Nabtesco ARN30 VIGO SERVO Drive

Description

Key Technical Specifications

The published AR-series documentation identifies ARN30 as the compatible servo amplifier for the AR30 actuator. The AR30 actuator uses an RV-40E reduction gear, with motor output listed at 0.8 kW.

The manual also specifies 4.5 Arms continuous output and 16 Arms maximum output for ARN30, together with the 3-phase 200–230 V supply range.

Product Introduction

Nabtesco ARN30 is an AC servo amplifier/controller in the VIGO SERVO AR Series, designed to operate compatible AR-series servo actuators such as AR30. It uses transistor PWM control and provides positioning, pulse-train, speed-command, JOG, and related control functions.

The ARN30 is particularly relevant when maintaining legacy Nabtesco AR-series motion equipment. Its documented electrical rating is 1.5 kVA with 4.5 Arms continuous and 16 Arms maximum output. Confirm the exact ARN30 revision, actuator model, and wiring configuration before replacement.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation — About 5–10 Minutes

⚠️ Safety First: Treat the as a mains-powered servo amplifier. Stop the machine, place the equipment in a safe state, isolate the incoming power, and apply your site’s lockout/tagout procedure. Do not begin wiring work until the DC bus has discharged and the absence of hazardous voltage has been verified.

Tools Required:

• ESD wrist strap
• Insulated screwdriver set
• Multimeter
• Wire labels
• Smartphone or camera
• Original Nabtesco documentation

Before removing the existing amplifier:

1. Record the complete model and suffix from the nameplate.
2. Photograph all terminals and connectors.
3. Record the existing parameter settings.
4. Photograph any selector switches or configuration settings.
5. Record the connected AR actuator model and reduction ratio.
6. Back up machine-side positioning parameters where applicable.
7. Keep the existing available until commissioning is complete.

⚠️ Do not assume that an with a similar-looking housing has an identical configuration. Legacy servo systems can contain revision-specific wiring and parameter requirements.

Stage 2: Removing the Old Module — About 5 Minutes

1. Confirm power isolation with a multimeter.
2. Remove the required front cover or protective panel.
3. Label each motor, encoder, brake, control, and power connection.
4. Disconnect wiring without pulling directly on cable conductors.
5. Release the mounting hardware.
6. Remove the amplifier carefully and protect exposed connectors.
7. Inspect the mounting area for contamination, loose terminals, or damaged wiring.

⚠️ Keep the old amplifier for reference. Do not dispose of it until the replacement has completed functional testing.

Stage 3: Installing the — About 5–10 Minutes

1. Verify the replacement nameplate against the removed unit.
2. Check that the model is and confirm the applicable revision/suffix.
3. Inspect connectors for bent pins, contamination, or mechanical damage.
4. Mount the amplifier in the original position.
5. Reconnect the power wiring according to the applicable Nabtesco wiring diagram.
6. Reconnect motor and encoder wiring.
7. Reconnect brake and control I/O connections.
8. Confirm protective grounding.
9. Tighten terminals using the applicable manufacturer’s torque specification.

Configuration Clone — Critical:

Do not simply power up the replacement and assume the previous settings are retained. Restore the documented machine parameters and positioning configuration according to the applicable ARN-series manual.

Self-Checklist:

• Correct model confirmed
• Power wiring verified
• Motor wiring verified
• Encoder connection verified
• Brake wiring verified
• Grounding verified
• Parameters backed up/restored
• Mounting hardware secured

Stage 4: Power-On & Testing — About 10 Minutes

1. Perform a final wiring and short-circuit check before energizing.
2. Energize the servo system while keeping the machine in a safe state.
3. Observe amplifier status indicators.
4. Check for immediate alarms.
5. Confirm encoder feedback.
6. Verify servo ON/interlock operation.
7. Test the positioning command at low risk.
8. Check direction of rotation.
9. Perform a controlled JOG or positioning test.
10. Run the axis through its required operating range before returning it to production.

⚠️ Do not immediately run the axis at full speed. An incorrect encoder connection, motor phase connection, positioning parameter, or direction setting can produce unexpected motion.

Nabtesco documentation lists overload, overspeed, overvoltage, motor-overheat, battery, and signal-line-disconnection protection functions for the ARN-series system.

Frequently Asked Questions (FAQ)

Can the Nabtesco be hot-swapped?

Do not assume that it can. The is a mains-powered servo amplifier, so replacement should be performed with the system safely isolated and the absence of hazardous voltage verified. Follow the applicable Nabtesco manual and your site’s LOTO procedure.

What servo actuator is compatible with ?

The AR-series catalog identifies as the compatible servo amplifier for AR30. The AR30 high-torque actuator uses an RV-40E reduction gear and a 0.8 kW motor.

What is the ‘s output rating?

The documented rating is 1.5 kVA, with 4.5 Arms continuous output current and 16 Arms maximum output current.

What input power does require?

The documented supply is 3-phase AC 200–230 V, +10% / −15%, 50/60 Hz. The control supply is listed as DC 24 V ±10%.

Is an obsolete model?

The available Nabtesco AR documentation is published as discontinued-series documentation, so should be treated as a legacy model for procurement and replacement planning. That does not by itself establish that every installed unit is unavailable. Check current Nabtesco support and your exact nameplate revision before specifying a substitute.

Will replacing erase my machine parameters?

Do not count on the replacement containing the original machine configuration. Back up the existing parameters before removal and document the positioning settings. The replacement should be configured against the actual machine and applicable Nabtesco manual rather than copying assumptions from another installation.

Is the same as -A?

Do not treat the two designations as automatically interchangeable. -A appears in secondary inventory listings, while Nabtesco’s published AR documentation identifies /-F variants in its documentation. Verify the complete nameplate, revision, connectors, and machine configuration before ordering a replacement.
