8.6 Setting the acceleration time and deceleration time
The acceleration time and deceleration time can be set so that an impact is not applied to a load when the motor is
started or stopped. There are the following two methods to set. The setting by the "acceleration/deceleration time
potentiometer" is enabled at the time of shipment.

z
Acceleration time
The acceleration time is set as the time needed for the motor to reach the rated
rotation speed (3000 r/min) from the standstill state.
z
Deceleration time
The deceleration time is set as the time needed for the motor to stop from the
rated rotation speed (3000 r/min).

Setting to the operation data with digital setting
When setting by the acceleration time and deceleration time of the data mode,
set the "analog acceleration/deceleration time" parameter of the parameter
mode to the digital setting.
For the acceleration time and deceleration time in this digital setting, set the
time needed to reach the set rotation speed.
Setting range: 0.1 to 15.0 sec (factory setting: 0.5 sec)

Motor operation
If the acceleration time and deceleration time are set shorter than
0.5 seconds, the motor takes for a longer time than 0.5 seconds to
reach the speed.
If they are set to approximately 0.5 seconds or more, the motor can accelerate
and decelerate in the setting time. (With no load)
When the frictional load or load inertia is increased, the operating
time to reach the setting will be longer.
