Motor
For soft-stop control, the G3J-T has enough load current to continue rotating the motor during ramp-down time setting even after the control signal
of the G3J-T is tuned OFF. Therefore, a time lag is required between the time when the G3J-T stops operating up to the time when the reversible
contactor is turned OFF. The ramp-down time of the G3J-T is adjustable up to approximately 25 s max. Therefore, set the time lag to 25 s in the
initial sequence during the adjustment stage. Adjust the time lag of the sequential circuit according to the application.

Note: Make sure that the interval between forward and reverse operations is at least 100 ms. If the G3J is turned ON by noise input, short-circuiting
between phases will result. In order to prevent this, insert a protective resistor.
!WARNING
Do not use two G3J-S or G3J-T Units together in reversible operation.

■ Connections Example
Harmonized protection is ensured for motor overcurrents.
Be sure to supply power to the G3J through a fuse or non-fuse breaker to protect the G3J from damage due to short-circuiting.

When selecting a fuse to protect a G3J, use a quick-breaking fuse for semiconductor protection that satisfies the following condition:
fuse’s I2t < G3J’s I2t.

Operation
■ Soft-Start/Stop (Function of G3J-T)
The G3J-T is a solid state contactor that smoothly starts and stops
machines and equipment connected to power supplies without
damaging the machines, equipment, or power supplies.
Soft-start Time
The voltage imposed on the motor increases while ignition α is
gradually reduced, thus gradually increasing the rotation speed of
the motor.
Ramp-up Time
Ramp-up time is a period required for ignition α to become zero
degrees with a 100% voltage imposed on the motor.
Starting Torque
Starting torque is determined by the value of ignition α immediately
after the input signal is turned ON.
Soft-stop Time
The voltage imposed on the motor decreases while ignition α is
gradually increased, thus gradually decreasing the rotation speed of
the motor.
Ramp-down Time
Ramp-down time is a period required for ignition α to become
180 degrees with a 0% voltage imposed on the motor.

Note: 1. In addition to starting torque, ramp-up time, and ramp-down time, the soft-start time and soft-stop time vary with the load characteristics
such as the inertia and friction factor of the load. Therefore, the soft-start time or soft-stop time will not increase beyond a certain point.
2. Due to the soft-stop control characteristics, the load current continues flowing even after the motor stops. Set to the optimum value
according to the adjustment steps.

■ Soft-start/stop Setting Method

Adjustment Steps
Starting Torque Setting with the Starting
Torque Adjuster
The starting torque of a motor can be set within a range from 200%
to 450% In provided that the starting torque is 600% In when the
motor is started at full voltage, which allows optimum motor control
without any time lag at the time the motor starts.
200%
450%
INITIAL
TORQUE
Set with a Phillips or
flat-blade screwdriver.
Ramp-up Time Setting with the Ramp-up
Adjuster
The ramp-up time of a motor can be set within a range from 1 to 25 s,
with which the soft-start time of the motor is adjusted until the motor
rotates at full speed.
RAMP
UP
1. Start and stop the motor with the factory settings.
Ramp-up adjuster: 1 s
Starting torque adjuster: 200% In
Ramp-down adjuster: 1 s
2. If the motor does not rotate smoothly, increase the starting torque.
3. Gradually increase the ramp-up time to adjust the start time.
4. Gradually increase the ramp-down time to adjust the stop time.
5. The soft-start time or soft-stop time will not increase beyond a
certain point (depend on load). Do not set the ramp-up time or
ramp-down time beyond this point.
Further Adjustment or Arrangement
1. Increase the starting torque if the motor does not start with a long
soft-start time.
2. To start normally (i.e., not using soft-start) use a simple G3J
model.
Set with a Phillips or
flat-blade screwdriver.
Ramp-down Time Setting with the Rampdown Adjuster
The ramp-down time of a motor can be set within a range from 1 to
25 s, with which the soft-stop time of the motor is adjusted until the
motor decelerates to a stop.
RAMP
DOWN
Set with a Phillips or
flat-blade screwdriver.
