Feedback from the Drive – EFB

Pre-defined Feedback

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.

0102 SPEED
0103 FREQ OUTPUT
0104 CURRENT
0105 TORQUE
0106 POWER
0107 DC BUS VOLT
0109 OUTPUT VOLTAGE
0115 KWH COUNTER
0118 DI1-3 STATUS – bit 1 (DI3)
0122 RO1-3 STATUS
0301 FB STATUS WORD – bit 0 (STOP)
0301 FB STATUS WORD – bit 2 (REV)
NOTE: With Modbus, any parameter can be accessed using the format: 4 followed by the parameter number .

Mailbox Read/Write

The ACS320 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.
Table 59: Mailbox Protocol Reference
Name
Mailbox
Enter the number of the drive parameter to access .
Parameter
Mailbox Contains the parameter value after a read, or enter the desired
Data parameter value for a write .
Mailbox A binary value triggers a read – the value of the "Mailbox Parameter"
Read appears in "Mailbox data" .
Mailbox A binary value triggers a write – the drive value for the "Mailbox
Write Parameter" changes to the value in "Mailbox data" .
As noted above, Modbus provides direct access to all parameters using the format: 4 followed by the
