«Upgrading the control system for point operating mechanisms (deviators) of rolling mill».
Our company’s engineers have performed the activities on design, delivery and commissioning of control system for point operating mechanisms (deviators) 3.1, 3.2, 4.1, 4.2, 5.1, 5.2 of rolling mill. This control system was designed to control the transfer of initial breakdown from one feed line to another.
The new frequency converters were installed. To allow for making the adjustments, the point position control loop was carried over to the existing control system, based on Siemens S7-400 controller. The speed loop in the frequency converter was designed as the one with a feedback from the existing engine-mounted resolver position indicator.
The required rapidity of transfer of points from one position to another was achieved too.
