Communications
The
TE Series
starter is shipped from the factory ready to accept
RS-485 Serial Communications using Modbus RTU protocol. F065 –
F067 are used to set the communications parameters in the starter for
use by the adaptor module. F068 determines how the Start / Stop
functions work through the communications port. Consult factory for
register mapping document.
F065 = Communications
Factory Setting = 0 (Disabled)
Range = 0 – 2
This enables serial communications with remote monitoring and
control systems and sets the format for Modbus RTU protocol.
Once Enabled, the local start / stop inputs are altered to avoid
inadvertent starting. See F068 for details.
F065 = 0
, communications are disabled.
F065 = 1
, uses the std 11 bit Modbus format w/ parity bit.
F065 = 2
, a non-standard 10-bit format without a parity bit is
used to accommodate some systems using this method.
F066 = Baud Rate
Factory Setting = 9.6 KB
Range = 4.8 to 19.2 KB
Set value to either 4.8 KB, 9.6 KB or 19.2 KB and match the
setting of the host device.
F067 = Modbus Address
Factory Setting = 1
Range = 1 – 247
Using Modbus communications protocol, up to 247
TE Series
starters can be networked using RS485 standard
communication, each having a unique address. Two devices with
the same address will result in a communications error.
F068 = Remote Starter Control
Factory Setting = 0 (disabled)
Range = 0 – 3
This determines how the
TE Series
starter is to be controlled
when using serial communications.
When F068 = 0,
the starter can be monitored by the Comm.
port, but not controlled.
When F068 = 1
, the starter will be controlled by the
communications port. In addition, the Start / Stop inputs are
altered as follows: The hard-wired Start command is put in
“
AND”
logic with the Comm. port; both Start commands must be
on for the TE to start. The Stop function is put in “
OR”
logic;
either the Comm. port Stop command
OR
the hard-wired Stop
will cause the TE to stop.
When F068 = 2
, the TE starter is in full control of the Comm. port
only. Local Start / Stop inputs become completely inactive. Use
this function only when controlled shutdown is a priority.
When F068 = 3
, the TE starter will change the function of the
Jog / Remote Input
to cause a switch between the functions of
setting
0
and setting
1
as listed above. When the input is open,
the starter will respond to the Comm. port as per setting F068=0
above. When the
Jog / Remote Input
is closed, the starter will
respond as per setting F068=1 above. Use this function if it is
necessary to have a return to local start/stop control should the
communications system fail or become disconnected.

Special Note when using Serial Communication:
When F068 = 3, the function of the Jog / Remote Input
on TB-1 terminals 7 and 8 will change. Closing the
Input will cause the Comm. port control to function as
per setting F068=1. Leaving the input open will cause
the Comm. port to function as per setting F068=0.
When F068 = 1, 2 or 3, the Jog function will cease to
operate. Since Jogging is a local function, set F068 to 0
when using it.
