- Ejection Operation
1. When the OPEN/CLOSE key is pressed or when the
ACC is turned ON, the motor is driven in a high-
speed mode.
2. The motor is driven in a low-speed mode, when the
DEG0SW is switched from L to H.
3. The counting of angular pulses starts from a point
where the DEG0SW is switched from L to H, and the
motor will stop when 52 edges (100 degrees), of the
angular pulse is counted (brake mode).
If a previous angle has been stored in the memory
however, the motor will continue to operate until
that angle has been attained. 54 edges (100 degrees)
or the position stored in the memory
- Retraction Operation
1. The motor is driven in a low-speed mode when the
OPEN/CLOSE key is pressed or after six seconds
when an ACC OFF state is attained (when the
automatic ejection and retraction setting is set to
ON).
2. The motor is driven in a high-speed mode when the
DEG0SW switches from H to L. The motor operation
is brought to a halt when the angular pulse cannot
be detected for a period of 500 ms (brake mode).
