SIMOTRAS HD Operating Instructions
3 Description
3.1 Applications
SIMOTRAS HD converters in the 6SG70 series are fully digital compact converters and have been
developed for regulating three-phase lifting gear motors with slipring rotors in the output range up to
580 kW and for higher-level control of the drive.
For
-
lifting gear
-
s lewing gear
-
luffing gear
-
trolley travel gear
-
travel gear
-
auxiliary-range gearboxes
The benefits are:
-
very efficient drive unit solutions in older systems
-
extremely simple retrofitting resulting in significant improvements to existing systems
-
low modernization costs as existing components such as motors, resistors, cables and
cabinets can continue to be used
-
fast, variable and user-friendly solution with low system standstill times
-
very cost-effective solution for new systems
-
low requirements for contactor controls and external interlocks, as important control functions
are already integrated
-
little planning and configuration work required
-
cost-saving due to short assembly and commissioning times thanks to connection-ready
compact converter technology
-
very smooth travel, which helps prevent system wear
-
very high level of control quality by utilizing the particular electrical advantages of the slipring
motor
-
very high level of control dynamics with the use of stator phase-angle control
-
all standard lifting components and interfaces can be used
-
no special technologies required!
3.2 Design
Series 6SG70 SIMOTRAS HD converters are characterized by their compact, space-saving
construction. Their compact design makes them particularly easy to service and maintain since
individual components are readily accessible. The electronics box contains the basic electronic
circuitry as well as any supplementary boards.
All SIMOTRAS HD converters are equipped with a PMU simple operator panel mounted in the
converter door. The panel consists of a five-digit, seven-segment display, three LEDs as status
indicators and three parameterization keys. The PMU also features connector X300 with a USS
interface in accordance with the RS232 or RS485 standard. The panel provides all the facilities for
making adjustments or settings and displaying measured values required to start up the converter.
The OP1S optional converter operator panel can be mounted either in the converter door or
externally, e.g. in the cubicle door. For this purpose, it can be connected up by means of a 5 m long
cable. Cables of up to 200 m in length can be used if a separate 5 V supply is available. The OP1S
is connected to the SIMOTRAS HD via connector X300.
The OP1S can be installed as an economic alternative to control cubicle measuring instruments
which display physical measured quantities.
The OP1S features an LCD with 4 x 16 characters for displaying parameter names in plaintext.
German and English can be selected as the display languages.
The OP1S can store parameter sets for easy downloading to other devices.
