Mounting/Installation Instructions
Cable length
• The permitted total cable length depends on the baud rate setting of the system bus:
– 125 kbaud
→
500 m
– 250 kbaud

40 m
Terminating
resistor
• Switch on the system bus terminating resistor at the start and end of the CAN 2 sys-
tem bus connection (MOVIDRIVE
®
B, DIP switch S12 = ON; MOVITRAC
®
B, DIP
switch S1 = ON). For all other devices, switch off the terminating resistor
(MOVIDRIVE
®
B, DIP switch S12 = OFF; MOVITRAC
®
B, DIP switch S1 = OFF). If
the MOVI-PLC
®
advanced
DH.41B controller is, for example, located at the end of
the CAN 2 system bus, you have to connect a terminating resistor of 120 O between
pins X32:2 and X32:3 (for CAN 1: terminating resistor between pins X33:2 and pin
X33:3).

Connection of the RS485 interface (connector X34)
You can connect one of the following devices to the RS485 interfaces COM1/2 (connec-
tor X34):
• DOP11A operator terminals
• Gearmotor with integrated frequency inverter MOVIMOT
®
STOP!
• There
must not
be any potential displacement between the units connected via the
CAN 2 system bus.
• There
must not
be any potential displacement between the units connected via the
CAN 1 system bus.
• Take suitable measures to avoid potential displacement, such as connecting the
unit ground connectors using a separate cable.
STOP!
• There must not be any potential displacement between the units connected via the
RS485. Take suitable measures to avoid a potential displacement, e.g. by connect-
ing the unit ground connectors using a separate lead.
• Dynamic terminating resistors are installed.
Do not connect any external termi-
nating resistors.
