5. Electrical Rating

The primary electrical rating of the 20G1ANF142JA0NNNNN is 142 A.

At normal duty, the drive provides approximately 132 kW of motor-power capacity.

At heavy duty, the rating is approximately 110 kW.

This makes the model suitable for large industrial motors where a substantial amount of continuous power is required.

The 690 V operating class is particularly useful for large motor systems because high motor power can be delivered at a lower current than would be required at lower voltage levels.

When selecting the drive, the motor’s actual nameplate current should be compared against the drive rating.

Motor horsepower or kW alone should not be used as the only selection criterion.

6. Normal-Duty and Heavy-Duty Ratings

The difference between normal-duty and heavy-duty ratings is important when selecting this drive for a specific machine.

Duty Classification	Power Rating	Output Current Class	Typical Application
Normal Duty	132 kW	142 A	Pumps, fans, blowers and variable-torque equipment
Heavy Duty	110 kW	142 A class	Conveyors, mixers, compressors and higher-torque equipment

The 132 kW normal-duty rating is suitable for large continuous-duty equipment.

The 110 kW heavy-duty rating provides a more conservative motor-power rating for applications with greater torque demand or more demanding acceleration conditions.

For the final selection, the motor nameplate current, load profile, acceleration time and overload requirements should all be considered.

7. Product Introduction

The 20G1ANF142JA0NNNNN is a high-power industrial variable frequency drive designed for controlling three-phase AC motors in 690 V electrical systems.

The drive is designed for applications where the motor needs to operate at variable speed rather than simply running continuously at a fixed frequency.

It can provide controlled motor acceleration, adjustable operating speed and controlled deceleration.

The 142 A output rating places this model at the upper end of the Frame 6 690 V range.

With a normal-duty capacity of 132 kW, it is suitable for substantial industrial machinery.

The model also incorporates an internal dynamic braking transistor, making it more suitable than a configuration without the transistor for applications where braking-energy management is required.

Embedded EtherNet/IP communication allows the drive to be incorporated into a larger automation system.

8. 690 V High-Power Architecture

The 690 V rating is a major characteristic of the drive.

Large industrial motors commonly use higher-voltage electrical systems to reduce current for a given power level.

This is useful in large plants where motors may operate at tens or hundreds of kilowatts.

Typical 690 V applications include:

• Mining equipment
• Water-treatment equipment
• Chemical processing
• Cement production
• Steel processing
• Large ventilation systems
• Industrial pumping
• Material handling
• Process machinery
• Large production equipment

The 20G1ANF142JA0NNNNN is therefore designed for industrial electrical systems rather than small commercial motor applications.

9. Frame 6 Construction

The model uses a Frame 6 mechanical configuration.

Frame size affects the installation footprint, cabinet design, cooling arrangement and maintenance access.

The approximate drive dimensions are:

665.5 × 308 × 346.4 mm

Approximate weight:

48–50 kg

The drive should be installed with sufficient space for:

• Input power cables
• Motor cables
• Grounding conductors
• Communication wiring
• Cooling airflow
• Service access
• Terminal access
• Cable bending radius

The complete cabinet should therefore be larger than the drive itself.

10. Dimensions and Weight

Physical Parameter	Approximate Value
Model	20G1ANF142JA0NNNNN
Width	Approx. 308 mm
Height	Approx. 665.5 mm
Depth	Approx. 346.4 mm
Approx. Weight	48–50 kg
Frame	Frame 6
Cooling	Forced Air
Installation	Cabinet / Panel

The dimensions and weight should be regarded as engineering reference values.

Actual shipping weight and installation dimensions can vary depending on packaging, accessories, mounting hardware and the final system configuration.

For cabinet fabrication, the relevant mechanical drawing for the exact configuration should be used.

11. Cooling System

The 20G1ANF142JA0NNNNN uses forced-air cooling.

At this power level, effective heat removal is essential.

The drive’s power section generates heat during operation, and the cooling system moves air through the heat-producing components.

The cabinet should provide an appropriate airflow path.

Important considerations include:

• Ambient temperature
• Cabinet temperature
• Air inlet clearance
• Air outlet clearance
• Fan condition
• Dust accumulation
• Ventilation filters
• Cabinet heat dissipation
• Distance from other heat-producing equipment

A dirty or obstructed ventilation system can increase operating temperature and reduce equipment reliability.

12. Dynamic Braking

One of the important characteristics of the JA configuration is the inclusion of an internal dynamic braking transistor.

The transistor provides a means of controlling braking energy when the motor is decelerating and energy is returned to the drive’s DC bus.

The drive does not include an internal braking resistor.

If dynamic braking is required, an appropriate external braking resistor and braking arrangement must be selected according to the application.

Dynamic braking can be useful in equipment with:

• High rotational inertia
• Rapid stopping requirements
• Frequent acceleration and deceleration
• Conveyor systems
• Centrifugal equipment
• Material-handling machinery
• Large rotating loads

The required braking resistor capacity depends on the motor, load inertia, stopping time, duty cycle and required braking torque.

13. JA and JN Configuration Comparison

The 142 A model is available in configurations with different braking arrangements.

Model	Current	Normal Duty	Heavy Duty	Dynamic Braking
20G1ANF142JA0NNNNN	142 A	132 kW	110 kW	Internal DB Transistor
20G1ANF142JN0NNNNN	142 A	132 kW	110 kW	No Internal DB Transistor

The two models share the same basic voltage, current and power class, but the configuration is different.

This distinction is important when replacing an existing drive.

A replacement should be matched according to the complete catalog number and the actual braking requirements of the machine.
