1OBJECT:  Drive
2  DESCRIPTION:
3    This object provides an interface to the elevation/azimuth
4    drive system(ECA). 
5  THEORY OF OPERATION:
6    This object encapsulates the turret drive.  The object provides
7    an interface to control the turret drive.  A method is provided
8    to set the azimuth and elevation rate of the drive.  Methods are
9    provided to request the drive to run in stabilized or power mode
10    and set the drive speed to high or low.  A method is also provided
11    to allow for drift adjust. 
12
13    This object also tracks drive system on hours.  It gets the hours
14    from the EEPROM data, allows the hours to be set, updates the
15    hours via the activation and deactivation of the drive, and
16    provides access to the hours.
17
18    The object also provides methods to access azimuth and elevation
19    displacement, and methods to process changes in the hardware
20    discretes drive on, stabilized mode, thermal fault and fault.
21 
22    The object also provides methods to enable and disable
23    both the remote and turret power interlocks which determine if
24    the drive can be driven by the remote or turret handstation
25    respectively.
