Mailbox Read/Write
The MD5 provides a “Mailbox” function to access parameters
thathavenotbeenpre-denedbytheprotocol.Using
mailbox,anydriveparametercanbeidentiedandread.
Mailbox can also be used to adjust parameter settings by
writingavaluetoanyparameteridentied.Thefollowing
table describes the use of this function.

Name Description
Protocol Reference
Modbus1 N2 FLN BACnet
Mailbox Parameter
Enter the number of the drive parameter to access. Does not apply. AO19 95 AV25
Mailbox Data
Contains the parameter value after a read, or enter the desired
parameter value for a write.
AO20 96 AV26
Mailbox Read
A binary value triggers a read – the value of the “Mailbox
Parameter” appears in “Mailbox data”.
BO19 97 BV15
Mailbox Write
A binary value triggers a write – the drive value for the
“Mailbox Parameter” changes to the value in “Mailbox data”.
BO20 98 BV16
1. As noted above, Modbus provides direct access to all parameters using the format: 4 followed by the parameter number.
