Example of Operational Timing Chart
The following chart shows an example in which speed is switched between two levels, with the external speed potentiometer
set to 1000 r/min, and the internal speed potentiometer set to 3000 r/min.

The switch numbers shown in the timing chart (e.g. SW2) correspond to SW1−4 in the connection diagram on page 10-11.
Note To run or stop the motor, do not turn power on or off. Instead use the CW or CCW input.
