Possible settings via DIP switch

[11-1] DIP switch

Lenze setting: All DIP switches are in the "OFF" position

Tip!
The current DIP switch settings are displayed in code

.

Bit 15 indicates that the setting of the DIP switches has been accepted when the device or

the 24V supply has been switched on.

11.2.1

Activating the bus terminating resistor

The system bus must be terminated between CAN low and CAN high at the first and last physical

node each by a resistor (120 Ω). The 8400 controller is provided with an integrated bus terminating

resistor, which can be activated via the unlabelled DIP switch.
DIP switch position ("R"):

• OFF = bus terminating resistor is inactive
• ON = bus terminating resistor is active

Switch position:

The following can be set via the front panel DIP switches:

• Bus terminating resistor

Switch: "R"

• Baud rate

Switch: "a" ... "d"

• Node address

Switch: "1" ... "64"

Note!

• The DIP switch settings are accepted if a node address is unequal zero when the device

or the 24-V supply is switched on by the DIP address.

• If all DIP switches are OFF when the device or the 24 V supply is switched on, the

setting of the baud rate and node address are read out of the parameter

set/parameter.
