Rotation direction of the motor output shaft
The rotation direction of the motor output shaft represents the direction when viewed from the motor output shaft.
The rotation direction of the motor can be changed using the "Motor rotation direction selection" parameter of the
MEXE02
or
OPX-2A
.

Combination type-parallel shaft gearhead
The rotation direction of the gearhead output shaft may vary with that of
the motor output shaft depending on the gear ratio of the gearhead.

Combination type-hollow shaft at gearhead
For all gear ratios, the output shaft of the gearhead rotates in the opposite direction to that of the motor.
The direction is dierent depending on whether the pre-assembled motor/gearhead is viewed from the front side or
rear side.

8.3 Setting the acceleration time and deceleration time
The acceleration time and deceleration time when starting and stopping the motor can be set. The acceleration time
and deceleration time are eective for all speed setting devices. The acceleration time and deceleration time are the
same value. They cannot be set individually.
The acceleration time and deceleration time can be set using the acceleration/deceleration time potentiometer (VR2).
Turning the potentiometer clockwise increases the time.
The acceleration time refers to the time needed for the motor to reach the rated speed (3000 r/min) from the standstill
state.
The deceleration time refers to the time needed for the motor to stop from the rated speed (3000 r/min).
Setting range: 0.2 to 15 seconds
Factory setting: 0.2 seconds

The actual acceleration time and deceleration time vary depending on the conditions of use, load inertia, load torque,
etc.
If smooth acceleration operation or deceleration operation cannot be performed, increase the acceleration time and
deceleration time.
