Note: If J1-14 and J1-15 are both Open, Preset Speed #1 is selected.
J1-16 OPEN causes an external trip to be received by control. The control will disable and
display external trip when programmed “ON”. When this occurs, the drive is disabled
and an external trip fault is displayed on the keypad display (also logged into the fault
log). If J1-16 is connected, you must set Level 2 Protection block, External Trip to “ON”.
