3-8 Programming and Parameters
Basic Program Group (continued)
P036 [Start Source] Related Parameter(s): P037, P042, A166, d301
Stop drive before changing this parameter.
Sets the control scheme used to start the drive when in Auto/Remote mode.
Refer to Start and Speed Reference Control
on page 1-24 for details about how other drive settings
can override the setting of this parameter.
Important: For all settings except options 3 and 6, the drive must receive a leading edge from the
start input for the drive to start after a stop input, loss of power or fault condition.
Options 0 “Keypad” Integral keypad controls drive operation.
• I/O Terminal 01 = Stop: Coast to Stop
• I/O Terminal 02 = Not Used
• I/O Terminal 03 = Not Used
1 “3-Wire” I/O Terminal Block controls drive operation.
• I/O Terminal 01 = Stop: Per P037
[Stop Mode]
• I/O Terminal 02 = Start
• I/O Terminal 03 = Direction
2 “2-Wire” I/O Terminal Block controls drive operation.
• I/O Terminal 01 = Stop: Coast to Stop
• I/O Terminal 02 = Run FWD
• I/O Terminal 03 = Run REV
3 “2-W Lvl Sens”
(Default)
I/O Terminal Block controls drive operation.
• I/O Terminal 01 = Stop: Coast to Stop
• I/O Terminal 02 = Run FWD
• I/O Terminal 03 = Run REV
Drive will restart after a “Stop” command when:
• Stop is removed and Run FWD is held active
4 “2-W Hi Speed” I/O Terminal Block controls drive operation.
• I/O Terminal 01 = Stop: Coast to Stop
• I/O Terminal 02 = Run FWD
• I/O Terminal 03 = Run REV
Outputs are kept in a ready-to-run state. The drive will
respond to a “Start” command within 10 ms.
Important: There is greater potential voltage on the output
terminals when using this option.
5 “Comm Port” Remote communications controls drive operation.
• I/O Terminal 01 = Stop: Coast to Stop
• I/O Terminal 02 = Not Used
• I/O Terminal 03 = Not Used
6 “2-W Lvl/Enbl” I/O Terminal Block controls drive operation.
• I/O Terminal 01 = Function Loss: Fault and Coast to Stop
• I/O Terminal 02 = Run FWD
• I/O Terminal 03 = SW Enable
Drive will restart after a “Stop” command when:
• Stop is removed and Run FWD is held active

ATTENTION: Hazard of injury exists due to unintended operation. When
P036 [Start Source] is set to option 3 or option 6, and the Run input is
maintained, the Run inputs do not need to be toggled after a Stop input or a
fault clear for the drive to run again. The drive will stop only when the stop
command is maintained or the drive is faulted.
