Cautions For Handling And Operation; Features - Nakanishi E3200 Series Operation Manual

Thank you for purchasing the E3200 Ultra-Precision, High-Speed spindle system. The NE261 was
designed for controlling multiple sequentially controlled spindles on CNC lathes, robots, NC
lathes and special purpose machines. The motor, spindle and control unit are designed to work
as an integrated system capable of 80,000 min
protect the spindle, please use an air line kit to ensure clean, dry, properly regulated air is
supplied to the motor and spindle. The E3200 system is capable of being used with coolants and
cutting lubricants. Please read this Operation Manual carefully prior to use.

CAUTIONS FOR HANDLING AND OPERATION

Read these cautions carefully and only use in the manner intended.
Safety instructions are intended to avoid potential hazards that could result in
personal injury or damage to the device. Safety instructions are classified as follows
in accordance with the seriousness of the risk.
Class
A hazard that could result in bodily injury or damage to the device if the safety
WARNING
instructions are not followed.
A hazard that could result in light or moderate bodily injury or damage to the
CAUTION
device if the safety instructions are not followed.
WARNING
1. The E3200 Series is not a hand tool. It is designed to be used on a NC lathe or
special purpose machine.
2. In the event of a malfunction or breakdown, grounding provides a path of least
resistance for electric current, reducing the risk of electric shock. This system is
equipped with an electric cord with a grounding conductor and a grounding plug.
The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordnances.
3. Don't use in dangerous environments. Protect the selector unit from moisture
and other contaminants. Failure to protect the selector unit can result in damage
to internal components and injury to the operator.
4. Always wear safety glasses. Everyday eyeglasses only have impact resistant
lenses, they are not safety glasses. Also use a dust or face mask whenever the
motor is running.
5. Ensure that the earth wire is properly grounded : failure to follow this warning
may result in electric shock or fire.
6. Check to ensure that the supply is the same as the control unit's rated voltage.

Degree of Risk
CAUTION
1. Motor cooling and Spindle purge air is required to operate the system.
Air hose must be connected to the Air in joint on the front of the control unit.
0.35MPa air must be supplied.
2. When errors occur and error lamp flashes, check and correct the cause of the
malfunction before continuing use. Failure to correct the problem will result in
damage to the unit and motor.
3. When the Warning Lamp on the control unit lights conditions exist that could
result in dangerous operation. Check operating conditions and continue use only
after correcting the problem.
4. Do not hit, drop or subject motor, spindle or control unit to shock as this will
cause damage to internal components and result in malfunctions.
5. The electric motor and spindle require air for cooling and protection : ensure that
this supply is clean, dry air. Introduction of dust, moisture or other contaminants
into the motor and spindle will cause damage to internal components.
6. When using NE260 continuously, refer to Continuous Area on Torque
Characteristics Graph or check the LOAD meter (3 Green Lamps).
7. Do not install system next to RF noise sources as malfunctions can occur.
If smoke, noise or strange odors emanate from the unit or motors immediately
turn off the power switch, disconnect and take to a NAKANISHI authorized
Dealer for service.
8. Stop working immediately when abnormal rotations or unusual vibration are
observed.
9. Do not place anything on NE261. This may cause damage to NE261.
10. Do not disassemble, modify or attempt to repair the unit or motor as it will
damage internal components and there are no user serviceable parts.
11. Attach the connector cap or air plug (Provided) when you don't use NE261.
12. When installing a motor/spindle to a fixed base, make sure the fixed base is
grounded in order to avoid the risk of an electric shock.

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. Up to 4 motors can be connected to NE261 providing individual control of each motor.
( 4 motors can't be run simultaneously )
3. External control signals and external monitoring can be done with the NE260 and NE261
combination. Control and monitoring input and output signals will all be connected to CN1
on the NE260.
4. Wide speed range, 1,000-80,000 min
5. Compact selector unit design allows easy installation in space restricted machines.
Connectors and control panel are front mounted for easy access.
6. Control Unit is capable of being connected to AC100V to 240V power sources.
-1 makes high precision machining possible.
