Options for PS1 series of the hottest motor soft s

The option of PS1 series of motor soft starter

PS1 device can only have the following control functions after selecting and adding the following options. These functions require additional control circuit boards

(I) option D - soft stop

this option extends the stop time during sudden unloading and can provide a smooth deceleration process. Adjusting the three settings can optimize the deceleration curve to meet the high standard control requirements

(1) the initial motor speed reduction is adjusted to eliminate the "dead zone" in the speed reduction process, allowing instantaneous power failure. When the voltage drops to a certain level, start to increase and reduce the speed voltage. The speed of the motor decelerates according to the decreasing voltage

(2) the set point of motor stop voltage is the point at which the deceleration voltage drops to zero

(3) the deceleration time is adjustable from 0 to 30s, and the adjustment time just falls at the stop voltage set point

the deceleration scheme is shown in the figure

1. Frequent start

the auxiliary control contact is located on tb4 on the deceleration circuit board. When the acceleration ramp ends, these contacts change state. When starting frequently, the deceleration state can be entered only after the end of the acceleration slope. If the time of frequent starting is too short, it will not enter the deceleration operation state. Two sets of C-type auxiliary contacts can be interlocked with other control functions. The rated power is 240V, 3a, 720W

2 Start

(1) confirm that the controller has been adjusted according to the requirements of PS1 manual

(2) confirm that the potentiometer on the reducer control board is set according to the following requirements

① start (P6) turn clockwise to the maximum position. ② Stop (P4) turn counterclockwise to the maximum position. ③ Time (P5) turns clockwise to the maximum position

(3) after the X6 or X7 jumper is inserted, the slope starts (see the position in the figure). When the jumper plug is unplugged, the motor will continue to operate. X6 and X7 plug positions represent two deceleration time ranges respectively. X7= short time (0.5 ~ 30s), x6= long time (30 ~ 60s), which depends on the load

(4) power on and adjust the controller as required before adjusting the deceleration shutdown. The adjustment should be carried out under normal load conditions

3. Deceleration adjustment

(1) unplug the X6 and X7 jumpers on the reducer and start the motor to run at full speed Then press the stop key and turn P6 counterclockwise until the motor slows down. There may be vibration during adjustment. Continue to adjust P6 counterclockwise until there is no vibration and the motor begins to decelerate as expected

(2) it is best to cut off the power before inserting the X6 or X7 jumper (if you should slow down in use, do not cut off the power, and quickly insert the jumper plug). When the X6 and X7 jumper plugs are inserted, the motor starts to slow down. When the motor is close to stopping, rotate P4 clockwise to adjust the stop voltage until the "decel on" indicator light goes out on the speed reduction plate. Try again to stop the motor and turn off the indicator light within the same time, otherwise try again as required

(3) rotate P5 counterclockwise to shorten the deceleration time

(II) option SR - impact protection relay

this overload protection is sometimes referred to as electronic fuse or quick trip, which can 2 The speed sensor ensures that the gap between the bottom of the sensor and the top of the engine tooth is 0.8 to 1.0mm, otherwise it will instigate misalignment, protect the motor from the danger of overload, and is widely used in transmission equipment. The SR option can monitor the motor current during startup and operation. When the current exceeds the set rated value, it will automatically turn off the power supply and shut down

the overload protection device is set with two overload protection ranges. The high range is used for the starting process of the motor, and the low range is used for the process after full speed operation. The high range can be adjusted between 200% and 1000% (P2). When the full speed is reached, the delay range can be adjusted between 1 ~ 10s (P1). However, some users often choose 3 meters when their experimental space is about 2 meters, and the model range can be adjusted between 50% and 200% (P3), Adjust the time of tripping delay (P4) from 0.25 to 3S. This tripping sensitivity time can prevent misoperation when detecting overload

for some motor driven equipment (such as crusher) used for processing materials, the motor will stop after wiring according to SR option. Please contact the manufacturer for wiring information

1. Adjustment steps of impact relay

figure reduction circuit board

(1) clockwise adjust the potentiometer on the impact relay protection board to the maximum value

(2) adjust the starting device as required

(3) after the starting device is adjusted, stop the motor and then adjust the tripping range

the protection board of impulse relay is shown in the figure

2. The setting of high current trip range (P2)

rotate the high current trip potentiometer (P2) for 1/4 turn. The correction range of this potentiometer is from 200% to 1000% full load current ratio. Start the motor under normal load conditions. If the controller trips, proceed to the next step (2). If it does not trip, proceed according to (1) below

(1) stop the whole system, turn up the trip potentiometer in the counterclockwise direction, restart it, and then carry out (2) adjustment steps until there is a trip

(2) fine adjust the high range trip potentiometer clockwise, and then start it. If the motor does not trip, it means it has been adjusted. If there are periodic trips during operation, adjust the high range trip potentiometer clockwise under load

3. Time delay adjustment at full speed (P1)

the low range trip point of the motor at full speed can adjust the time delay trip to achieve it quickly. By adjusting P1, the time delay can be adjusted between 0 ~ 10s. Once the full speed is reached, the time of entering the low range trip can be obtained by adjusting P1

4. Low range trip adjustment (P3)

when the motor operates under normal load, adjust the low range trip potentiometer counterclockwise until it trips, and then adjust it clockwise until the motor just starts to operate. If the equipment has higher current regularly, the trip delay should allow these higher currents to pass. The adjustment range is from 50% to 200% of the rated working current

5. Trip time delay adjustment (P4)

trip time delay adjustment during low range operation can eliminate misoperation

6. Trip status reset

figure impact relay protection board

disconnecting and connecting the control power supply or opening the dynamic breaking contact on TB2 for a short time can reset the trip, and the equipment must be reset before normal operation

7. The output signal

tb3 has a group of C-type contacts with rated power of 240V and 3a. They act in the tripping state and can be connected to an interlocking contact on the control board (tcb2000) or to the control circuit of other motors according to the application

8. Indicator sign

figure the luminous indicator installed on the dual slope circuit board

circuit board indicates the following states:

(1) e recent or - the slope ends, and the start delay changes from high range to low range

(2) low - low range trip

(3) high - high range trip

(4) fault - tripping occurs

(III) option AA - dual ramp

dual ramp mode can provide two independent torques and ramp mode, which is suitable for two speed motors, motor reverse control and frequent starting conditions. The dual ramp component is a small circuit board installed on the upper part of the main circuit board. The potentiometer is adjusted as follows: p1= current limiting, p2= ramp time, p3= initial torque, x1= ramp starting (the same function as X5 on the main board). Adjust slope 1 (P2 potentiometer on the main board). To select slope 2 (P2 on the additional AA board), close the dynamic contact of 1 and 2 contacts of Tb3 on the AA board. To adjust slope 2 (P1 on the AA board), adjust the potentiometer on the additional AA board according to the figure
