DVESLY-4M-I

The DVESLY-4M-I
transistor panel is designed to control two wound-rotor induction motors and provides stepless impulse control with balanced impedance in the rotor circuit.
Given the unique characteristics of the crane we offer customized crane control systems in close cooperation with the end-user and customer.

Application range The DVESLY-4M-I transistor panel is applied on bridge cranes, gantry cranes, portal cranes, etc. on the following mechanisms:
  • Traveling of a two-motor trolley;
  • Traveling of a two-motor bridge;
  • Trolley slew motion and other horizontal two-motor axis.
Operating principle

The principle of operation is based on the change in the value of active resistance in the rotor circuit via PWM control, and provides constant motor speed without the use of mechanical encoder. PWM with speed control allows to maintain a given motor speed regardless of the applied torque. Control mode DVESLY-3M-I corresponds to the frequency converter drive.

Functions and capacity The TEDF-4M-I panel has the following functions:
  • provides contactless switching of power mains on motor stator windings to ensure reverse rotation by means of cross-switch of two phases of stator windings;
  • provides contactless PWM of constant resistors section in order to regulate parametrized permanent speed of up to 1:10 of maximum speed in both directions;
  • provides rotor circuit control;
  • provides parametrized time delays between steps activation to decrease dynamic loads on the motor and crane mechanical assemblies;
  • provides parametrized motor protection from peak operating and starting currents in the stator circuit;
  • provides deactivation of all system devices in case of inadmissible voltage parameters of power mains;
  • deactivates the motor as a result of tripping-over on the end switch with a possibility to move in the opposite direction;
  • provides a indication of the main parameters and the status of the drive on the integrated display;
  • provides easy parameterization via the built-in keyboard and display.
Warranty

Warranty period of this thyristor drive is 18 months from the date of crane commissioning, but does not exceed 24 months from the date of manufacture.
