Relay Output Control - Daikin ACS320 Operation Manual

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 .)
Table 53: Relay Output Control Protocol Reference
Drive Parameter
1401 RELAY OUTPUT 1
1402 RELAY OUTPUT 2
1
1403 RELAY OUTPUT 3
1
1410 RELAY OUTPUT 4
1
More than 1 relay requires the addition of a relay extension module
1
•
For example: To control relays 1 and 2 using serial communication:
Set parameters 1401 RELAY OUTPUT 1 and 1402 RELAY OUTPUT 1 = 35 (COMM) .
Then, for example using N2:
• To turn Relay 1 On: Force object B07 to On .
• To turn Relay 2 On: Force object B08 to On .
• To turn both Relay 1 and 2 On: Force objects B07 and B08 On .
NOTE: Relay status feedback occurs without configuration as
