ACH580 E-Clipse bypass and packaged drive user manual 171
Fieldbus adapter
Start/stop direction control
Using the fieldbus for start/stop control of the system requires:
• Bypass parameter values set as defined below.
• Fieldbus controller supplied command(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent.)
Miscellaneous system control
Note: Control of system commands is dependent upon the setting of bypass
parameter 1625.
Using the fieldbus miscellaneous system control requires:
• Bypass parameter values set as defined below.
• Fieldbus controller supplied reference word(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent.)

1) For Modbus TCP, the protocol reference can depend on the profile used, hence two columns in
these tables. One column refers to the ABB Drives profile, selected when parameter 51.02 = 0
(ABB Drives-Classic) or 51.02 = 1 (ABB Drives-Enhanced). The other column refers to the DCU
profile selected when parameter 51.02 = 2 (Transparent-16-Bit). See ABB drives profile technical
data section on page 175.
