Enhanced Next Generation Energy Saving Drive

VSD FR-F800

ENERGY SAVING FUNCTIONS SUITABLE FOR VARIOUS SYSTEMS

Standby power reduction:

  • NEW With the 24 VDC external power supply, the input MC signal can be turned OFF after the motor is stopped, and turned ON before activating the motor. The VSD enables self-power management to reduce standby power. The VSD cooling fan can be controlled depending on the temperature of the VSD heatsink. Also, signals can be output in accordance with the VSD cooling fan operation.

Energy saving at a glance – energy saving monitor/pulse train output of output power:

  • Energy saving monitor is available. The energy saving effect can be checked using an operation panel, output terminal, or network. The output power amount measured by the VSD can be output in pulses. The cumulative power amount can be easily checked.

Effective use of the regenerative energy:

  • Multiple VSDs can be connected to the power regeneration common converter or the high power factor converter through a common PN bus. The regenerated energy is used by another VSD, and if there is still an excess it is returned to the power supply, saving on the energy consumption.

COMPATIBILITY WITH THE ENVIRONMENT

Suppression of outgoing harmonic current and EMI: Harmonic current may adversely affect the power supply. To suppress such harmonic current, the power factory improving compact AC reactor (FR-HAL) and the DC reactor (FR-HEL) are available.

Protected in hazardous environments: VSDs with circuit board coating and plated conductors are available for improved environmental resistance.

Global compatibility: The F800 series VSDs are compatible with UL, cUL, EC directives. Being RoHS compliant, the FR-F800 VSDs are friendly to people and the environment.

FUNCTIONS IDEALLY SUITED FOR FANS AND PUMPS

NEW Multiple rating:

The rating can be selected between the two types LD (light duty) or SLD (superlight duty) depending on the load of the fan/pump to be used. The optimum VSD capacity can be selected suitable for the motor to be used.

NEW System cost reduction – PID multiple loops (two loops):

Two PID operation units are available in the VSD. The VSD can perform PID control of the motor operation and control the external equipment at the same time.

Direct setting of the PID set point:

The PID set point can be set directly from the operation panel. The setting can be easily changed at hand.

NEW Water volume control with multiple pumps – multi-pump function:

By controlling the pumps connected in parallel (up to four pumps) by the PID control by one VSD, water volume, etc. can be adjusted.

NEW Visibility improvement:

With the optional LCD operation panel the unit can be changed from “%” to other easy-to-see units. Maintenance and adjustment is facilitated by using a familiar unit of air volume, temperature, etc., for indication.

Energy saving in low speed operation – PID output shutoff (sleep) function:

During PID control, the operation is stopped when the deviation (set point measured value) is small and the output frequency is low, and the operation is restarted when the deviation becomes large. This function restricts energy consumption during low speed operation with low motor efficiency.

NEW Avoidance of rapid acceleration / deceleration using PID action – PID pre-charge function:

Before PID action the water flow to the pipe is controlled by operating the motor at a constant speed until the measured value reaches the set level. This is used to avoid rapid acceleration/deceleration caused by starting the PID action while the pipe is empty, and prevent a water hammer action, etc.

Shorter start-up time under PID control – PID automatic switchover function:
The operation is started without PID control until the output frequency reaches the specified frequency. The system can be started faster at the start of operation.

  • Standby power reduction. Energy saving monitor/pulse train output of output power.
  • Adjusting the air volume by the inverter rotation speed control can lead to energy savings.
  • With the use of high-efficiency motors, further energy saving is achieved.
  • Optimum VSD Capacity Selection. Further Enhanced PID Control – multiple loops.
