Serial Communication – EFB
* = Active low
For the 0xxxx registers:
• Status is always readable.
• Forcing is allowed by user configuration of the drive for fieldbus control.
• Additional relay outputs are added sequentially.
The ACH550 supports the following Modbus function codes for coils:
1xxxx Mapping – Modbus Discrete Inputs. The drive maps the following
information to the 1xxxx Modbus set called Modbus Discrete Inputs:
• Bit-wise map of the STATUS WORD (selected using parameter 5305 EFB CTRL
PROFILE). The first 32 inputs are reserved for this purpose.
• Discrete hardware inputs, numbered sequentially beginning with input 33.
The following table summarizes the 1xxxx reference set:
00037 Relay Output 5 Relay Output 5 Relay Output 5
00038 Relay Output 6 Relay Output 6 Relay Output 6
