- Angular adjustments
1. When the UP key is pressed, the monitor is raised
from its initial position (100 degrees), and will
continue to rise until the key is released. The
A
operation will stop one pulse after the release of the
UP key.
2. The DOWN key operation results in similar motions.
- Protective Operation
1. During the horizontal ejection of the monitor, when
the angular pulse cannot be detected for a period of
500ms, the retraction operation will be triggered.
DOWN
2. During the startup (or angling down) of the motor,
when the angular pulse cannot be detected for a
period of 500ms, the brake mode will be triggered.
B
3. During the horizontal retraction of the monitor, when
the angular pulse cannot be detected for a period of
500ms, the brake mode will be triggered.
4. During the ejection or retraction of the monitor, when
the angular pulse is detected for a period of more than
20 sec., the brake mode will be triggered.
- DISPLAY SECTION MECHANICAL OPERATION
SPECIFICATION
During horizontal operation: 68msec.
When start-up operation: 191msec.
- Direction of rotation
Forward rotation (ejection):DEGPUL124681012
The phase of DEGPUL1 advances by 90 degrees.
1DEGPUL235791113CountingC
of edges
Reverse rotation (retraction)
Phase difference: 90o degrees
The phase of DEGPUL1 loses by 90 degrees.
For forward rotation
- Cautions
1. The angular position is continuously incremented,
with the last position stored in the memory for useAngular pulse
when the system is turned on again.
However, when the display is forcibly moved by the
hand etc. ,the position is not memorized.14msec+200?sec
2. If a specified pulse is not detected during an
operation, it is determined that an operational
abnormality exists, and the operation will be halted
at that point.
3. The brake operation is performed at 14ms + 200ms
(? time required for monitoring the chattering) after
D
the prescribed L angular pulses are detected.
