ABB DriveIT ACH550-UH - Analog Output Control; PID Control Setpoint Source

150 ACH550-UH User’s Manual
Serial Communication – EFB
1. More than 3 relays requires the addition of a relay extension module.
2. Applies only for Modbus using ABB Drive profile.
3. BACnet not defined at time of publication.
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 defined below.
1. Applies only for Modbus using ABB Drive profile.
2. BACnet not defined at time of publication.
Analog Output Control
Using the fieldbus for analog output control (e.g. PID setpoint) requires:
• Drive parameter values set as defined below.
• Fieldbus controller supplied analog value(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent.)
1. Applies only for Modbus using ABB Drive profile.
2. BACnet not defined at time of publication.
PID Control Setpoint Source
Using the fieldbus for the PID control setpoint requires:
• Drive parameter values set as defined below.
