172 ACH580 E-Clipse bypass and packaged drive user manual
Fieldbus adapter
Bypass relay output control
Using the fieldbus for relay output control requires:
• Bypass parameter values set as defined below.
• Fieldbus controller supplied, binary coded, relay command(s) in the appropriate
location. (The location is defined by the Protocol Reference, which is protocol
dependent.)
Note: Relay status feedback occurs without configuration as defined below.
Communication fault
When using fieldbus control, specify the bypass action if communication is lost.

Fault Handling
The ACH580 or E-Clipse provides fault information as follows:

page 185 for a complete description.
• Parameters 0401 LAST FAULT, 0402 PREVIOUS FAULT1 and 0403 PREVIOUS
FAULT2 store the most recent faults.
