Illustration 28: Structure Diagram of the Control System
The main functions of the main control system include:
Digital input and output
Analog input and output
PWM control signal generation of each power cell
Encoding and decoding of the control signal
System self-diagnosis
Delivery of various implementation instructions
Collection and handling of various failures
Communication with external systems
To enhance the flexibility at the site application, a PLC is used for the logical processing of the internal switching signals, site opera-
tion signals, and status signals of the medium-voltage drive. The VACON® 1000 medium-voltage drive uses a high-quality PLC to:
Accomplish the input and output drive signal control
Protection and interlocking
External failure detection
Communication with the main control system
Control of the human-machine interface
The HMI (Human-machine interface) is based on a high-definition liquid-crystal touch-type screen. It is easy to operate and is used
to set functional parameters, display and record the system status, operation status, and faults through the connection to the PLC.
