/NX15.3
