Hyundai INV FS GATE / INV FM GATE Inverter Gate Board

The Hyundai INV FS GATE and INV FM GATE Boards are inverter gate drive PCBs used in Hyundai elevator drive systems. They form part of the inverter power control section and are used to control the power module according to the drive configuration.

FS and FM Are Selected by Inverter Capacity

Although INV FS GATE and INV FM GATE belong to the same gate board family, they are intended for different inverter capacity ranges.

In Hyundai HIVD900 applications, the typical configuration is:

• INV FS GATE / H9G FS GATE Bd: 5.5 kW and 7.5 kW

• INV FM GATE / H9G FM GATE Bd: 11 kW and 15 kW

This distinction is important when sourcing a replacement. The two boards should not be selected only by appearance.

Motor System Also Needs Attention

Hyundai documentation shows FS and FM Gate Boards in both 900G asynchronous motor and 900SS/GT synchronous motor drive systems.

However, the connector configuration can differ according to the inverter system. The original gate board and complete inverter nameplate should therefore be checked together.

For replacement confirmation, please provide:

• Board marking: INV FS GATE or INV FM GATE

• PCB revision

• Inverter model

• Rated inverter power

• Front and rear PCB photos

• Connector arrangement

• Motor type

• Inverter nameplate

• Required quantity

FAQ

What is the difference between INV FS GATE and INV FM GATE?

The main difference is the inverter capacity range. FS is commonly used for 5.5/7.5 kW drives, while FM is used for 11/15 kW configurations.

Are INV FS GATE and INV FM GATE interchangeable?

No. They correspond to different inverter power ranges and should be matched according to the original drive configuration.

Is Rev5.0 the only available version?

Rev5.0 is commonly found in the spare-parts market, but other versions may exist. Always confirm the revision printed on the original PCB.
