CHUCK CONTROLLERS

Product catalog summary

Overview

This document provides detailed technical information on various models of electromagnetic chuck rectifiers, demagnetizers, selector switches, and chuck masters used for controlling electromagnetic chucks. It covers specifications, applications, features, selection guides, connection diagrams, troubleshooting, and wiring accessories.

1. Rectifiers for Electromagnetic Chucks

Models KR-N and KR-T

Application: Convert AC power to DC to supply electromagnetic chucks, with KR-T allowing variable output voltage to control holding power.
Features: Compact size (50% volume reduction), external control terminals for automation, included power cables and plugs, stable output voltage above 30 V (KR-T), and compatibility with 100 VAC and 200 VAC power sources.
Specifications: Output voltages typically 90 VDC or up to 120 VDC, currents from 1A to 5A depending on model, dimensions and weights vary by model.

Model ESR Series (ESR-N102 and ESR-5A)

Application: Rectify AC to DC and provide manual demagnetization via attenuating alternating output.
Features: Manual dial for reversing circuit and resistance adjustment to facilitate demagnetization for diverse workpieces.
Note: ESR-5A requires a separate rectifier upstream.

2. Selector Switch Model S-2A

Application: Manually relays DC output from rectifier to electromagnetic chucks and selects output for demagnetization.
Features: Simple, lightweight, easy installation, robust construction.
Electrical Rating: Max 120 VDC, 2A.

3. Electro Chuck Masters (Models ES-V, ES-M, EH-V, VE)

Application: Integrated rectifier and electronically controlled demagnetization circuits for automatic demagnetization and variable or constant DC output to electromagnetic chucks.
Features: Suitable for large or high-capacity chucks, stable low voltage range, automatic demagnetization with programmable timing, remote operation box available.
Specifications: Output currents range from 3A to 30A, output voltages up to 90 VDC, dimensions and weights vary significantly with model.

4. Selection Guide

Rectifier Selection

Ensure rectifier output voltage ≥ electromagnetic chuck voltage.
Rectifier output current must exceed chuck current.
Allow margin for voltage fluctuations and current capacity (e.g., for a 4.5A chuck, select rectifier with ≥6A output).

Demagnetizer Selection

Requires a compatible rectifier.
Cannot be used with Electro Chuck Masters.
Manual demagnetizers (S-2A, ESR-5A) only connect to rectifiers.

Function-Based Model Selection

Models vary by presence of variable output, automatic/manual demagnetization, and rated current capacity.
Examples: ES-V supports variable output and auto demagnetization up to 27A; ESR-N102 supports manual demagnetization with 1.8A output.

5. Connection Diagrams and Wiring

Multiple electromagnetic chucks can be connected and controlled by one Chuck Master using terminal boxes (TB series) that integrate wiring.
Terminal boxes available for 2 to 10 circuits, with detailed dimensions and mounting hole specifications provided.
Wiring examples and mounting hole pitches are specified for proper installation.

6. Troubleshooting Guide

Common Issues: Residual holding power too large, weak holding power, no holding, fuse blowing, demagnetization failure, alarm indicators.
Checks and Actions: Verify power supply and voltage, replace blown fuses, adjust output voltage or demagnetization variable resistors, inspect wiring for breaks or shorts, measure insulation resistance (should be above 5 MΩ), and ensure proper magnet suitability for workpieces.
Safety Note: Power must be turned off before inspection; use warning tags if equipment is out of order.

7. Technical Data Summary

Dimensions, weights, electrical ratings, and mounting hole details are provided for all models.
Output voltages range typically from 0 to 120 VDC, currents from 1A to 30A depending on model.
Power sources are mainly single-phase 100 VAC or 200 VAC at 50/60 Hz.

Critical Information and Best Practices

Always select rectifiers and chuck masters with output ratings exceeding chuck requirements with safety margins.
Use automatic demagnetization where possible for consistent residual magnetism reduction.
Manual demagnetizers require careful adjustment and are suitable for diverse workpieces.
Ensure proper wiring and insulation to prevent faults and maintain safety.
Refer to troubleshooting guide before requesting repairs or parts replacement.

Also when demounting a workpiece after machining, electrical demagnetization is required to reduce tlie residual lidding power. For this purpose, an Electro Chuck Master or a chuck controller consisting of a rectifier and demagnetizer (Chuck Master dedicated to demagnetization and selector switch) is required. •Rectifier: Rectifies an input from an alternating current (AC) power source to direct current (DC) and supplies it to the electromagnetic chuck. •Demagnetizer. Once a workpiece has been attracted to the electromagnetic chuck, it cannot be demounted easily due to its residual holding power even when the power is turned off. The demagnetizer is used to attenuate the DC power from the rectifier and eliminate the residual magnetism. Model EH-V NON-CONTACT TYPE CHUCK MASTER* <EH-V305A> W & ViewE Remote operation type [Application] Rectifies an input from an AC power source to DC and outputs it to the electromagnetic chuck. [Features] •Developed as a non-contact type Chuck Master capable of outputting a constant voltage in a wide range of 100 VAC to 220 VAC and providing high speed consistent demagnetizing effect. Also various protective functions have been incorporated and indicator lamps for individual alarms are provided to identify alarms easily. •Because a relay (consumable part) is not used, this model can he used continuously and withstand frequent ON/OFF operations. •The holding power of the electromagnetic chuck can be controlled by adjusting the voltage. •The rapid automatic demagnetization function is activated to reduce the residual holding power of the electromagnetic chuck. •Many input/output signals are employed that can be utilized by connecting them to the pin terminal type terminal block in the case. •Model EH-VE is a derived type of Model EH-V305A (operation unit incorporated) to which a remote operation box is attached for remote operation. For 10A operation, select model EH-VE210D. »lf the magnetic force needs not be adiusted. select Model ES-M. Model ES-M operation box) ELECTRO CHUCK MASTER* [Application] Rectifies an input from an AC power source to DC and outputs it to the electromagnetic chuck. To eliminate the residual holding power of the electromagnetic chuck, the rapid automatic demagnetization function is activated. [Features] •An interlock circuit is incorporated. •Demagnetization is completed quickly by simply pressing the switch. The program has been designed to give a consistent demagnetizing effect within a short time. •Model ES-M305B can be used on both input voltages of 100 VAC and 200 VAC. •The noise resistance feature ensures consistent performance in certain noisy environment. •The DC output voltage is constant. •The fundamental functions required to control electromagnetic chucks are incorporated neatly. Precaution for use Model ES-M103B is a low-cost, readily available lype and therefore lacks some functions described above. Mounting Hole * 1 - Switch selection &lf the magnetic force needs to be adjusted, select Model EH. Model EST-I ELECTRO CHUCK MASTER* STAND [Application] A stand type mounting base that can be used for any types of small Chuck Masters such as ES-M305B and EH-V305A. [Features] •Self-standing and easy installation. •The mounting plate at the top rotates 360 degrees to enable adjustment after installation. •A rectifier can also be mounted. (mm(in)]
