ACH550 E-Clipse Bypass User’s Manual 2-87
Embedded fieldbus
Serial communication configuration – drive
Setting 9802 automatically sets the appropriate default values in parameters that
define the communication process. These parameters and descriptions are defined
below. In particular, note that the station ID may require adjustment.
Bypass
Parameter
Description
EFB Protocol Reference
Modbus N2 FLN BACnet
1625 COMM CONTROL 1625 = 0 (Drive Only) for control signals (Start/Stop &
enables) to go to drive only.
1625 = 1 (System) for control signals to go to the system
(drive or bypass, depending on keypad mode selection)
5301 DV PROTOCOL ID
Contains the identification
and program revision of the
protocol.
Do not edit. Any non-zero value entered for parameter
9802 COMM PROT SEL, sets this parameter
automatically. The format is: XXYY, where xx = protocol
ID, and YY = program revision.
5302 DV STATION ID
Defines the drives node
address of the EIA 485 link.
Set each bypass on the
network with a unique value for
this parameter.
Default: 1
Note: For a new address to
take affect, the system power
must be cycled OR 5302 must
first be set to 0 before selecting
a new address. Leaving 5302 =
0 places the EIA 485 channel
in reset, disabling
communication.
Sets MS/TP MAC ID. A
temporary value of 0
places the protocol
channel in reset.
Default: 128
5303 EFB BAUD RATE
Defines the communication
speed of the EIA 485 link in
kbits per second (kbits/s).
1.2 kbits/s
2.4 kbits/s
4.8 kbits/s
9.6 kbits/s
19.2 kbits/s
38.4 kbits/s
57.6 kbits/s
76.8 kbits/s
Default: 9.6
