Important:
I/O Terminal 01 is
always a coast to stop input except
when P036 [Start Source] is set to
“3-Wire” control. In three wire
control, I/O Terminal 01 is controlled
by P037 [Stop Mode]. All other stop
sources are controlled by P037
[Stop Mode].
Important:
The drive is shipped with
a jumper installed between I/O
Terminals 01 and 11. Remove this
jumper when using I/O Terminal 01
as a stop input.
(2)
Two wire control shown. For three
wire control use a momentary input
on I/O Terminal 02 to
command a start. Use a maintained
input
for I/O Terminal 03 to
change direction.
Refer to the PowerFlex 4
User Manual
on CD for
detailed I/O wiring examples.
