7.1 Input signals and output signals
Caution
Do not perform the motor’s starting and stopping operations by
turning the power supply on and off. Perform them by inputting
START/STOP and RUN/BRAKE. This may cause injury or
damage to the equipment.
Note
• The input signals (START/STOP, RUN/BRAKE, CW/CCW, INT.VR/ EXT,
ALARM-RESET) must be ON for at least 10 ms. It may cause malfunction of
the motor.
• Do not operate (switch the ON/OFF status) of the START/STOP input,
RUN/BRAKE input, CW/CCW input and INT.VR/EXT input simultaneously.
After switching a given input, wait at least 10 ms before switching another
input.
• The motor temperature rise is sharper as friction load and inertial load are
higher, and start, instantaneous stop and reversing frequency is higher. It
must be used when motor case temperature does not exceed 90 °C
(194 °F), and driver heat radiation plate temperature does not exceed 90 °C
(194 °F).
START/STOP input and RUN/BRAKE input
To switch between motor running and instantaneous stop (or stop), use
START/STOP input, RUN/BRAKE input.

∗1 The motor speed can be made to reach the set speed by any one of the internal
potentiometer, external potentiometer or external DC voltage.
The motor accelerates over the time set by the acceleration/deceleration time potentiometer.
∗2 The motor decelerates over the time set by the acceleration/deceleration time potentiometer.
Note
• The BRAKE takes precedence when START/STOP and RUN/BRAKE inputs
are turned off simultaneously.
• The actual acceleration/deceleration time is affected by the use condition,
load inertia, load torque and other conditions implemented by the user.
START/STOP input
START is selected when the input is ON, and motor starts running. The motor
accelerates over the time set by the acceleration/deceleration time potentiometer.
STOP is selected when the input is OFF, and motor stops. The motor decelerates
over the time set by the acceleration/deceleration time potentiometer.
