Yaskawa Drive Decoder

How It Works

1. Type the catalog or model code

   Read the code off the drive nameplate and enter it. GA-series codes are a 7-position catalog code (CIPR-GA50U2030ABAA for a GA500, CIPR-GA80U4302ABAA for a GA800). Legacy A1000/V1000 use the CIMR code (CIMR-AU2A0030FAA); if you only have the model designation, paste it (e.g. 2A0030) to retrieve the ratings. Lowercase, spaces, and unicode dashes are normalized.

2. Read the code breakdown

   The breakdown strip splits a GA-series code into series, region, input voltage, model (output current), EMC filter, enclosure, and environmental specification, each resolved against the selected family. For an A1000/V1000 the strip shows the recognized family and the model/capacity token; the documented CIMR position legend is shown below for reference.

3. Read the HD and ND output current

   The Ratings card shows the Heavy-Duty current and the Normal-Duty current as two distinct numbers, plus the motor HP/kW and voltage class. These are taken verbatim from the Yaskawa technical reference; the app never converts one duty into the other or fabricates a missing figure.

4. Match the motor and check the supply

   The \"What this means for the job\" card translates the rating into motor-sizing guidance (match the motor nameplate FLA to the drive output current, which is the hard limit), the supply it expects, the enclosure, and a duty note. A GA800 T-prefix model flags a 6-phase/12-pulse input that needs a phase-shifting transformer, not an ordinary 3-phase feed.

5. Read the validity verdict

   If the model and voltage combination is not a real cataloged drive, or a required family-specific position letter is out of family, the decoder flags it as invalid and suggests the nearest cataloged neighbour rather than guessing. A trailing suffix that is not the documented standard tail makes the code hard-invalid while still surfacing the matched model's rating for context.

6. Export the decode

   PDF export produces a branded report with the code breakdown, ratings, motor and supply guidance, field notes, cautions, and source pointers. CSV and share carry the same context for documentation and review, not for ordering authorization.

Built For

• A maintenance tech decoding a GA500 CIPR-GA50U2030ABAA nameplate to confirm it is a 7.5 kW / 10 HP, 200 V drive before ordering a spare
• An electrician catching that a 200 V 2030 token is 7.5 kW on a GA500 but only 5.5 kW on a GA800, so the family prefix has to be read before sizing
• A panel builder pulling the Heavy-Duty current of a GA800 CIPR-GA80U4302ABAA (150 kW / 250 HP, 260 A HD) to size feeder conductors and overcurrent protection for review
• A reliability engineer decoding a legacy A1000 CIMR-AU5A0242FAA on an existing 600 V machine and cross-referencing it to a current GA800 before a replacement
• A field tech telling a GA800 6-phase CIPR-GA80UT720ABAA apart from a standard 3-phase feed and confirming the phase-shifting transformer is present
• A buyer decoding a V1000 CIMR-VU2A0010FAA and learning the manual publishes kW only, so the HP has to come off the motor nameplate, not a conversion
• An estimator confirming a fractional GA500 size (CIPR-GA50UB001ABAA is 1/6 HP / 0.2 kW) instead of assuming the smallest drive is 1 HP
• A technician pasting a GA800 hex-frame token (4H12) and confirming it is the 750 kW / 1000 HP big frame before specifying a replacement

Features & Capabilities

Family + Model Lookup, Never Bare Model

Ratings are keyed on the family plus the model token because Yaskawa reuses tokens across families at different kW: a 200 V 2030 is 7.5 kW on a GA500 and 5.5 kW on a GA800, and 2A/4A capacity codes are reused between the A1000 and V1000 at different HD current. The decoder never resolves a bare model.

Heavy-Duty and Normal-Duty, Kept Distinct

Yaskawa publishes two output ratings per drive: Heavy Duty (constant-torque, 150% overload) and Normal Duty (variable-torque, 120% overload). Both are surfaced as separate numbers and neither is ever converted into the other. Where the source publishes only one, the app shows the other as a dash and says so.

Family-Specific Letter Meanings

The region, EMC-filter, enclosure, and environmental letters do not mean the same thing across families. Enclosure A is IP20/Open in GA500 context but IP00/Open on the GA800; the EMC \"filter present\" letter is E on the GA500 and B on the GA800. Every position is resolved against the selected family, never a global table.

HP and kW Taken Verbatim, Fractions Preserved

Motor HP and kW are read straight from the Yaskawa source, including fractional sub-1-HP labels: a GA500 B001 is 1/6 HP and a B004 is 3/4 HP, shown as fractions rather than rounded to 1. The V1000 manual publishes kW only, so HP is shown as a dash and never back-calculated.

Legacy A1000 / V1000 Recognition

The legacy A1000 (CIMR-A) and V1000 (CIMR-V) are recognized from the CIMR prefix and their published ratings returned, with a documented position legend shown for reference. The long CIMR positional string is not position-walked, and the app states that plainly instead of claiming a full decode.

GA800 6-Phase / 12-Pulse Input

A GA800 voltage code of T at position 3 is decoded as a 6-Phase/12-Pulse 400 V input (model tokens T103 through T720), used for harmonic mitigation on large drives. The decoder flags that it needs a phase-shifting transformer supplying two 3-phase sources, not an ordinary 3-phase feed.

Validity Moat, No Fabrication

An uncataloged model, an out-of-family position letter, or a non-standard trailing suffix is flagged as invalid with the nearest real neighbour, rather than interpolating a current or guessing a rating. A real model under an invalid code still has its rating shown for context under a clear \"not a valid code\" headline.

PDF / CSV Export and Light/Dark Theme

PDF export uses the shared ToolGrit generator and includes the code breakdown, ratings, job guidance, field notes, cautions, and source citation. Standard ToolGrit light and dark theme with aria-live result regions so screen readers announce the decode when the code changes.
