Drive parameter group 53 10
Drive parameter group 53 defines features unique to bacnet as described below 10
Start up 10
Ach550 bacnet user s manual 11 11
Changes made to drive parameter group 53 efb protocol do not take affect until you perform one of the following 11
Cycle the drive power off and on or 11
Enable bacnet protocol set drive parameter 9802 11
It should read x5xx where x is any value 11
Note if you cannot see the desired selection on the panel your drive does not have that protocol software in the application memory 11
Quick start sequence 11
Set parameter 5302 to 0 and then back to a unique mac id or 11
Start up 11
The following steps summarize the process for enabling and configuring bacnet on the ach550 11
To confirm this selection read drive parameter 5301 11
Use the reinitializedevice service 11
Activate drive control functions 12
Controlling the drive 12
Ach550 bacnet user s manual 13 13
Drive parameter values set as defined below 13
Fieldbus controller supplied command s in the appropriate location 13
Fieldbus controller supplied reference word s in the appropriate location 13
Input reference select 13
Miscellaneous drive control 13
Note ext1 ref 1 ext 2 ref 2 ref 2 normally used for pid setpoint commands 13
Start stop direction control 13
Start up 13
Using the fieldbus for miscellaneous drive control requires 13
Using the fieldbus for start stop direction control of the drive requires 13
Using the fieldbus to provide input references to the drive requires 13

Analog output control 14
Communication fault 14
Drive parameter values set as defined below 14
Fieldbus controller supplied analog value s in the appropriate location 14
Fieldbus controller supplied binary coded relay command s in the appropriate location 14
Only make these drive programming changes if you require control via bacnet 14
Relay output control 14
Start up 14
Using the fieldbus for analog output control requires 14
Using the fieldbus for relay output control requires 14
When using fieldbus control specify the drive s action if serial communication is lost 14

Drive parameter bacnet access point 15
Drive parameter value bacnet access point 15
Feedback from the drive 15
Has a resolution of 0 sec which means that in the drive and in the mailbox the value 1 0 seconds so a mailbox value of 10 translates to 1 second a mailbox value of 300 translates to 30 seconds etc refer to the parameter listing in the ach550 user s manual for each parameter s resolution and units of measure 15
Inputs to the controller drive outputs have pre defined meanings established by the protocol this feedback does not require drive configuration the following table lists a sample of feedback data for a complete listing see input word point object listings in the technical data section 15
Mailbox read write 15
Note relay status feedback occurs without configuration as defined below 15
Note you must read and write mailbox values using the drive s internal scaling for example the parameter 2202 15
Pre defined feedback 15
Relay 1 3 status bi0 bi1 bi2 15
Relay 4 6 status bi3 bi4 bi5 15
Start up 15
The ach550 provides a mailbox function to access parameters that have not been pre defined by the protocol using mailbox any drive parameter can be identified and read mailbox can also be used to adjust parameter settings by writing a value to any parameter identified the following table describes the use of this function 15
