Connecting and installing RS485 interfaces
Serial Interfaces of MOVIDRIVE® B
4.1.2
Connection using terminals X13:10 and X13:11
Another RS485 interface is provided via terminals X13:10 and X13:11. This RS485
interface can be used to interconnect several MOVIDRIVE
®
B units and connect the
other options at the same time.
• Interface adapter UWS11A (RS232 signals to RS485 signals)
• DOP11B operator terminal
• Other SEW drives, such as MOVIMOT
®
• Other interface adapters, such as COM server or other RS485 master devices

Electrical isolation
• The RS485 interface X13 is not electrically isolated. Do not connect more than 32
MOVIDRIVE
®
B units with one another,
Cable specification
• Use a 4 core twisted pair and shielded copper cable (data transmission cable with
braided copper shield). The cable must meet the following specifications:
– Cable cross section 0.25 - 0.75 mm
2
(AWG 23 - AWG 19)
– Cable resistance 100 - 150
Ω
at 1 MHz
– Capacitance per unit length
≤
40 pF/m at 1 kHz
Cable length
• The permitted total cable length is 200 m (656 ft).
Shielding
• Connect the shield to the electronics shield clamp on the inverter or higher-level
controller and make sure it is connected over a wide area at both ends.
Baud rate
• The baud rate is set to 9.6 baud by default.
Terminating
resistor
• Dynamic terminating resistors are installed.
Do not connect any external terminat-
ing resistors.
