Scheduling (Time Event: Real Time Clock (RTC))

Using RTC, user can program following operating schedules for general or exceptional dates

RTC is used so that selected functions can be operated during set time (Possible to set different functions including Fx, Rx, Multiple Acceleration /Deceleration time, multiple frequency & PID, Pre-heat etc.)

Using RTC, user can program following operating schedules for general or exceptional dates

• 4 Time Period module (Weekly)
• 8 Exception Date module (Day)
• 8 Time Event module
• 29 Functions available (Fx, Rx, Step Freq., PID, etc.)
• Summer Time available (Start/End date setting)
• 3 Type of Date displaying available (EU / USA / ASIA)

Multi-Motor Control (MMC): Booster Pump

MMC is used when a single drive is required to control multiple motors in pump systems.

It can control 1 main motor through PID and 5 auxiliary motors through Drive & Relays, an Ideal cost-effective solution for constant pressure / constant flow pumping application.

Dry Pump (Under Load Protection)

Prevents pump damage when there is insufficient water in the tank. If Actual load is under the Under Load (UL) Detect curve, Inverter will trigger warning or trip signal to protect the pump.

Payback Counter

It displays energy saving information by comparing the average energy efficiency for operation with and without the inverter. The energy saving information is displayed as kWh, saved energy cost and CO2 emission level.

Fire Mode

When an emergency such as fire occurs at suction/exhaust fans, without any hardware failure or a critical defect, the drive continuously operates to protect other systems under the set frequency and direction.

Flow Compensation

In a system for longer pipes & higher flow rate, causing great pressure drop, this feature helps to compensate for pressure drop by increasing the PID reference.

Pump Clean Operation

Scraps, which get built up in impellers of pumps, decrease the efficiency of motor performance. Through consecutive FWD/REV or ACC/DEC operation, the scraps get eliminated.

This results in extension of pump lifespan and energy saving. The pump clean mode is initiated by- remote signal, current profile or power profile.
