Connection Of The Main Circuit And The Grounding Terminal
(I) Main circuit power input terminal (R,S, T)
a.Connect the main circuit input terminals R, S, T to the three-phase AC power through the circuit breaker for circuit protection or circuit breaker with leakage protection without considering the connection sequence
b.Do not use ON/OFF of the main circuit power to control running and stop of the soft starter, instead, such should be controlled by means of the control terminal or RUN and STOP buttons in the keyboard panel of the soft starter upon power on.
c.Do not connect the soft starter to the single-phase power.
(2) Output terminals of the soft starter (U ,V ,W )
a.Output terminals of the soft starter should be connected to the three-phase motor in correct phase sequence. If the rotation direction of the motor is incorrect, switch connection of any two phases among U, V and W.
b.The output end of the soft starter shall not be connected to capacitor or surge absorber.
c.If the wire between the soft starter and the motor is very long, the distributed capacitance between the wires will generate highfrequency current which may cause over-current tripping, leakage current increasing and poor current display precision of the soft starter. Therefore, it is suggested that the motor connection wire should be no more than 50m.
(3) Grounding terminal of the soft starter (〨 G)
a.For safety and noise reducing, the grounding terminal G of the soft starter must be well-grounded. To prevent electric shock and fire accidents, the metal enclosure and frame of the electric equipment should comply with the requirements of the national electronic procedures.
Starting Mode
Current limiting starting mode
a)The soft starter will be under current starting mode when code F9 is set to O (current limiting). Figure shows the current change wave of the motor under the current limiting mode. 11 is the set starting current limiting value, when the motor starts, the output voltage will increase rapidly until the current of the motor reaches the set current limiting value 11, and the current of the motor will be kept under such value, then with the increasing of the output voltage, the motor will speed up gradually, and when the motor reaches the rated rotation speed, the bypass contact will close, the output current will drop rapidly to the rated current IE of the motor or less, and the whole starting process completes.
b)When the load of the motor is relatively light or the set current limiting value is relatively high, it will be normal that the maximum current may not reach the set current limiting value. Generally, current limiting starting mode applies to the occasions where there're strict limiting requirements on starting current.
Voltage Ramp Starting
a)The soft starter will be under voltage starting mode when code F9 is set to I (voltage). Figure 12-2-1 shows the output voltage wave of the output ramp starting. UI is the starting voltage value at start, when the motor starts, if the current of the motor is within the range of the rated value 400%, the output voltage of the soft starter will increase to UI rapidly, then the starting parameter set according to the output voltage will rise gradually, and the motor will accelerate smoothly with the rising of the voltage and reach the rated rotation speed when the voltage reaches the rated voltage Ue, then the bypass contactor will close and the whole starting process completes.
b)Starting time: t is the control parameter calculated from the standard testing condition based on standard load. Taking this parameter as the criteria, thePRS 3000 series soft starter enables the motor accelerates smoothly through controlling the output voltage to complete the starting process. This parameter is not the mechanical control time t which has nothing to do with if the motor accelerates smoothly or not. Given this, when the load is relatively light, the starting time will be less than the set starting time, and it will be normal as long as the starting process completes smoothly. Generally, the voltage ramp starting mode applies to the occasions where high requirements are not placed in the starting current but in the starting smoothness.
Kick Mode
a)The soft starter will be under kick starting mode when code F9 is set to 2(kick+ current limiting) or 3(kick + voltage). Figure 12-3-1 and 12-3-2 show the output change wave of the kick starting mode. In some occasions with heavy load, this starting mode can be used when the motor fails to be started due to effect of the mechanical static friction force. During start, apply a relatively high fixed voltage to the motor for a limited period to overcome the static friction force of the motor load to rotate the motor, then the motor will be started in the current limiting or fixed voltage ramp method.
b)Before using this mode, the motor shall be started through the non-kick mode, and this mode shall be only used when the motor fails to rotate due to high friction, otherwise, starting with this mode shall not be used to reduce the unnecessary shock caused by large current.
Current Ramp Starting Mode
a)The motor will be under current starting mode when code F9 is set to 4(current ramp). Figure 12-4-1 shows the output current wave of the current ramp starting mode, I 1 is the time value set by code F 1.
b)The current ramp starting mode possesses strong accelerating capacity, when used in bipolar motor, it can shorten the starting time to a certain extent.
