Ordering Notes
All SED2 drives come standard with FLN (P1) integration available and no additional parts are
required.
FLN Connections:
• P+ = Terminal 29
• N- = Terminal 30
• Do not terminate shield
Setting up Parameters for the SED2
Table 7 lists the parameters required for correct FLN communications and control of the SED2.
CAUTION:
Changes made to the parameters other than what is listed in Table 7 can result in
damaging the drive or building equipment.
Table 7. Set-up Parameters.
Parameter Number/Name Value
P0003: User access Level
Set to 3 to allow access to required parameters.
P2040: CB telegram off time
Set to 0 (watchdog disabled) to tell the SED2 to start looking for
communication via the setting of P2041.
P2041 (index 0): CB parameter
Set to 1 for FLN (P1) control.
(Set to 2 for FLN (N2) control.)
P0918: CB address
Set to 99 for (P1) addressing of the device.
(Set to 3 for (N2) addressing of the device.)
Unit must be powered down to establish P1 communications,
and then the address is assigned.
The address will go back to the default of 99 when the drive is
powered down.
P0700 (index 0)
Set to 6 tells the SED2 to look for a start command from P1 in
the auto mode.
P1000 (index 0)
Set to 6 tells the SED2 to look for its speed source from P1 in the
auto mode.
Since there is a limited life to EEPROM writes, set the Network Fault Indicator to 0 only when
troubleshooting a communications problem.
If a factory reset of parameters is desired set P0010 to 30 then set P0970 to 1.
