142 ACH580 E-Clipse bypass and packaged drive user manual
Embedded fieldbus
For the 1xxxx registers:
• Additional discrete inputs are added sequentially.
The system supports the following Modbus function codes for discrete inputs:
3xxxx Mapping – Modbus Inputs. The drive maps the following information to the
3xxxx Modbus addresses called Modbus input registers:
• Any user defined analog inputs.
The following table summarizes the input registers:
The ACH580 supports the following Modbus function codes for 3xxxx registers:
4xxxxx Register Mapping. The drive maps its parameters and other data to the
4xxxxx holding registers as follows:
• 400001…400099 map to drive control and actual values. These registers are
described in the table below.
• 400101…465535 map to drive parameters or bypass parameters. Register
addresses that do not correspond to drive parameters are invalid. If there is an
