46 Operation
ATTENTION: For frequent starts and stops, short the
inhibit terminals, decelerate to a minimum speed, or
apply a dynamic brake to the motor. Do not use any of
these methods for emergency stopping. They may not
stop a drive that is malfunctioning. Removing AC line
power (both L1 and L2) is the only acceptable method
for emergency stopping.

Auto mode
IMPORTANT:
If you run the drive in AUTO mode using
an external current signal, you must recalibrate the MIN
SPD trimpot to offset any motor drift caused by the input
signal.
IMPORTANT: When switching between MANUAL and
AUTO (0-10 VDC) modes, you must balance the MIN
SPD trimpot setting for both operating modes.
Set the mode selector switch to AUTO if you wish to
follow an external signal, independent of the speed adjust
knob setting. In AUTO mode, the drive will control motor
speed in proportion to either a 0 – 10 VDC analog voltage
or a 4 – 20 mADC current signal. You must set select
switch SW504, SIGNAL SOURCE SELECT, to either
VOLTAGE or CURRENT, depending on your signal input.
