| Starting torque： | 0.5Hz 100% |
| Speed adjustable range： | 1:100 |
| speed-holding precision： | ±1.0% |
| Overload capability： | 150% rated current for 60s; 180% rated current for 1s |
| Acceleration/deceleration time： | Range: 0.01 ~ 360s |
| Start frequency： | 0.01~10.00Hz |
| Input voltage： | 220V/380V±15% |
| Input frequency range： | 50/60Hz, fluctuation range: ±5% |
| Output voltage： | 0 ~ rated input voltage |
| Output frequency： | 0~50/60Hz |
| Programmable digital input： | 6 ways of digital terminal input |
| Programmable analog input： | AI1: 0/4 ~ 20mA; To switching 0~10V by setting parameters AI2: 0/4 ~ 20mA; To switching 0~10V by setting parameters |
| Relay output： | 2 way of output, programmable |
| Open-collector output： | 1 way of output, programmable |
| Analog output： | Reserved |
| Command running channel： | Three kinds of channels: 1. operation panel 2. control terminal 3.serial communication port, choose 1 and 2 for host drive and 3 for auxiliaries |
| Multi-Pump Smart Link： | One drive in the system can be host and controls auxiliaries(4 at most) to work by communication mode. Host sends PID feedback to auxiliaries and monitors status of auxiliaries in real time. If failure occurs, the auxiliary will be skipped. |
| Integrated PID： | Advanced PID arithmetic to realize closed loop control system |
| AVR： | When grid voltage changes, it keeps output voltage constant automatically. By default, it doesn’t work at deceleration. |
| Stall control： | Automatically limit current and voltage at running period to prevent tripping caused by frequent overcurrent/overvoltage. |
| Water shortage protection： | Controller detects that pipe network pressure is lower than water shortage pressure, system stops working automatically. After set period, it restarts automatically for specified times. If pressure restores to normal, system works normally. Otherwise, system stops automatically in case of idle running of pump and prolongs pump lifetime in maximum. |
| High pressure alarm： | When pressure exceeds set pressure, it stops automatically to prevent pipe network from high pressure. |
| Automatic energysaving running： | Decrease output voltage automatically at light load to save energy. |
| Password setting： | 4-bit password can be set with non-zero numbers. Exit password setting interface and the password will be valid after 1 minute. |
| Parameter lock： | Define whether the parameter is locked in running or stopped state in case of misoperation. |
