Parameter setting procedure 31

General sensor is in current type the wiring method of spd is similar to pressure transmitter connected to ai terminal as pressure feedback if voltage sensor is use please modify p0 4 to 0 the wiring method of spd is similar to transmissible pressure gauge connected to ai terminal as pressure feedback 33

Note because working voltage of sensor is different before using set working power source of the sensor by p0 5 besides make sure test result is precise set range of the sensor p0 3 according to sensor parameters 33

P0 0 is the pressure value of the pipe network if p0 0 3 bar after the smart pump drive is started the pressure of the pipe network keeps constant at 3 bar 33

P0 3 is the range of the sensor common range is 1mpa namely 10 bar 33

Programming description of parameters 33

When feedback value is smaller than or equal to set pressure minus pid start pressure p0 0 p0 1 and it holds the state in p0 0 set time pid adjustment will be restarted for example when p0 0 3 p0 1 0 p0 0 5 if feedback value is smaller than or equal to 2 and the time is longer than 5s pid adjustment will be restarted once it is larger than 2 the time will recount 33

Adjustment method 34

If factory parameters can t meet demands adjust parameters finely first increase proportional gain to make sure that the system will not oscillate 34

In initial use confirm the rotation direction of motor exchange arbitrary two lines of output power line u v w of the spd or modify parameter p0 2 to change the rotation direction of the motor 34

Note improper parameter setting of p0 6 will cause huge speed overshoot and even over voltage fault in overshoot back 34

After selecting sleep mode 1 by parameter p0 8 the spd will detect whether feedback pressure is higher than set pressure if yes the spd will start sleep detection after pid sleep detection delay set by p0 9 if feedback pressure is still higher than set pressure spd will decrease output frequency gradually to sleep detection low level hold frequency set by p0 1 after sleep detection low level hold frequency waiting time if feedback pressure is still higher than set pressure the spd decreases output frequency to 0hz and enter standby if in above process feedback pressure is lower than set pressure the spd will judge as invalid sleep detection and come back to pid adjustment status 35

After the spd enters standby if feedback pressure is lower than pid sleep threshold spd will start wakeup detection after pid wakeup detection delay set by p0 0 if feedback pressure is still lower than wakeup pressure threshold wakeup is successful and spd comes back to pid adjustment status else wakeup fails too high pid sleep threshold may cause frequent start and stop of the spd too low pid sleep threshold may cause deficient pressure 35

Notes sleep holding frequency of different water supply system is different when there is no water outside and the water tap is turned off but the pump is still running increase p0 1 to sleep holding frequency 35

When sleep mode 2 is selected the system will try to sleep according to water consumption condition automatically 35

Anti freezing frequency can t be set to high it should be set as the frequency that can just drive the pump but can t supply pressure 36

If you hope that the spd can start automatically after time delay set by p0 5 at power on after setting all parameters make p0 4 11 to enable auto start function of the spd every time at power on or fault reset it will start automatically 36

In no water consumption because of water leakage of pipe network the spd can t sleep and stop it starts and stops frequently to solve the water leakage problem of pipe network modify the value of p0 0 according to water leakage the bigger the water leakage the bigger the coefficient 36

Pump auto adjusting given frequency is prior to anti freezing frequency 36

Set p0 6 1 to enable anti freezing function the spd will adjust the running frequency of pump according to current status after it is started 36

The spd will compare p0 1 and p0 3 according pipe network pressure fed back by sensor if pressure is abnormal it will stop and alarm automatically to protect pipe network system 37

Acceleration deceleration time setting of the pump s moto 39

After setting parameters if you don t want them to be modified by misoperation make p0 9 1 at this time parameters can only be monitored but not be modified only when p0 9 is modified to 0 can parameters be modified 39

If you find there is some deviation between sensor feedback pressure and feedback pressure displayed on spd adjust above parameter to correct the sensor note the unit of current sensor is 4 20ma that of voltage sensor is 0 10v 39

Record fault type of the spd 0 means no fault 1 29 refers to e001 e029 for more details please refer to fault inspection and troubleshooting chapter 39

When p0 8 is set as 1 restore factory default 39

Each spd can choose different start stop modes and frequency sources 40

If use a 60hz pump please set parameters according to the following steps 40

P1 6 limits the maximum working frequency of spd 40

P1 group parameters have the same meaning as p0 group please refer to p0 group for more details 40

Step 1 set the parameter p1 6 upper limit frequency to 60 40

Step 2 set the parameter p1 3 motor rated frequency to 60 40

Use p1 8 to choose running status of spd when running frequency is lower than lower limit frequency to prevent motor from being in low speed operation for a long time you can use this parameter to stop it 40

Use this parameter to adjust carrier frequency of spd you can decrease motor noise by adjusting carrier frequency avoid point of resonance decrease leakage current of wires to ground and decrease interference of spd 40

When carrier frequency is high motor loss decreases temperature rising of motor is small but spd loss increases temperature rising of spd increases and interference increases 40

Feedback broken line detection value the detection value is relative to input signal voltage system keeps detecting pid feedback value when feedback value is smaller than or equal to feedback broken line detection system starts detection timing when detection timing exceeds feedback broken line detection time system will report pid feedback broken line fault 41

Please set according to parameters of the motor nameplate 41

To guarantee control performance please configure motor according to standard adaptive motor of drives if there is big difference between motor power and standard adaptive motor control performance of drives will decrease obviously 41
