Accessing Drive Parameters and the Enter Command
■
Read Drive Parameters
To read the drive parameters that are not listed in the analog or digital objects, use AV29 and AV30 as shown in this
procedure:
1.
Write the desired Modbus register to AV29 in decimal value.
2.
Read the decimal value at the given register from AV30.
For example, to read the Frequency Reference Upper Limit, read from parameter d2-01 [Frequency Reference Upper
Limit].
Parameter d2-01 is located at Modbus register 0289H, which is decimal 649.
Set AV29 to "649."
Read AV30 to get the value.
■
Write Drive Parameters
To write the drive parameters that are not listed in the analog or digital objects, use AV29, AV30, and BV55 or BV56
as shown in this procedure:
1.
In AV29, write the desired Modbus register number in decimal format.
2.
In AV30, write the value that you want to put into the register set in AV29 in decimal format.
At this point the value is written to the drive, but the location is pending.
If necessary, write in more values this way, the drive will accept these settings by one of two methods:
• Set BV55 to "ON" to move data to active memory.
• Set BV56 to "ON" to move data into active memory and save to non-volatile memory.
For example, to reset the KWH Monitor, write a value of "1" to parameter o4-12 [kWh Monitor Initialization].
Parameter o4-12 is located at Modbus register 0512 (Hex.), which is decimal 1298.
Set AV29 to "1298."
Set AV30 to "1."
Set BV55 to "ON."
■
Enter Command
Enter Commands are only necessary to use AV29 and AV30 to access drive parameters. Enter commands are not
necessary to read or write to the other BACnet objects.
This section gives information about the Enter command.
Types of Enter Commands
The drive supports two Enter commands shown in
