Operation
7.2 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 starts
or stops.
The acceleration time is set as a time needed for the motor to reach the
rated rotation speed from a standstill state. The deceleration time is set as
a time needed for the motor to stop from the rated rotation speed.
The actual acceleration time and deceleration time are aected by
customer's conditions of use, load inertia, and load torque.
The setting range is 0.1 s to 12.0 s.
Factory setting: 0.1 s

7.3 Operation and stop
Use the START/STOP input and the RUN/BRAKE input to operate or stop the motor.

Signal level
ON ON Operation
ON OFF Instantaneous stop
OFF ON Deceleration stop
If the RUN/BRAKE input is turned OFF during deceleration stop, the motor stops instantaneously.
Deceleration stop: The motor decelerates to a stop according to a time set in the deceleration time.
Instantaneous stop: The motor stops at the shortest time without following the deceleration time.
START/STOP input, RUN/BRAKE input
The motor rotates when both the START/STOP input and the RUN/BRAKE input are turned ON.
If the START/STOP input is turned OFF while the motor rotates, the motor decelerates to a stop according to the setting
of the VR2.
If the RUN/BRAKE input is turned OFF while the motor rotates, the motor stops at the shortest time (instantaneous stop).
FWD/REV input
This is a signal to change the motor rotation direction. The motor rotates in the CW direction when this signal is turned
ON, and in the CCW direction when it is turned OFF.
Note
•
When the START/STOP input and the RUN/BRAKE input are turned OFF simultaneously, the RUN/BRAKE input is
prioritized.
•
The actual acceleration time and deceleration time are aected by customer's conditions of use, load inertia, and
load torque.
