How to select YASKAWA GA800 industrial AC frequency converter?

Overview

This document is the GA800 Industrial AC Inverter Selection Guide (document number SL. GA800.01) released by Yaskawa USA in 2021. It introduces the multi voltage levels (240V/480V/600V), dual duty ratings (Normal Duty/Heavy Duty), and corresponding model parameters of GA800 inverters, covering core data for inverter selection (such as output current, power range), supporting components (reactors, filters, braking units, etc.), configuration package solutions (Type 1/12/3R enclosure), technical parameters (overload capacity, protection level, etc.), as well as training services and sales terms, providing comprehensive selection support for Yaskawa salespeople, distributors, and partners.

GA800 inverter core selection parameters

1. Voltage and power range (key numbers)

Voltage level, phase number, power range (HP), core model example, applicable scenarios

240V Class 3-phase 1-150 2004ABM (1HP ND), 2360AWM (150HP ND) low-power motors, such as small pumps/fans

480V Class 3-phase 1-1000 4002ABM (1HP ND), 4H12AAM (1000HP ND) medium and high-power equipment, such as compressors/machine tools

600V Class 3-phase 125-500 5125ABM (125HP ND), 5472AWM (500HP ND) high-voltage industrial scenarios, such as large transmission systems

Scenarios where harmonic reduction is required for 480V 12 Pulse 3-phase 75-1000 T140AAM (100HP ND) and 4H12AAM (1000HP ND), such as medical equipment

2. Performance rating and overload capacity

Normal Duty (ND): Suitable for larger motors, overload capacity of 110% rated current x 60 seconds

Heavy Duty (HD): Stronger torque, overload capacity of 150% rated current x 60 seconds

Example: 240V model 2030ABM, ND 10HP (30A), HD 7.5HP (25A)

3. Model coding rules (taking "GA80U 2 004 ABM" as an example)

Encoding segment meaning optional values/description

GA80U series identification fixed prefix (Americas region)

2 voltage levels 2=240V, 4=480V, 5=600V, T=12 pulse 480V

004 output current corresponds to ND rated current (unit: A, here it is 4A)

A protection level A=IP00, B=IP20, W=Type 12 flange

B environmental specification B=humidity/dust protection (compliant with IEC 60721-3-3 Class 3C2/3S3)

M EMC filter M=Not used (A=Not used, some models in the document default to no filter)

Single/three-phase input adaptation and component selection

1. Single phase input configuration (requires reduced capacity, some require reactors)

Taking 240V single-phase input as an example, the core parameters are as follows (excerpt from Table 5):

Drive model (GA80U) without reactor (ND/HD) with reactor (ND/HD) Input reactor model (Open)

2004... 1/3HP（1.5A）/1/2HP（2.2A） -/- URX000303

2008... 3/4HP（3.2A）/1HP（4.2A） -/- URX000307

2030... 2HP（6.8A）/5HP（15.2A） -/- URX000323

2. Core supporting components

(2) Braking unit

Dynamic braking:
