2.4.1 FILTER BOARD
This two-stage filter consists of common and differential mode elements. It attenuates the Inverter noise
produced on to the mains supply. Mains supply is applied to terminals L1, L2 (N) and L3.
2.4.2 POWER BOARD
DC link capacitors smooth the dc voltage output prior to the Inverter power stage. The IGBT (Insulated Gate Bi-
polar Transistor) output stage converts the dc input to a three phase output used to drive the motor.
2.4.3 CONTROL BOARD
2.4.3.1 Processor
The processor provides for a range of analog and digital inputs and outputs, together with their reference
supplies. For further details refer to Chapter 11: “Technical Specifications” - Control Terminals.
The I/O configuration switches (SW1 & SW2) on the control board can be seen through the outer
casing of the Inverter when the blank cover, the Operator Station, or the Technology Box option is
removed. These switches configure the analog i/o terminals. Refer to Chapter 6: “Programming
Your Application” - ANALOG INPUT and ANALOG OUTPUT.
2.4.3.2 Technology Box Interface
This is a multi-way connector and processor bus interface with control signals allowing various technology box
options to be fitted to the Inverter.
2.4.3.3 Operator Station Interface
This is a non-isolated RS232 serial link for communication with the Operator Station. Alternatively, a PC running
Elettronica Santerno “SINUS/ISD Configuration Program” Windows-based configuration software (or some other
suitable PC programming tool) can be used to graphically program and configure the Inverter.
