TACH VOLT
SENSE
(Tachometer Voltage Sense)
Sets the minimum armature voltage where
the Encoder Loss and Reverse Tach
functions will become operative. This
parameter prevents nuisance encoder faults
during low speeds and high torque
conditions by adjusting the encoder loss
sensitivity to motor IR drop. Works in
conjunction with TACH SPEED SENSE. An
ENCODER FLT will be declared if the
following two equalities are satisfied:

(Tachometer Speed Sense)
Sets the level of measured speed feedback
below which an Encoder Loss Fault is
declared – once motor armature voltage
conditions are satisfied. Works in conjunction
with TACH VOLT SENSE. An ENCODER

OVLD START
LEVEL
(Motor Overload Start Level)
This parameter defines maximum current at
which motor can run continuously without
triggering the motor overload. One of the
two parameters that define the motor
overload curve. Set as a percent of Rated
Motor Current. For more information on the
motor overload curve, see OVLD TIME OUT
and OVLD START LEVEL on page 62.
