① A high-speed brushless motor is used to achieve extremely high speed and eliminate the nuisance of
brush maintenance.
② Motor speed is digitally displayed.
③ Wide motor speed range: 0-80,000min- .Cutting speed range is: 20,000-80,000min- .The motor
can also be set for 500 min- rotation for centering.
④ Automatic control and monitoring of spindle functions are possible.
⑤ Wide range of collet chucks is available.
⑥ The front panel of the E800Z control unit can be detached and the cord can be extended to Max.4m
with  the control panel extension cord  (option). This cord allows the control unit,s front panel to be
remotely mounted in a convenient location.
⑦ A safety relay is installed to conform to European safety standards.
The  a  contact is used for the electric line and the  b  contact output makes detection of an open
motor electric line circuit possible. This system can be integrated with the machine,s safety systems
to help enhance safe, automatic operation.
⑧ The Emergency Stop Signal can be used to operate the safety relay automatically. When the
Emergency Stop Signal circuit is open the power lines between the control unit and the electric motor
are disconnected.
⑨ E800Z is capable of being connected to 5V to 230V power sources. The control unit incorporates a
voltage selection switch; this switch is set to the proper position for the voltage being used.
