motor to coast to a stop. The fault or coast to stop operation of
the MOL input terminal is selected by parameter 77-External Trip
Select. The selection of pull- up or pull-down logic is set by
jumper J19.
Jumper J19 Input Selection
Jumper J19 is a pin-jumper selector located to the left and below
the control terminal strip (See Figure 2-2). Five jumper positions
are available and are arranged in one group of three positions
and one group of two positions with one shorting jumper in each
group. The group of two located to the right hand side are used
to select the active state of the opto isolated inputs (Pull-Up or
Pull-down Logic). The group of three located to the left hand
side are used to select the type of analog speed command signal
to be used. The available analog speed command signals are
0-5VDC, 0-10VDC, 0-20 mA, and 4-20 mA. A 5kohm 1/2 watt
potentiometer can be used by configuring for 0-5VDC. The
available jumper settings are shown in the following diagram:
