Joe Kaminski Leave a comment

The Control Techniques UNI2403 Unidrive is a size 2 Unidrive with 5.5kW, 10HP, a 25A output and 19.8A input. The versatile Unidrive was the first universal AC drive capable of providing V/Hz, open, and closed loop vector, servo, and regen control in every unit. The unidrive combines all five of these AC drive technologies into one for the ease of the customer.

For quick setup of basic applications, the UNI2403‘s most common parameters are arrange in one main menu. There are hundreds of user-configurable functions that are separated into 20 logicial menus which provides quick setup for advanced apps.

Fanuc Motor Safety Procedures and Tips

Joe Kaminski Leave a comment
We have people ask about best practices for working with Fanuc motors all the time, so here are some Fanuc Motor Safety Procedures and Tips. For more info you can check out  all of our Fanuc products or email us at sales@mroelectric.com.
When working with servo motors:
•NEVER pick up or carry the motor by the cables or the shaft. (Always carry by the frame.) Use a crane or lift to move the motor when necessary.
•NEVER drop or subject the motor to impact. The servo motor is a precision device.
•NEVER set heavy or sharp objects on the motor or cables. Do not step or sit on the motor or cables.
•NEVER use a metal hammer on any part of the motor. If it is absolutely necessary to use a hammer, use a plastic hammer.
Keep the motor properly secured and away from the edge of the work area when servicing the motor, as a dropped motor could

cause personal injury or destroy the motor

Basic Motor Safety, Procedures, and Best Practices
• Be safely dressed when handling a motor.
Wear safety shoes and gloves. Avoid loose clothing which can get caught
on the motor. Be careful not to let hair get caught in the rotary section of the motor. Do not handle the motor with wet hands.
• Shut off the power before working on a motor. Wait at least 5 minutes after the motor is shut off before touching any
power terminals.
• Always use the correct cables. Centroid cables are shown in the motor compatibility table. Wiring diagrams and pin outs
for motors are provided in Appendix B.
• Ensure that the motor and motor related components are mounted securely. Ensure that the base or frame to which the
motor is mounted to is strong enough.
• Do not touch the rotary section of the motor when it is running unless instructed to.
• When attaching a component having inertia to the motor, ensure any imbalance between the motor and component is minimized.
• Be sure to attach a key to a motor with a keyed shaft.
• Use the motor in appropriate environmental conditions. Do not store flammables in close proximity to the motor. When
not in use, store the motor in a dry location between 0° to 40° C.
• Do not remove the nameplate from a motor

Upgrading From FANUC C Series Servo Amplifier to α Series

Joe Kaminski Leave a comment

If you experience a system failure due to a Fanuc C series servo amplifier, (A06B-6066-H002, H003 etc.) you may feel like your only option is to replace it with the same exact unit. However Fanuc also offers the α series servo amplifiers which features improvements over the C series. In most cases you can replace your C series servo amplifier with the α series servo amplifier that has the identical final four numbers of the C series model number. The chart below outlines this:

The advantages of replacing your C series amplifier with an α series amplifier are:

  • A built in power supply
  • A second interface, type B, as well as the more conventional type A interface
  • Updated power device, intelligent power module, to reduce power loss and increasing reliability

α series amplifiers are also designed with the same dimensions as the C series so that you can install them into your current system easier.

Go to our website to check out our selection of C series and α series FANUC amplifiers.

Fanuc A06B-6050-H103 Servo Jumper Settings

Joe Kaminski Leave a comment

When replacing a Fanuc A06B-6050-H103 Servo unit you should check to make sure the replacement servo has the same top board, part number A20B-1000-0560. After this part number there will be a “/” and then something similar to “05A” which denotes the revision of the board. Ideally you would match your original unit with a replacement unit that has the same board, but if that’s not possible then all you would need to do is reconfigure the jumpers on the board. The table below shows how to get this set up so you can get your servo back up and running right away. Search for more FANUC motors/drives on our website.

MRO Electric and Supply maintains a comprehensive stock of new and used FANUC CNC and FANUC Robots parts. If you need a FANUC replacement part, please call 800-691-8511 or email sales@mroelectric.com.
