Soft Fill Operation
Prevents pump damages caused by dramatic pressure
changes during intial operation or pumps or inside
pumps.

 Start Ramp & End Ramp
 Prevents pump damage by changing ramp using
 acceleration / deceleration time setting upon initial
 pump operation and stop

Scheduling (Time Event: Real Time Clock)
Prevents pump damages caused by dramatic pressure
changes during intial operation or pumps or inside
pumps.

 Flow Compensation
 Compensates for hydraulic loss that occurs when the
 length of pipes is long, adding compensation rate
 depending on the inverter output frequency.

Sleep, Sleep Boost, Wake-up
It is used to put the drive on standby and restarts it
using amount of enery used by the drive to calculate
the amount of energy saved.

Lubrication Control
When a control command is made in the Flow/Oiling
Systems, lubrication signals are output for a certain
period before the motors are started. Drive control is
immediately started form the signal output point until
the signals are turned off after the set time

 Damper Control 
 When a Damper exists in the system configuration,
 the drive will command the Damper to open/close or
 receive feedback signals for protection. 
 

Level Detection
 When the drive is operated under frequency that is
 beyond the set frequency and source (voltage, current,
 and etc.) values to be detected are above or below the
 user set values, it generates a trip or activates a
 relay for protective operation

 Under Load Protection
 When running pumps including No Flow and Dry Pumps
 under the set frequency. the drive issues warning
 function and when trip is generates, Free-Run,
 deceleration, or stop can be selected via parameters.

 KEB, Kinetic Energy Buffering
 Upon loss or momentary interruption of input power,
 if KEB is set, the drive maintains DC Link Voltage using
 regeneration energy of the motor is used during the
 interruption period.

Pump Clean
Upon pump operation, the efficiency of pumps may
decline when foreign substances are stuck in an
impeller. Pump Clean removes the foreign substances
to extend the pump life and reduce any loss

 Aux Motor PID Compensation
 Pipe flow increases and conduit pressure decreases
 as the number of auxiliary motors increases. To
 compensate this, 'Aux Motor PID Compensation' is
 used to compensate pressure loss suitable for the
 given motor when operating auxliary motors.

Load Tuning
Establishes load (current & power) curves based on
drive frequency so as to make load characteristics
curve required for 'Under Load' and 'Pump Clean.'
 

 Fire Mode
 When an emergency such as fire occurs at suction/
 exhaust fans, but hardware did not fail nor had a
 critical defect, the drive is continuously operated to
 protect other systems under the set frequency and
 direction.
