RS485 - Industrial Instrumentation Parts

Part List

Used to start,stop pump and for reset fault.The button is invalid when using the
external terminal to control the drive
ENTER Used to save parameters settings
Reset (back to factory default setting) by pressing ENTER and SHIFT
simultaneously
Self-learning operation steps for permanent magnet motor
1.Set U0-13=0
2.Set motor type U3-32=1 Set the value according to the nameplate of motor: rated
powe U3-33, rated speed U3-34, rated current U3-36, rated frequency U3-37
3.Set U3-60=12
4.Self-learning is activated when “TUNE” appears on the display screen. Press Run
button to start the self-learning which lasts a short period of time ,when it stops
running without any fault,then the self-learning process is finished. Set U0-13=1 to be
PID mode. If run at given frequency, no need to change U0-13.
How to set parameters
The system has two parameter group: 1. U group (function group) ,U group includes U0,U1,U2,U3
subgroups 2. d group (monitoring group)
1) At the original display status, press SHIFT to display sequently running frequency,output current,dc link voltage,temperature and set pressure-current presure. 2) At the orignal displaly status, press MENU and hold for 3 seconds to enter U group ,press MENU
again (do not need to hold for 3secs) to switch to d group
Press MENU for 3 times to return to original display status. 3) After entering U group,press “+” to enter U1.U2.U3 group. Press ENTER to the function code,press
ENTER again to the parameter of the function code, press “+ “and “- “ to modify the parameter and
press ENTER to save the setting.finally press MENU continually for 3 times to return to the original
display status
4) Under stop/running status, press “+” / “-” and hold 3seconds to increase or decrease pressure
The following is the procedure on how to change the sensor range (U0-04)
from 10bar (factory default value) to 15bar. The procedure is the same for
setting other parameters.

3. Quick operation step
1) Target pressure setting
At Stop/running status, directly press Up or Down ( do not need to enter U
parameter group) and hold for 3 seconds,then set the target pressure.. 2) Basic parameters setting
Note: “○” means parameters can be modified at both stop and running status. “●” means parameters can be modified only at stop status. Function

Multi-pump control
1. Terminal wiring diagram
In two master and multi slave pumping system,master and standby master drive are connected to
pressure sensors as below:
When display
smaller than
gauge,increase U0-05. When display
bigger than
gauge,decrease U0-05

1)Multi-Pump Control-Can realize two masters and Max.4 auxiliaries (standby master works as slave) to
combine work. 2）There are two masters (one is master,the other is standby master) and 3 slaves. The standby master
replaces the master to command the whole system only when the master fails to work.The two master
drives are both equipped with pressure transducers,the other auxiliary drives are without transducers. 3).All the drives are connected through a RS485 Communication line. 4) The master detects pipe water pressure through pressure transducer,and sends the pressure signal
to the auxiliaries and automatically controls the auxiliaries to run or stop and PID status according to
the water pressure condition. 5) When master drive failes to work, the standby master will automatically replace the master to controls
the whole system; when any auxiliary drive fails to work, the system will just skip it by and start the next
one, ensuring the automatic shift of pump group. 6) The pumps run alternately (8hours by default) to balance every pump’s running time to prolong
service life of the whole unit machine. 2. Operating steps for multi-pump system
1) Set target pressure on master drive
At Stop status, directly press UP or DOWN ( do not need to enter U parameter group) and hold for 3
seconds,then set the target pressure.. 2)Set sensor type and sensor range on master and standby drive. Function

If any pump’s rotation direction is not correct, refer to one of the following 2 ways to change the the
rotation direction:
a. Modify U0-02 value
b. Exchange any two of U/V/W wiring
4)Adjust display pressure
When display smaller than gauge,increase U0-05.When display bigger than gauge,decrease U0-05
