Second, deceleration time at stop is set to 2.5 to 3 seconds.
Therefore, the frequency is 0 to 50 / 60H when the motor is started.
The time to reach Z becomes 3 seconds (same as when stopped), and the voltage also increases and decreases in proportion to the frequency. By setting the time in this way, the wheel (5) does not slip due to the motor starting torque when the truck starts, and the wheel (5) does not slip due to the brake when stopping. Even if there is a gap between the actual traveling distance and the distance measured by the position detection sensor (22), when the dust remover (1) returns to the start position, that is, the origin, the limit switch (31) operates to detect the position. Since a 0-point return signal is input to the unit (28) and 0-point correction is performed, no trouble occurs.
