C108 [Start Source 2]
Stop drive before changing this parameter.
Sets the control scheme used to start the drive when in Comm Control and the communication network commands the drive to run from Local Control. This function is normally used
by Point 79 of a P1-FLN. Refer to
Start and Speed Reference Control on page 37
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.
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.
IMPORTANT
There is greater potential voltage on the output terminals when using this option.
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.
