12.11.2 DC Stepping-Motor operation
Caution: All the louver angles or louver positions mentioned in this specification are
the rotation angles of the stepping motors. They are NOT necessary equal
to the rotation angles of the louvers.

Note:
1. The Motor Direction is defined to be the rotation direction (Clockwise | Anticlockwise) when the
louver is closing. (Viewed from the top of the motor.)
2. The Auto_Swg_Limit of WMF is 60-60
o
. Therefore, its Auto-swing operation is disabled, and
the louver will only stay at the 60
o
position. The louver position reset (Cf.: 10.2.1 (x)) would
be disabled in this case, to prevent unnecessary louver movement.
3. The Max_Swg angle is an independent mechanical angle (by the step motor taking into
account the gears transmission) of the product (ROM value).
4. Travel at Auto Swing angles are 4 independent parameters set under this mode (EEPROM
values).
5. The user angles are the same as the cooling Auto Swing Angles.
6. For LockAngle, refer to the rule from Operation to STBY.
1.General Operations of Louvers driven by DC Stepping Motor
(i) The louver position is defined by the angular position of the stepping motor. When
the louver is completely closed, the motor position is defined to be 0
o
. When the
louver is completely opened, the motor position is defined to be the Total Angle
(Max_Swg).
(ii) Max Swg of the motors are model dependent as shown in the table above.
(iii) If the louver is in Auto-swing mode, it would move to-and-fro continuously within the
Auto_Swg_Limit except the 1st swing cycle (see (iv) below). Both the upper and
lower limits are determined by the type of models and current operating mode as
shown in the table above.
(iv) When a step motor start to operate in Auto-swing mode, the motor will move between
the User_Swg_Limit during the 1st swing cycle. The purpose of this operation is to let
the user set the “louver user position” by using only the swing button (e.g. the Vertical
Swing Button in RC-4). In the following cycles, the motor will move between the
Auto_Swg_Limit.
