SIMOTRAS HD is a fully-controlled digital, three-phase thyristor controller in a compact design with stator phase control and electronic field reversal with ratings of between 20kW and 580kW for the open and closed-loop control of slip-ring motors for cranes and hoisting gear.
All converters are equipped with a basic PMU operator panel in the door of the unit. The PMU can be used to perform all of the adaptations, settings and measured value displays required for commissioning. The basic unit can also be operated via its serial service interface using a commercially available PC and suitable software. All of the unit settings (e.g. controller parameters, limits ...) are stored in the unit in a non-volatile memory.
Hoisting, swiveling, luffing, trolley and long travel gears as well as single and multi-motor drives
Steelworks and foundries (available up to an ambient temperature of 65°)
* depending on the version and type
Voltage and power range*
3-ph. 110 V - 500V AC, +/- 10%, 20 - 580 kW
Closed-loop control types*
Load-dependent, continuously variable speed control from -60% to +60% – and also controlled travel using rotor resistors
4-Q drive using stator phase control with electronic rotating field reversal
Compact designas the open-loop control is integrated in the drive
Favorably-priced solution in the retrofit areaby using slip-ring rotor motors that already exist in the plant or system
Simple integration into the existing automation environmentusing the optional PROFIBUS interface
