What's the difference between the SUDX & the EUDX Series?	SUDX: D/C Servo Motor and Amplifier provides fast and dependable operations. However, the Speed and Torque ratings on D/C servos are Inversely proportional {In other words, the faster the speed the less torque produced - the slower the speed, the greater the torque.}	EUDX: Digital A/C Servo Motor and Amplifier provides Strong & Fast operations. The Speed and Torque ratings on A/C servos are Directly proportional {In other words, the faster the speed the greater the torque produced - the slower the speed, the weaker the torque.}

I don't see a keypad on the front of the UDNC control box. How do I Program the controller?

Does anybody really have the time these days to shut down production for 10 minutes to MDI (Manual Data Input) a program into the control box?

The UDNC series uses standard RS-232C ports to receive prewritten programs downloaded into it, just like you CNC & VMC does. Utilizing your existing shop computer, just install the Yuasa Terminal software, write and store your files, and download & save to the UDNC memory.

Don't have a computer in your shop? No problem, the SUDX series offers an optional Hand Held Computer Terminal (HCT-001 or HCT-002) and Terminal Interface Cable (TIC-002) for all your programming needs. You can write and save files offline, then plug in and download as you need.

Use your CNC com port and Macro Programming: Depending upon your CNC machines capabilities, many of todays controls {Fanuc, Mazak, Yasnac, Fadal, Okuma, Mitsubishi, Cincinnati, etc.} have the ability to send our programming statements right from their RS232 ports. That means you can actually write the UDNC program as part of your Macro and both machines can be programmed at the same time. With this method, you can be assured that the program move the rotary table makes is indeed the one it is supposed to be.

What's the main difference between Yuasa's Tables and those other guys?

Yuasa's Precision Craftsmanship Inside & Out

We use Dual Class "A" Tapered Roller Bearings for heavier radial, axial, and thrust loads instead of just a single radial bearing.
Dual Disc pnuematic braking provides upto 40% more brake torque for high speed, heavy milling operations.
Double lipped spring loaded oil seal around the spindle provides full protection from outside contamination getting inside, even EDM fluid!
Hardened & Ground steel worm shaft incased in an eccentric housing with dual needle and thrust bearings work together as an anti-backlash assembly.
High torque D/C and Digital A/C servos for whatever the situation may call for.

How many programs can I store inside the UDNC controller?

What are some of the Front Panel Features?

What are some of the Programming Features?

Up to 8 seperate programs can be stored in the controller and accessed from the front panel, (M, 0, 1 ~ 6).

Besides just program selection, you also have a FEEDRATE OVER-RIDE Knob that lets you manually over-ride your programmed feedrates in 10% increments (0%, 10%, 20% ~ 100%) SUDX (0 %, 10%, 20% ~ 120%) EUDX

LED Display for position/Block#/Step# & Error Messaging, Jog+/- Switch, Work Zero Set, Work Zero Return, Feed Hold, Machine Zero Return, Cycle Start, & a large red Emergency Stop Button.

Variable Feedrates Programming
Time Based programming for Helical Cuts
Absolute Moves (G90)
Incremental Moves (G91)
Arc Division (G72)
Loop Programming (G70)
Call to Sub or Program (G80 ~ G88)
Dwell (G04)
Continuous Movements without pause (M40)
Backlash Compensation (M38)
Position Reporting via RS-232 (Y or ?)
ENABLE & DISABLE Finish Signals (M18 ~ M21)
Plus Lots More

I've lost, damaged, or misplaced my Software &/or Manual; how do I get replacements? And what about updates?

Downloads of the current software and manuals are available on the main CNC Rotary Product page at No Charge.
