PID Control (with 4 PIDs)

Allows switching between two types of process commands and feedback values. PID control function that is easy to adjust using an anti-reset windup function to prevent overshoot of PID control and PID output limiter and integral hold/reset signal.
In addition, up to three external actuators can be controlled simultaneously with motor PID control, eliminating the need for a PLC and contributing to system cost reductions.

Linearize

By controlling the pumping pressure at an appropriate value based on the flow rate and target end pressure, it maintains the discharge pressure and reduces wasteful power consumption, contributing to energy-saving effects.

Cascade operation

Function to control multiple pumps with one inverter. Control by combining inverter-driven and commercial power-driven operation. The flow and pressure sensor signals are controlled by the PID controller built-in the inverter, and each pump is driven by commercial power or the inverter using switching signals from the inverter.
As a result, when the discharge flow rate is low, only inverter-driven operation is used, and when the discharge flow rate is high, commercial power-driven operation is used in addition to inverter-driven operation to ensure the necessary total discharge flow rate.

It consists of a combination of a inverter-driven motor (M0), commercial power-driven motors (M1 to M8), and an auxiliary motor (MA). The inverter-driven motor is fixed to motor M0. When the desired discharge flow rate is not achieved with only motor M0, control is performed by sequentially adding commercial power-driven motors.

It consists of a combination of motors(M1 to M4) that can switch betweeninverter-driven and commercialpower-driven operation, and anauxiliary motor (MA) that is driven bycommercial power. Variable speedcontrol using inverter-driven operationat startup. If the desired discharge flowrate is not achieved with only the firstmotor, the operation of FLOATING-1 orFLOATING-2 can be selected.

Each inverter is connected via acommunication link, eliminating theneed for a controller when buildingsystems. In addition, the communicationlink reduces wiring withoutrequiring any additional options.

Constant control of temperature and pressure differences

Reduces wasteful power consumption bylowering fan output when it is difficult to lowerinternal temperatures due to environmentalfactors such as the outdoor air temperaturebeing higher than that of the cooling water.
Temperature can be detected directly with theresistance temperature sensor by using anOPC-PT option card.

Prevention of filter clogging

It detects filter clogging due to dust, etc., based on output current and pressure sensor values, and removes the dust through reverse rotation.
In addition, an alarm is used to indicate that maintenance is required.

Fire Mode

In the event of a fire or other emergency, the inverter's protective function (output shutoff) is partially ignoredand operation is continued. This prevents the buildingfrom being filled with smoke and secures an evacuationpassage.

Supports a variety of networks

Insert the option card into the connector inside the main unit. Up to three cards can be inserted.
Optional communication card types ① DeviceNet　② CC-Link　③ T-Link　 ④ PROFIBUS-DP　⑤ CANopen　⑥ SX bus　 ⑦ Ethernet (EtherNet/IP・PROFINET RT・Modbus TCP)　⑧(BACnet/IP, EtherCAT) Note) There are some limitations to how option cards can be combined. Please contact us for details.
