11. Use only tools with shank diameter tolerance similar to the chuck I.D. tolerance.
12. Check if tools, chucks or chuck nuts are damaged before working.
13. When using NE260 continuously, refer to Continuous Area on Torque
Characteristics or check LOAD meter maximum (3 Green Lamps).
14. Attach the provided connector cover when not using Input/Output Connector
A/B or Selector Communication Connector.
15. Stop working immediately when abnormal rotations or unusual vibration are
observed.
16. Do not over tighten the chuck. This may cause spindle damage.
17. Select suitable products or tools for the applications. Do not exceed the
capabilities of the spindles or cutting tools.
18. When using Selector Unit with Control Unit NE260, please use E3200 Series
Selector Unit NE261.
19. Please don't touch the heat sink of Control Unit NE260. This may avoid scalding
yourself.
20. When using the Air Bearing Spindle, please need to supply the regulated air
pressure to the Air Bearing. When rotating the spindle with less the regulated air
pressure, this may make you damage to the spindle or the control unit.
FEATURES

(1) The E3200 system is designed to be mounted in a CNC lathe, robot, NC lathe or special
purpose machine for drilling, milling, slitting, grinding or other similar application.
(2) A high-speed brushless motor is used to achieve a maximum speed of 80,000 min
eliminate the nuisance of brush maintenance.
(3) Speed control and protection functions utilize a high performance microprocessor.
(4) Automatic control and monitoring of spindle functions are possible.
(5) Wide speed range, 1,000-80,000 min
(6) Compact control unit design allows easy installation in space restricted machines.
Connectors and control panel are front mounted for easy access.
(7) Control Unit is capable of being connected to AC100V to 240V power sources.
(8) Two types of control units are available. Standard type NE260 and NE260-OP1 which
conforms to European standards for safe, automatic machine operation.
(9) Gear Mode Select Switch installed. Set Gear Mode to display the rotating speed at the
cutting tool when using an angle spindle or speed reducer.

• The installed Safety Relay is designed to comply with EN standards, 'a' contacts switch the Motor Power Line
and 'b' contacts switch the external outputs to the machining center's controller.
• The Safety Relay utilizes Normally Open contacts. The Emergency Stop Signal lines must be supplied with
power to hold the Safety Relay contacts closed and allow the control unit to supply power to the motor. Any
system errors, trouble with the machining center or the connections between the E3000 control unit and the
machining center's controller will cause the relay contacts to open and the E3000 motor to stop.
• The Emergency Stop Signal Input can be connected to any and all portions of the machine's safety systems to
stop the E3000 motor any time that stoppage of the spindle and motor is required.
• The 'b' contact outputs can be used to detect an open circuit on the motor line and integrated with the
machines safety systems to stop the machine in case of trouble. If the 'a' contacts of the Safety Relay are
welded together by an over load or short circuit the 'b' contacts' separation is maintained at more than 0.5mm
spacing by the relay's spring release mechanism.
Note3 <Motor Speed Limited Area>
*
Limit motor speed depend on motor types. Before using it, check the specifications of the motor & the motor
spindle.
• Control to limit motor speed from 1,000 to 80,000 min
Motor Speed Area is from 20,000 to 80,000 min
• Control to limit motor speed from 1,000 to 60,000 min
and EM20-S6000.
• Control to limit motor speed from 1,000 to 50,000 min
• Control to limit motor speed from 1,000 to 32,000 min
