The 527F includes a NUC form factor PC that drives the pendant monitor in order to view CNC operation. This is not a PC control – it's simply using the PC to view 527F screens via software. The operator can minimize, maximize and scale the 527F screens like any other Windows program. 


A USB dongle connects to the NUC computer mounted inside the pendant. 527F screen information streams via USB and is displayed on the screen. A pendant mounted tray supports a customer proved wireless mouse and keyboard.

Run software on a PC with confidence knowing it cannot interfere with CNC  operation. The USB connection is one way and only screen data is sent from the 527F. 


Having a computer at the machine brings a host of possibilities along with confidence that the PC is not running any part of the CNC. , such as CAD/CAM programming at the machine, remote CNC viewing via TeamViewer/Google remote desktop, ability to check email, pulling files from anywhere on the network and placing them into the 527F memory... and is a nice way to perform program simulation using the software of your choice.

Extra Tool

The Extra Tool feature allows tool offset and diameter information to be defined with a unique tool number without regard to the tool changer pocket location. Unique tool numbers can be inserted into any tool changer pocket. When a tool is called from a program, the control will know which pocket it is in and insert it in the spindle.


This saves a tremendous amount of time by eliminating the need to re-sort tools and/or re-type diameter and offset information when changing tools from one job to another. Tools and their information will be retained even when removed from the tool changer. This makes replacing a removed tool due to limited tool changer size  a breeze. It allows makes it simple to move tools from one machine to another. 

Duplicate tools can be loaded into the tool changer. When used with the tool timer, a fresh tool can replace an expired tool at the next tool change. The time period is user defined.

Automatic Coolant Nozzle Control

The 527F serial port can be re-defined as a built in interface to programmable coolant nozzle systems that automatically and precisely aim high performance coolant jets at the cutting edge of each tool. It is as easy as entering SETP parameters, scrolling to the RS-232 parameter and selecting "SEND T# OUT RS232" to Yes . The 527F will then automatically send the current tool via the RS-232 port.

No need to add sensors to the nozzle system in order for it to keep track of which tool is being used or sending tool identification to the nozzle system with DPRINT statements. .




The acceleration ramp can be set individually for each axis. This can be used in cases where there is a large mass on the table and the X/Y should ramp longer without penalty in the Z axis only moves. The DELTA value specifies in INCHES PER MINUTE when the control will start performaing ramp control. The default setting are best for most applications.

The OIL setting determines the trigger time in minutes for PDI type units.

The legacy control allows the user to set a single orientation factor. This can be problematic in situations where the optimal setting for the low range is different that the best setting for the high range.

The 527F allows for a different orientation setting in both ranges which allows the user to optimize the setting during orientation. The increment setting provides fine tuning by allowing the user to set nominal resolution as well as the timeout before an alarm occurs.
