▶ Standard 1 tow more water supply capacity
There are two relays on the inverter body, which can be equipped with: 1 variable frequency pump + 2 power frequency pumps
Inverter + EM760-IO-A1 expansion card: 1 variable frequency pump + 4 power frequency pumps, using Y1 and Y2 to support up to 7 pumps
▶Fully compatible with ABB-ACS510 inverter water supply solution
You can directly replace the ACS510 without changing the wiring (note that the ABB model is marked according to the light-load rated current)
With sleep/wake function
It has variable frequency pump fixed operation (PFC) mode and cycle soft start (SPFC) working mode
The cycle soft starting mode can also realize the timing rotation function
▶Easy for customers to use
LCD panel display: output frequency, set pressure, feedback pressure
At the same time, the voltage and current feedback channel inputs are configured: AI2 is connected to voltage feedback, AI3 is connected to current feedback
Added software lock pump function, lock faulty pump through function code
▶Protective function
1.Water shortage protection, pipe network overpressure protection, PID feedback disconnection
2.Correspondence between EM760 pump motor and digital output terminals
Sequence Y1, Y2, R1, R2, R3, R4...
If there is a relay expansion board R serial number can continue to increase
If Y1 and Y2 are not set to "74-Water Pump Control (PFC) Output", then the first relay set to "74-Water Pump Control (PFC) Output" is in the front, and the order at this time can be changed to R1, R2, R3 , R4...,
the corresponding wiring of the pump motor
R1: EA/EB/EC
R2: RA/RB/RC
R3, R4 are on the expansion card EM760-IO-A1

Function | EM760 | ACS510 | Remark |
Industry application macro | F16.00 | P9902 | 0:General model 1:Water application |
Pump Control Mode | F51.00 | P8123 | Variable frequency pump fixed mode (PFC) Cyclic soft start mode (SPFC) |
Timed rotation interval | F51.07 | P8118 | Control the timing rotation function, and set the timing rotation time, 0.0h off, >0.0h set the timing rotation interval |
Timing rotation range | N/A | P8119 | Unecessary, when it is close to full load, the timing rotation function is automatically disabled. As long as the pumps are all turned on, the PFC timing rotation will not be performed. |
Electromagnetic switch switching delay time | F51.01 | P8122 | PFC start delay, the delay time to wait for the contactor to be completely closed |
Internal Lock start terminal | F51.09 | P8120 | Set the initial input terminal corresponding to the locked pump, and automatically skip it when encountering a fault |
Motor quantity | F51.02 | P8127 | Set the number of motors, and set the number of relays for PFC output to correspond to this |
Auxiliary machines quantity | NA | P8117 | Unecessary ,Set the number of auxiliary machines, which can be determined automatically according to the PFC, PFC with timing rotation, and SPFC modes |
Auxiliary start frequency | F51.03 | P8109 | Adjust the speed of the main engine to this value, and after maintaining the delay time for starting the auxiliary machine, start one auxiliary machine in sequence |
Auxiliary engine start delay | F51.04 | P8115 | The main machine runs to a specific frequency and keeps the time set by this function code, and the auxiliary machine starts |
Auxiliary Shutdown frequency | F51.05 | P8112 | The master adjusts the speed to this frequency, and keeps it until the auxiliary machine stops and delays, then listens to one auxiliary machine in sequence |
Auxiliary shutdown delay | F51.06 | P8116 | The main machine runs to a specific frequency and keeps the time set by this function code, and the auxiliary machine stops |

5.Water supply function table—the unique function of EM760
Function | EM760 | Remark |
lock water pump 1 | F51.10 | Through the function code setting, lock the corresponding pump 0: Not locked 1: Locked water pump, factory default 0 |

Water shortage protection function | F51.18 | 0: off (factory default) 1: open, judged by outlet pressure 2: Open, judged by frequency and current |
Water shortage protection threshold value | F51.19 | When the feedback water outlet pressure is less than the water shortage protection detection threshold and remains beyond the water shortage protection detection time, it will report water shortage protection, E59 water shortage protection |
Water shortage protection detection time | F51.20 | |
Water shortage protection detection frequency | F51.21 | When the output frequency > water shortage protection detection frequency, start to judge whether there is water shortage, and the output current < the set water shortage protection detection current (percentage relative to the rated current of the motor), and keep exceeding the water shortage protection detection time, then report water shortage Protect |
