Elevator Door Automatic Control System
The elevator control system is an important component of the modular elevator control system. The control and profile and PWM-pulse pattern generation are done by a microprocessor system. Position recognition, security and motor/inverter protection functions are implemented. Furthermore the microprocessor system has to establish the communication via the serial link (Multidrop protocol) with the motion command subsystem, from where it gets the door commands.
