1 | OBJECT: 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. |
