13 TRIMPOT ADJUSTMENTS
The drive contains trimpots
which are factory set for
most applications. See
Figure 4, on page 20, for the
location of the trimpots and
their approximate factory
calibrated positions. Some
applications may require
readjustment of the trimpots
in order to tailor the drive for
a specific requirement. The trimpots may be readjusted as described below.
WARNING! If possible, do not adjust trimpots with the main power applied. If
adjustments are made with the main power applied, an insulated adjustment
tool must be used and safety glasses must be worn. High voltage exists in this drive. Fire
and/or electrocution can result if caution is not exercised. Safety Warning, on pages 8 and
9, must be read and understood before proceeding.
