Bit 6: Checksum Type
Bit 7: Little endian or big endian used in MODBUS type drive
Bit 8: Four wires/two wires for RS-485 communication
P-77 (TD)
Transmit delay

DEC
The time delay used by the drive when responding to a command that requests a response. Typically this
is needed when using the 2-wire RS-485 interface (half-duplex). Because the same wires are used to both
receive and transmit a time delay is usually needed to allow transition time.
P-78 (BR)
Baud rate
Data Range
Default
Unit
Data type
1 - 5

DEC
This parameter sets the bit rate (baud) for serial communications. At power up a drive will send its power-
up packet detected after 1 second and the drive is configured for SCL or Q operation (see PM command)
the drive will set the baud rate according to the value stored in the Baud Rate NV parameter. A Host
system can set the baud rate at anytime using this command.
1:
9600bps
2:
19200bps
3:
38400bps
4:
57600bps
5: 115200bps
P-79 (DA)
RS-485 Address
Data Range
Default
Unit
Data type
1 - 32

DEC
The individual drive address character for multi-drop RS-485/MODBUS communications. This command
is not required for single-axis (point-to-point) or RS-232 communications.
