Control box D
This control box is fully configurable and controllable from a computer via RS232.
The list of new features is so long that it requires a specific page.
THE FRONT PANEL AND MANUAL CONTROLS:
On the front panel, in addition to the power button, there are two paddle buttons CW and CCW and the preset knob.
A few words about the preset:
It is made with a rotary encoder, allowing you to pre-set any direction in the 0-360 degree range by simply rotating the corresponding knob.
The moment the knob is rotated, the display automatically shows the preset position. Once the desired position is reached, by stopping the preset rotation, after 3 seconds the rotator automatically starts and the display returns to show the actual position of the rotator until the pre-set position is reached. In the 3 seconds between setting the preset and its execution, a new position can be changed or re-set. The preset command can be cancelled at any time by simply pressing one of the paddles for an instant.
FUNCTIONS AND PERFORMANCES:
(the list refers to the most important functions and is accompanied by a brief description)
Manually configurable and via RS232:
Stop North - Stop South (Stop South is default, can be changed with dip-switch or via software)
Soft Start and Soft Stop (Start and stop occur gradually with a 10-degree ramp. It can be included or excluded with the dip-switch or via software, the ramp can be programmed via software)
Rotation range 360° or 500° (selectable by dip-switch), 500° is the default value, in this case there are 70° of extra travel on both sides. The rotation range can be programmed by software, between 1° and 500° by re-setting the start and end values)
Functions configurable or programmable only via RS232:
Reverse delay (prevents immediate reversal of direction, 3 seconds default, programmable)
