Toshiba VFAS3-2185P Control Terminal Board – VF-AS3 Tested

What Is the VFAS3-2185P Control Terminal Board?

The VFAS3-2185P control terminal board is the signal interface and control wiring board for the Toshiba TOSVERT VF-AS3 series. The base model VFAS3-2185P is a three-phase 200/240 V, 18.5 kW, 78.4 A drive in the Frame 6E size. The control terminal board routes external start/stop commands, analog references, digital inputs, and relay outputs between field wiring and the drive’s main control circuit.

It is a passive terminal interface board, not the main CPU board or the power stage. Supplied as Tested replacement stock.

Key Specifications

When This Board Is the Suspect

The control terminal board becomes the replacement target when signal-level symptoms persist after external wiring and parameter checks:

• Analog input disconnection alarm (E-18) — the drive reports an analog input disconnection. If the external signal source and wiring are confirmed normal, the terminal board’s analog input path should be inspected.
• Option fault in a slot (E-23 / E-24 / E-25) — an option card in slot A/B/C reports a fault. The control terminal board hosts these option slots; a poor connection between the option card and the terminal board can trigger these alarms.
• Control power option failure (E-29) — the control power supply option has failed. The terminal board carries the interface for this option; reseat and inspect the board before replacing it.
• Control inputs not responding — start/stop or digital inputs are correctly wired and configured, but the drive does not respond. Damaged terminals or poor contact on the control terminal board can interrupt the signal path.

Compatibility Check

Before ordering, confirm:

• Original board marking — confirm the existing terminal board carries the part number VFAS3-2185P (or the board-level identifier printed on the label).
• Drive frame size — VFAS3-2185P belongs to Frame 6E. The same terminal board may be shared across a limited frame range, but fitment is frame-dependent.
• Option slot configuration — if the drive uses option cards (E-23/24/25 alarms), confirm the slot arrangement matches the replacement board.
• If unsure, send a photo of the original terminal board and the drive nameplate before purchase.

FAQ

Is VFAS3-2185P a Schneider product?

No. VFAS3-2185P is a Toshiba TOSVERT VF-AS3 drive model. The control terminal board carries the same model identifier for the 18.5 kW / Frame 6E unit. Confirm the drive nameplate reads Toshiba VF-AS3 before ordering.

Does E-23 always mean the terminal board is faulty?

No. E-23 is an option fault in slot A. The option card may be loose, damaged, or incorrectly inserted. Reseat the option card and verify the connection at the terminal board before replacing the board itself.

Does this board cover the entire VF-AS3 series (0.75–160 kW)?

No. VFAS3-2185P is specific to the 18.5 kW / Frame 6E configuration. Other power ratings use different terminal board variants. Confirm your exact drive MLFB and frame size before ordering
