Be sure to use a fuse or non-fuse breaker to protect the G3J. 2. Make sure that the interval between forward and reverse operations is at least 100 ms. 3. Be sure to apply the input signal of the G3F-S after the reversible contactor starts operating. If the input signal is applied before the contactor starts operating, the soft-start function may not operate. 8 G3J-S or G3J-T Three-phase, 200 to 220 VAC (380 to 400 VAC) Fuse or non-fuse breaker Forward rotation Reverse rotation Reversible contactor PLC relaysequential timer circuit G3J-T PLC relaysequential timer circuit 24 VDC Thermal overload relay 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. Forward rotation Reversible signal Reverse rotation G3J-T control signal Forward rotation Contactor control signal Reverse rotation Soft-stop time lag Soft-stop time lag 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. 9 ■ 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.

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. Soft-start/stop Characteristics Input ON Input OFF Input voltage 100% supply voltage 100% Starting torque Starting torque: 200% In to 450% In Supply voltage 0% Soft-start time (see note 1) Rated rotation speed Soft-stop time (see note 1) Rated rotation speed Rotation speed 0 rpm 0A Motor load current (The waveform will be deformed by the L of the motor.) α Rated current Ramp-up time: 1 to 25 s (See note 2) Ramp-down time: 1 to 25 s 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. 12 ■ Soft-start/stop Setting Method Adjuster 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. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937.
