3.5 Potentiometers -Adjustments
The following is a description of the function of each pot. The pot settings can be measured at
test points TP1 thru TP7.
Potentiometer Description
SIGNAL
The signal potentiometer is used for scaling the command signal.
Turning the potentiometer CW increases the amount of command
signal to the front end of the amplifier.
TACH
The tachometer potentiometer is used for scaling the various
tachometer voltage gradients. This input has to be used because
of special signal conditioning. Turning the pot CW increases the
amount of tach-feedback into the amplifier.
COMPENSATION
The Compensation potentiometer is used to increase or decrease
the response (bandwidth) of the amplifier. Turning the
potentiometer CW increases the response of the amplifier.
PEAK CURR LIMIT
The peak current limit potentiometer is used to increase or
decrease the peak output current of the amplifier. Turning the
potentiometer CW increases the output current of the amplifier
from zero amps to maximum peak amps.
BALANCE
The balance potentiometer is used to stop motor rotation when no
input signal exists. The function of this pot is such that for zero
input volts the output current should be at zero amps.
RMS
The RMS potentiometer is for changing the level of the RMS
current. The amplifier is capable of providing maximum RMS
current when fully CW. The minimum current is approximately 0
amps when fully CCW.
