Inverter apparatus having operation specifications determined by type of I/O block which is connected to basic control unit |
摘要 |
An inverter apparatus includes a basic control section including a main circuit which includes an inverter, and a control unit which controls the main circuit. The inverter apparatus also includes an I/O block which is connected to the basic control section, and is selected from a plurality of different types of I/O blocks. The I/O block includes an input/output interface. The input/output interface includes a signal connection terminal which transmits an input/output signal to/from the control unit. Operation management specifications of the main circuit are fixed independently of operation management specifications of the input/output interface. Operation specifications of the inverter apparatus change depending on the operation management specifications of the input/output interface, and are determined by the type of the I/O block which is connected to the basic control section, such that connecting the different types of I/O blocks to the basic control section causes the inverter apparatus to have different operation specifications.
