Power Options

Circuit Breaker(Leakage Breaker)

Protects Inverter wiring. Install a Leakage Breaker as well if leakage current may cause electrical shock.

Magnetic Contactor

Install to turn the power supply ON/OFF by sequence. Prevents the Braking Resistor from burning out.

AC Reactor

Improves the input power factor of the Inverter and suppresses higher harmonics.

Zero Phase Reactor

To reduce effect of noise interference to radio and control devices.

Input Noise Filter

To reduce effect of noise interference to radio and control devices.

DC Reactor

Improves the input power factor of the Inverter and suppresses higher harmonics.

Backup Capacitor Unit for Momentary Power Loss

For momentary power loss of the control power supply.

Output Noise Filter

To reduce effect of noise interference to radio and control devices.

Drive function enhancement

Option Cards

Option Cards are used to improve the precision of speed control and to extend the external interface.

Variable Resistor Board

The Variable Resistor Board connects to an Inverter terminal. It is used to adjust the frequency reference input and the scales on the Frequency Meter and Ammeter.

Digital Operator

Used to set and read data.

Braking options

Braking Resistor(Use rate 3% ED)

For stopping the machinery within a preset time.(Machinery Mounted)

Braking Unit

Used with the Braking Resistor Unit on an Inverter rated 22 kW or higher.

Braking Resistor Unit(Use rate 10% ED)

For stopping the machinery within a preset time.(Separately Installed)

Accessories
