Embedded fieldbus
Relay output control
Using the fieldbus for relay output control requires:
• Drive 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. More than 3 relays requires the addition of a relay extension module.
For example: To control relays 1 and 2 using serial communication:
Set parameters 1401
RELAY OUTPUT
1 and 1402
RELAY OUTPUT
1 = 35 (

).
Note: Relay status feedback occurs without configuration as defined below.
