1. Rotation speed control by encoder sensor
The encoder sensor detects the main motor rotation. The main motor PCB Unit controls the number of main
motor rotations with the encoder sensor signal. The encoder sensor signal is transmitted to the main PCB
Unit as encoder dividing signal (8 dividings). The number of main motor rotations is checked with the
HELP01.
2. Selecting the Speed
The speed is selected with the main 1 - 4 on the main PCB Unit.
The following are the speed depending on the pin state.
: Slow 2 is applied to accelerating only. it is not used to reduce the speed. All the speeds
including slow 1 are accelerating speeds. if the slow 1 is not operated, all the other speeds
are not operated.
