SIMOREG DC Drives – Siemens Drive Technologies


The Siemens Motor Regulator (SIMOREG) is a state of the art, microprocessor based DC drive controller. This drive controller converts a three-phase, 50/60 Hz supply voltage into six pulse adjustable voltage to operate a DC motor. Output armature voltage varies directly with speed reference to provide constant torque operation from zero speed to base speed. Above base speed, the motor shunt field current may be decreased to further increase speed and provide a constant horsepower output up to maximum speed.

The SIMOREG DC drive controller is designed to provide precise motor speed control over a wide range of machine parameters and load conditions. This software based controller will serve well as a packaged drive or as part of a drive system.

Horsepower ranges include 1-250HP at 230VAC, 2-1750HP at 460VAC input and 1500HP and higher at 600/650V AC input. All HP ratings are available as regenerative or non-regenerative drive controllers. Listed below are standard features, a partial list of adjustments, display parameters, service conditions, diagnostics, and protection features.

SIMOREG DC Drives,the first DC drives to fit within Siemens Totally Integrated Automation strategy, SIMOREG drives have been completely integrated into the Siemens system environment. Engineering/configuration and programming, as well as communications, share a common database – saving time and expense.

The SIMOREG DC-Master family features an output range from 5 to 3,350 HP (3.7 to 2,508 kW).

SIMOREG DC Drives Features

  • May be fully integrated into any automation environment
  • Expandable in a modular fashion – from the standard application up to high-performance solutions
  • Extension by parallel connection up to 18,000 A
  • Rated supply voltages from 400 V to 950 V
  • Short and fast commissioning as all of the settings are fully electronically parameterized
  • Unified operator control philosophy

SIMOREG DC Drives Industry Benefits

■  Master and bus systems relieved, and in many cases a separate PLC is not required

The open and closed-loop control are realized directly in the drive.

■  Optional user-friendly OP1S operator panel guarantees fast and straight forward operator control

For example, when up-reading and downloading parameter sets online and offline. The 4-line plain text display with 16 characters is clear and functional. The OP1S can be universally used for all SIMOREG DC-MASTER and SIMOVERT MASTERDRIVES drive converters.

■  Direct access to a new interface to configure parallel circuits for redundant drive systems

The complete system will still function even if one or several drives fail.

■  All SIMOREG DC-MASTER units are already pre-configured in the factory

The equipment-specific parameters no longer have to be set, and the adaptation to the particular application (e.g. the load resistor for optimum current actual values or the terminating resistor for perfect communications) are also realized fully electronically using parameters. This means that they can be immediately used when service is required. SIMOREG DC-MASTER – the more cost-effective solution even before it goes into operation.

■  Rejuvenate older DC solutions using the SIMOREG CM unit

The Control Module permits a favorably-priced and efficient retrofit solution – no matter whether retrofitting or upgrading.

■  SIMOREG products are internationally certified and fully compliant with the most important standards and regulations

From the EN European Standard up to IEC/VDE. CE marking, UL, cUL and CSA certification make the SIMOREG DC-MASTER a true global player.

■  Simply integrated into automation solutions

e.g. using the PROFIBUS communication interface provided as standard together with various analog and digital interfaces.
