Overview Manuals Gate Drive Links Fiber Test Fault Isolation Cell Checks

Features:

  • IS200IGDMH1B provides the gate-driver endpoint for an IGBT bridge cell.
  • A fiber-optic link connects the IGDM board to the IS200FOSA interface.
  • Continuous optical return lets bridge control monitor communication with the cell.
IS200IGDMH1B participates in a drive bridge where each indicated cell has a defined optical communication position.

Link verification for IS200IGDMH1B depends on the observed order of the gate-driver LEDs rather than a software-generated pass/fail explanation.

Because several hardware and wiring conditions can interrupt return light, IS200IGDMH1B troubleshooting must keep the optical path, board power, and associated IGBT state separate.

The General Electric IS200IGDMH1B IGBT Gate Driver Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Optical Cell Path

  • Cell endpoint: IGDM provides the gate-driver board at the IGBT bridge cell.
  • Interface board: IS200FOSA is the fiber-optic hub for the gate-drive links.
  • Return signal: Normal operation includes continuous light from IGDM to FOSA.
  • Trip basis: Loss of the return signal creates the IGDM communication fault.

Link Verification Method

  • Wizard: The Fiber-Optic Test checks FOSA-to-IGDM connections.
  • Observation: Each gate-driver LED must appear in the defined cell sequence.
  • Repetition: The sequence is repeated three times unless aborted by a user or fault.
  • Result limit: The test supplies no automated diagnostic conclusion.

Lost-Link Investigation

  • Board candidates: IGDM, FOSA, CPFP, and BICM remain within the fault boundary.
  • Fiber path: A damaged or misplaced optical connection can remove return light.
  • Power path: CPFP distribution wiring and supply condition must also be checked.
  • IGBT condition: A desaturation event can produce the same communication symptom.

Bridge Test Coverage

  • Short paths: The cell test detects unintended conduction in the inverter bridge and load.
  • Open paths: Expected bridge conduction paths and shunt feedbacks are evaluated.
  • Voltage feedback: The wizard checks whether bridge voltages are measured correctly.
  • Dynamic brake: Additional cell checks run only when that option is installed.
Description
General Electric IS200IGDMH1B is an IGBT Gate Driver Board associated with the bridge cells of an Innovation Series medium-voltage drive. Its gate-drive communication path is paired with an IS200FOSA fiber-optic interface board.

During normal operation, IS200IGDMH1B returns continuous light to the FOSA interface. Loss of that optical return causes the bridge control to report loss of communication with the indicated IGDM module rather than identifying a single cause by itself.

The fiber-optic test for IS200IGDMH1B verifies the connection between FOSA and the IGDM boards by a defined LED lighting sequence. The test does not generate an automatic diagnosis, so the observed sequence must be compared with the expected cell order.

When an IGDM communication fault involves IS200IGDMH1B, the investigation boundary includes the IGDM, FOSA, CPFP power supply, BICM, the fiber connection, and the CPFP power-distribution wiring. A desaturation fault on the associated IGBT can also remove the return-light condition.

Technical notes
IS200IGDMH1B forms the optical gate-drive endpoint for an IGBT cell and reports link integrity to the IS200FOSA interface through return light.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
The drive reports loss of communication with IS200IGDMH1B. Does that message prove the gate-driver board alone has failed?
No. Loss of return light from IS200IGDMH1B can also involve the FOSA interface, CPFP supply, BICM, fiber connection, power-distribution wiring, or a desaturation event on the associated IGBT.
Why can the Fiber-Optic Test finish without naming the fault on IS200IGDMH1B?
The test checks the link to IS200IGDMH1B through an LED lighting sequence; it does not perform automated diagnosis, so the sequence must be inspected visually.
An LED in the IS200IGDMH1B cell order never illuminates during the test. Which physical path should be verified first?
Check the fiber-optic connection between FOSA and IS200IGDMH1B together with the CPFP power-distribution wiring before separating board and IGBT causes.
A desaturation event and an IGDM communication fault appeared together. How are they related to IS200IGDMH1B?
A detected desaturation fault on the indicated IGBT can stop the continuous optical return from IS200IGDMH1B and trigger the same lost-communication trip path.
Which wizard covers bridge conduction problems after the optical path to IS200IGDMH1B has been checked?
Use the Bridge Cell Test path for short-circuit detection, open-circuit detection, and voltage-feedback evaluation; the separate fiber test focuses on the FOSA-to-IS200IGDMH1B connection.
After an IGBT failure in one phase, should IS200IGDMH1B be excluded from the damage review?
No. The drive instructions include the IGDM board in the affected-phase review because an IGBT failure can also damage the associated IS200IGDMH1B gate-driver path.
