Side-by-Side Installation

  • The size of control board is significantly reduced when multiple drives are installed by minimizing distance between products installed.
  • Sibe-by-side installation is unavailable for 37~90kW.

LSLV-H100 drives are intelligent drives equipped with various protective and operation functions for continuously stable operation in response to external environmental changes.

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

Dec Valve Ramp

  • Prevents pump and pipe damages caused by sudden pressure changes when pumps are stopped or a pump valve is closed, deceleration time can be set.

Multi Motor Control

  • MMC is used when a single drive is used to control multiple motors in pump systems. It can control 1 main motor and 5 auxiliary motors.

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.

Energy-saving Display (Payback Counter)

  • Commercial energy consumption is compared to the amount of enery used by the drive to calculate the amount of energy saved.

Power-on Resume

  • When the drive restarts after it was stopped due to power interruption upon communication control, ‘Power-on Resume’ is used to follow the previous control command.

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.

Auto Torque Boost

  • The drive outputs voltage for the drive by controlling the level of boost to fit the load by itself.

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.

Detection of Pipe Broken

  • Upon PID operation, pipe damages or leakage is detected to display a warning or a trip.

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


  • Pre-heats motors by outputting direct current when the motors are at fixed time state in order to prevent condensation of the motors

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.

Macro Setting

  • If a particular application is selected, frequently used parameters and set values are changed and registered in a macro group

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
