English-10 PowerFlex 400 Adjustable Frequency AC Drive Quick Start
(1)
Important: I/O Terminal 01 is always a coast to stop input
except when P036 [Start Source] is set to option 1 “3-Wire” or
6 “2-W Lvl/Enbl”. 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 or enable input.
(2)
Two wire control shown. For three wire control use a momentary input on I/O Terminal 02 to command a
start. If reverse is enabled by A166, use a maintained input for I/O Terminal 03 to change direction.
(3)
When using an opto output with an inductive load such as a relay, install a recovery diode parallel to the relay as
shown, to prevent damage to the output.
(4)
When the ENBL enable jumper is removed, I/O Terminal 01 will always act as a hardware enable, causing a
coast to stop without software interpretation.
(5)
Most I/O terminals labeled “Common” are not referenced to the safety ground (PE) terminal and are designed to
greatly reduce common mode interference. On Frame D and E drives, Analog Common 1 is referenced to
ground.
(6)
Common for Analog Input 2 (AI2). Electronically isolated from digital I/O and opto output. Not to be used with
Analog Input 1 (AI1), Analog Output 1 (AO1) or Analog Output 2 (AO2). With Analog Input 2, provides one fully
isolated analog input channel.
