Functional parameters of hfr1000 series soft start

Motor soft starter hfr1000 series function/parameter description

control mode selection (hf00), which can be directly controlled by panel keyboard or external terminal, and the factory value is 0

starting mode selection (hf01), there are three kinds: 0 voltage ramp starting, 1 current limiting starting, 2 sudden jump starting, and the factory value is 0

1. Voltage ramp starting

hf01 is set to 0, the starting ramp time t (hf07) is set, the torque lifting voltage (hf04) U0, the motor starts with the increase of input voltage, and the speed then rises to full speed. As shown in the figure

2. The current limiting starting

hf01 is set to 1, the starting current limiting percentage is (hf09) and the torque lifting voltage (hf04) are set, the motor current increases with the voltage ramp until is, the current does not increase, and the speed increases until the current drops below the rated current IE after full speed. As shown in the figure

3. Jump start

hf01 is set to 2, the start ramp time t (hf07) is set, the torque lifting voltage (hf04) u can automatically fold the printable expanded polymer material 0, the jump voltage percentage (hf05) and the jump time (hf06), the motor starts quickly with the sudden increase of input voltage, the voltage rises according to the ramp start mode, and the speed then rises to full speed. Suitable for starting large inertia load. As shown in the figure

starting delay time (hf02) is the preparatory starting time. During this time, the motor does not start, and the countdown display is adopted. This time can be set within 0 ~ 600s. And output - Dynamic make - Dynamic break contact signal, using this contact signal can generate a start alarm signal, reminding you to pay attention to safety! The factory value is 0s

there are two options for parking mode (hf03): 0 free parking, 1 soft parking, and the factory value is 0

free stop means that the soft starter directly drops from voltage ue to 0V, and the motor stops with inertia. As shown in the figure

figure jump start characteristic curve

figure free stop characteristic curve

soft stop is that the soft starter gradually decreases from voltage ue to 0V according to the slope decline time, and the motor stops directly as the voltage decreases and the speed decreases, which can prevent the water pump from producing "water hammer effect". As shown in the figure

torque increase (hf04), that is, adjust the torque generated by the initial voltage U0, and the factory value is 20%

for some loads with large static torque, a high voltage must be applied at an instant to produce a large torque before they can start smoothly. The regulation range of jump voltage (hf05) is 20% - 100% of the rated voltage, and the factory value is 50% of the rated voltage. Therefore, the metering and mixing system equipped must be within an appropriate flow range

jump time (hf06) is the time of applying high voltage, which can be adjusted within 1 ~ 60s, and the factory value is 2S

ramp rise time (hf07) is the time when the voltage rises from 0 to the rated voltage UE, and the factory value is 5S

ramp down time (hf08) is the time when the voltage drops from the rated voltage ue to 0, and the factory value is 5S

works when hf01 is set to 1, and the starting current (hf09) limit =hf09 × Ie, adjust hf09 so that the starting can be completed smoothly and the current is small and appropriate

this device is small in size. It can only be started after the temperature of the radiator drops every time it is started, otherwise it will be shut down due to overheating protection. The starting time interval (HF10) can be adjusted. It is appropriate to repeat full load starting no more than 10 times per hour, and the factory value is 60s

when the data is disordered, the factory value can be restored by setting the data initialization (hf11) to 1

fault storage 1 (hf12) stores and displays the current fault digital code, such as 0: no fault, 1: represents Oh over

thermal fault, 2: represents OC over-current fault, 3: represents pf phase failure, 4: represents ol overload or locked rotor fault

fault storage 2 (hf13) stores and displays the previous fault code, such as 0: no fault, 1: Oh overheating

fault, 2: OC overcurrent fault, 3: pf phase failure, 4: ol overload or locked rotor fault

fault storage 3 (hf14) stores and displays the fault code of the previous two times, such as 0: no fault, 1: Oh overheating

fault, 2: OC overcurrent fault, 3: pf phase failure, 4: ol overload or locked rotor fault

fault storage clearing (hf15) works when it is set to 0. Put the current fault code and the previous fault generation as shown in the photo, put the fixture and experimental piece into the thermostatic bath for experimental code, and clear all the previous two fault codes, which are displayed as 0. When hf15 is set to 1, the program will refresh automatically every time a fault occurs

the setting range of overload protection time (HF16) is 1 ~ 600s. When the continuous time of overload exceeds the setting time, the protection action and ol display can effectively protect the motor from long-term locked rotor and overload operation. The factory value is 60s

set the motor power (hf17) for current display deviation correction. The factory value is 22KW

when the quick start selection (hf18) is set to 1, when the motor speed reaches full speed, the voltage is quickly classified according to the force measuring method: mechanical force measuring experimental machine and electronic force measuring experimental machine; Speed up to full pressure to avoid motor vibration. When hf18 is set to 0, when the motor speed reaches full speed, the voltage still operates according to the preset ramp rise time

the setting range of the lower computer address (hf19) is 1 ~ 16. When controlled by the upper computer, up to 16 soft starters can be controlled. The address can be set in 1 ~ 16, and 255 is the broadcast address, which is valid for all machines

hf20 ~ hf21 functions are used for upper computer communication
