Pendant – Overview

Side Pendant

The NXGEN pendant is the key interface for the operation of the machine. In designing the new pendant, retaining the Legacy familiarity and functionality was first priority with a goal of a minimal operator training requirement.

However, it is not just a duplication, it has many hardware improvements on the inside.

Improvements:
– Wiring count from the control to the pendant has been reduced to about 1/3 of the Legacy
– Simplified Internal design reduced to minimal wiring and use of USB devices
– Low Power using only 5 and 12 VDC
– No High voltage AC in pendant eliminates potential electrical noise on logic signals
– Pendant components have an isolated ground to greatly reduce/eliminate ground loop potentials
– Less than 1/2 the weight of the Legacy pendant
– Same mounting hardware, designed to drop into existing hardware

Keyboard
The keyboard is a PC Style Keyboard –  panel mounted, IP64 rated seal with a very nice tactile feedback. To make it even better it has a backlit feature with the touch of a button the keys lite up for that extra bit of comfort.

Handwheel
It is a standard feature on the main pendant. Also, a remote handwheel option is available. The remote handwheel includes an axis and increment selector, Start, Slide Hold, Tool IN/OUT and ESTOP Buttons are featured on the remote handwheel.

Pots & Axis Selectors
While others attempt to recreate the Legacy using cheaper components, we use the identical switches and knobs. Using the same manufacture retains the exact feeling even though they cost a little more.

Memory Lock
Inhibits program modification the same as the Legacy

Spindle Load
LED backlit showing 0 to 150% spindle load.

Toggle Switches
Controls Block Skip, Optional Stop and Work Light functions with same ON/OFF labels.

Emergency Stop
Stops all operations and powers down the amplifier chassis. Release and press JOG to reset.

Rapid Travel
Selects between 25%, 50% and 100% of the rapid travel rate set in the parameters.

Feed Rate Pot
Exact same Pot as the Legacy, but now the range goes to 250%.

Spindle Pot
Exact same Pot as the Legacy, but now the range goes to 250%.

Axis Select
Exact same Pot and functionality as the Legacy. Selects X, Y, Z, A, B, AUX, REMOTE.

Increment
Exact same Pot and functionality as the Legacy. Increments .0001, .001, .01
Note: While in JOG pressing the T key selects .0000125″ step size.

Start
Exact same push button and functionality as the Legacy.

Slide Hold
Exact same push button and functionality as the Legacy.

USB Port
A quick and easy front mount, 500ma supply interface to a USB 2.0 device such as keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters.
Most commonly used for a Flash drive to load/save program data.
Besides the USB port on the front panel, there are more USB connections plus a Ethernet connection inside the main control box.

Waiting Light
Exact same functionality as the Legacy.

Like the Legacy, a standard QWERTY layout is used.  Having a Windows style keyboard provides both functionality and the easy use of the many software programs features such as shop floor and process automation.
The Panel Mount USB design greatly improves the simplicity inside the pendant.  Improvements such as simpler electronics, waterproof and dustproof design is a tremendous MTBF improvement.

Water and Grease Ready
Keyboard Closeup NXGEN Besides having a NEMA 4X seal, the keys are made of Industrial silicone rubber and have a nice tactile feel with a mechanical snap when pressed.
Backlit Keys For Dim Environments
The keyboard has a backlit feature that can be turned on with the push of one key. This backlighting makes the keyboard comfortable and is more functional to use in low-light environments.
