Stable System Control

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

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.

Energy-saving Display (Payback Counter)
Commercial energy consumption is compared to the amount of energy used by the drive to calculate the amount of energy saved.

Scheduling (Time Event: Real Time Clock)
Operation schedule can be set to meet the user or system demand in certain times. RTC (Real Time Clock) is used so that selected functions are operable during the set time.

Soft Fill Operation
Prevents pump damages caused by dramatic pressure changes during initial 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.

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.

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.

Detection of Pipe Broken
Upon PID operation, pipe damages or leakage is detected to display a warning or a trip.

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.

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.

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

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.

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.

Maximized User Convenience

Communication Module

  • RS-485 Capability is built-in
  • Modbus-RTU, Metasys N2
  • BACnet MS/TP is embedded as standard
  • LonWorks option can be added

Keypad Exclusive for HVAC
Used to issue commands, configure drive parameters, and for monitoring drive status

  • HAND mode (Local, Control, Mode) or AUTO Mode (Remote Control Mode) can be selected.
  • HAND Mode : Used when selecting frequency or run/stop commands.
  • AUTO Mode : Drive operated using the keypad. multifunctional terminal block and communication.
  • Fault Status Monitoring.

DC Reactor
A built-in DC Reactor effective to improve power factor and reduce THD is installed. DC Reactor built-in as standard for 400V 37-90kW

Builit-in EMC Filter
A built-in EMC fiter to respond to the specifications for noise reduction

  • 400V 0.75~30kW Built-in as default (C3)
  • 400V 37~55kW Built-in option can be selected (C3)

※ 75~90kW satisfies EMC specifications even without a filter.
