6.5 Soft start/soft stop function
An impact on a load is suppressed by soft start/stop operation of the motor, and the motor starts running smoothly.
The acceleration time and deceleration time is xed to about 1 second at the time of shipment.
When adjusting the acceleration time and deceleration time, change the setting of the "acceleration/deceleration time"
parameter.
If this parameter is set to ON, the acceleration/deceleration time can be adjusted using the acceleration/deceleration time
potentiometer.
Setting range of the acceleration/deceleration time potentiometer: 0.1 to 15.0 seconds
The actual acceleration time and deceleration time against the setting vary depending on the load inertia and frictional load.

•
Acceleration time
The acceleration time is set as the time needed for the motor to reach
the 1000 r/min from the standstill state.
•
Deceleration time
The deceleration time is set as the time needed for the motor to stop from
the 1000 r/min.
If the deceleration time is set shorter than the time for coasting stop of the
motor, the motor will not stop at the specied time.

6.6 Limiting the setting range of the rotation speed
The setting range of the rotation speed using the setting dial can be limited by setting the upper limit and lower limit.

Speed setting range
•
Speed upper limit
The upper limit of the rotation speed can be set in the "speed upper limit" parameter.
If the rotation speed exceeding the speed upper limit is already set, the rotation speed set in the "speed upper limit"
parameter will be overwritten.
•
Speed lower limit
The lower limit of the rotation speed can be set in the "speed lower limit" parameter.
If the rotation speed below the speed lower limit is already set, the rotation speed set in the "speed lower limit" will be
overwritten.
