4. When making settings for "setback ON", after the
angle has reached to the prescribed position by the
movement according to the above Paragraph 3,
move the position motor toward the storing direction
at a low speed after waiting for about a second.
When the motor returns, it will be stop mechanically
and braking movement will be activated by the error
timer or by the effective edge of he angular encoder.
- Storage operation
1. Operating the CLOSE key (or, when the automatic
open-close setting is being turned ON, 6 seconds
after turning OFF the ACC), move the position motor
forward at the low speed until the LIFT switch is
turned OFF.
2. When the LIFT switch has been turned OFF, stop the
position motor and move the angle motor at a low
speed.
3. When the angular direction SENSE switch (Angle "0"
degree switch) is turned ON and when the angle
pulse has disappeared, stop the angle motor and
move the position motor at high speed.
mechanical contact is made and the storage move-
ments have been completed, the movement will stop
by the function of the error timer.
- Angular adjustment
1. If, for example, the UP key is pressed from the initial
position (about 90 degrees), move the position motor
at high speed as far as the tip end. One second after
the forward and backward pulses disappear, move
the angle motor under the low speed mode for the
equivalence of 1-wave of the angular pulse before
going into the braking mode.
2. Then, after about 3 seconds from the above state,
move the position motor at low speed to stop (brak-
ing mode) at the point where the forward and back-
ward pulses disappear.
when DOWN key is pressed.
