摘要 |
A control for a window operator is operable to control incremental movement of a window. The control includes means for developing a command to selectively move the window in a direction to an open or closed position, and means for determining when a plurality of motor drives have moved the window a preselected incremental distance. Means are coupled to the developing means and the determining means for energizing each of the motor drives if a command is developed, until the motor drives have moved the window the preselected incremental distance and thereafter deenergizing the motor drives until another command is received to move the window a subsequent incremental distance in the selected direction. |
