Operating the Motor
(1) Mode Table for Signal Input
(2) CW and CCW Operation
When CW or CCW input is turned on (switched to low), the motor accelerates to the selected speed for the length of time
set on the acceleration time potentiometer. If CW and CCW are input simultaneously, CW has priority. Thus, if CCW input
is left on, direction can be changed instantaneously by turning the CW input on and off. However, under certain power
supply voltages or load conditions, change of direction may be delayed.
Note
When the motor is operated with the gearhead attached, the gearhead's output shaft may, depending on the
gear ratio, turn in the opposite direction of the motor shaft.
See the operating manual of gearhead for information concerning the direction of rotation of the gearhead output
shaft.
Use a insulated miniature screw driver for adjusting the Accelaration time potentiometer and the deceleration time
potentiometer.
(3) Instantaneous Stop and Deceleration to a Stop
■
Instantaneous Stop
To stop the motor instantly, turn SLOW DOWN input off (switch to high).
■
Deceleration (and stop)
When SLOW DOWN input is turned on (switched to low), the
motor decelerates for the length of time set on the deceleration
time potentiometer and comes to a stop.
The acceleration/deceleration time is set using the time
potentiometers on the front panel of the driver. The time of
acceleration/deceleration is lengthened by turning the
potentiometer clockwise. In addition, the motor can be stopped
instantly if SLOW DOWN input is turned off (switched to high)
during deceleration.
(4) Changing Speeds
Speed can be changed by selecting the external speed potentiometer or the built-in speed potentiometer by means of signal
input to EXT.VR. (speed selection input) as given in the table below. Speed can be changed while the motor is running.
The rate of acceleration/deceleration depends on the time set for acceleration/deceleration.
