Deadband (DB)
The DB setting determines the time that will elapse between the
application of current in one direction before current is applied in the
opposite direction.
The DB affects the resistance that a motor has to changes in the shaft
position at zero speed. It does this by applying an AC voltage to the
motor armature.
The deadband is factory calibrated to approximately 3/4 of a turn
position for 60 Hz AC line operation. Recalibrate the trim pot to
approximately the 1/4 of a turn position for 50 Hz AC line operation. If
you hear motor noise (humming), the deadband might be set too high.
Turn the DB trim pot CCW until the motor noise ceases.
