GETTING STARTED
To install the amplifier you will require a control, or reference, voltage, a power
supply, and a load. The reference voltage can be as simple as a potentiometer, or as
complex as a digital control system. First you must determine the mode of operation,
and the connect the amplifier to power supply, load and control system. Once
installed, you will next power up and check that the motor, tachometer and control
signal polarities are correct. The final operation is tuning, the process of adjusting
amplifier gain, control system parameters, etc. to achieve the desired performance of
the system.
OPERATING MODES
A mode is simply the way that the amplifier is used. Because the amplifier is one of
the several components comprising a system, the operating mode frequently depends
on the other components in the system. A tachometer is the most important option in
determining the operating mode. If you use a tachometer, the amplifier will be
