Accel/Decel Selection
The Accel/Decel rate can be obtained by a variety of methods. The default rate
is determined by
[Accel Time 1] and
[Decel Time 1]. Alternative
Accel/Decel rates can be made through digital inputs, RS485 (DSI)
communications and/or parameters. See the chart below for the override
priority.
RS485 Network Wiring
Network wiring consists of a shielded 2-conductor cable that is daisy-chained
from node to node.
Figure 12 - Network Wiring Diagram
Only pins 4 and 5 on the RJ45 plug should be wired. The other pins on the
PowerFlex 400 RJ45 socket contain power, etc. for other Rockwell
Automation peripheral devices and must not be connected.
