8.7 - Motor Controls

There are several motor processes that can be completed using the debug interface.

It is sometime necessary to move the system during troubleshooting. The proper

precautions must be taken when moving the system through the debug interface.

Caution: There are several safety features which are disabled during some commands

such as the motor stall timer and azimuth-skew lock out. Make sure the system can

move in all axis and unintended movements will not damage the antenna or

surrounding structures. Make sure the antenna is raised to a safe elevation before

moving the azimuth or skew motors. The MOTOR commands require a minimum

elevation before the other axis can be rotated. This is not the case for velocity

commands (DC). Stay clear of the system during all system movements. Typing “s” and

pressing enter at any time from the debug menus MOTOR>, DC>, and HOME> will stop

all motors.

There are 3 major types of motor commands. Each is described below.

8.7.1 - Angular Movement

The first type of movement is an angular movement command that is done from the

“MOTOR>” menu. Movements are given using angular commands. Below is an excerpt

of what you will see in the debug screen. The “motor” command was issued from the

“TRK” prompt and the “a” command (angle) displays the current motor angles.

Important Note: Typing “s” and pressing enter at any time stops all motors.

MOTOR>s

AZ stopped.

EL stopped.

SK stopped.

MOTOR>

TRK>motor

MOTOR>a

AZ = 355.93° wrap = -4.07°

EL = 29.52°

SK = 325.64°

MOTOR>

Each motor is identified by a number. The azimuth is motor 0, the elevation is motor 1,

and the skew is motor 2. The format for a motor movement command is “a [motor#]

[angle].
