External DC voltage
External DC voltage is used when the speed is set from an external
control device.
For the external DC voltage, use a DC power supply (0 to 5 VDC, 1 mA or
more) with reinforced insulation on its primary and secondary sides.

VR1
The internal potentiometer VR1 is used when the rotation speed is
not changed frequently or is set without providing an external setting
device.
Adjust the potentiometer using an insulated screwdriver.

7.3 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 refers to a time needed for the motor to reach
3000 r/min from a standstill state.
The deceleration time refers to a time needed for the motor to stop from
the 3000 r/min.
The actual acceleration time and deceleration time vary depending
on the conditions of use, load inertia, or load torque specied by the
customer.
The setting range is 0.1 s to 15.0 s.
Factory setting: 0.1 s
