Use

The ENESKA 3-2 grinding, milling, and polishing system is used in tool and mould making and in

engineering workshops for surface ﬁ nishing.

Two micromotors are available with di erent speed and output ratings. The motors are driven

electrically via a control unit.

Together with various handpieces it is thus possible to select exactly the right combination for

any requirement and to suit any working use.

For recommended tools please see the joke catalogue section on “Driving motors and handpie-

ces”.

Describing of the operating elements of the control unit

Figure 7.1/1: Handpiece holder takes up the handpieces.

Figure 7.1/2: Forward/reverse selector switch

Select the direction of rotation with the forward/reverse selector switch. Each

time this switch is pressed, the direction changes. When the FWD./REV. is not

lit, it shows right hand rotation (FDW.).

Figure 7.1/4: The rotating regulator allows the rpm of the relevant micromotor to be inﬁ nitely

varied up to the maximum level 40,000 rpm (is equivalent to 40).

Figure 7.1/5: Memory Speed Function, Fixpeed

First with the motor stopped, preset the desired speed on the speed control

knob(7.1/4). Next press the ﬁ xpeed switch for more than 1 second . A „beep“

sound and the ﬁ xpeed LED will light. The motor is now set to run at the ﬁ xpeed

setting. To change ﬁ xpeed memory, repeat the above procedure.

Fixpeed memory cannot be set over 30,000 rpm!

Next press the memory function key for more than 1 second. A signal sounds and the LED display

(7.1/6) illuminates. The rpm now remains constant at the saved speed. One speed and one direc-

tion of rotation can be saved for each motor output, which is also retained after switching on the

control unit again:

• select the appropriate motor (7.1/14 or 7.1/10)

• adjust the speed (7.1/4)

• observe direction of rotation (7.1/2)

• press the memory key for more than 1 second.

The saved speed can be deleted by further pressing the memory key for more than 1 second. A

signal sounds. The LED display (7.1/6) is no longer illuminated.

When the ENESKA 3-2 system is shipped from the factory, the ﬁ xpeed is preset for both

motor A and B to 20,000 rpm.

If the foot pedal is used, the speed range can be varied with a saved rpm up to the set speed.

Commissioning the control unit and micromotors

1. Place the control unit in a suitable dry place. Usable temperature should be between 0°

and +40° C and relative humidity (RH) between 10 and 85 %.

2. Adapt the position, if required by pivoting the support arm (7.1/8).

3. Make sure the speed control knob (7.1/4) is set at the lowest speed position.

4. Connect the mains cable to the control unit and a 230 V socket. Place the unit for quick

access of power code (to disconnect in case of emergency).

5. If required, connect the foot switch (7.2/1) to the control unit by means of a cable.

6. Set the mains switch (7.1/7) to the „On“ position; the display of the rpm indicator

illuminates.

7. Select the direction with the forward/reverse switch (7.1/2). Each time this switch is

pressed, the direction changes. When the FWD/REV LED (7.1/3) is not lit, it shows “right

hand rotation”.

8. Connect the handpiece (consider the instruction manual of the handpiece). Insert the

motor cord plug into the motor A (7.1/15) or motor B connector (7.1/9) and tighten the

motor cord plug nut.

9. Choose between manual -, foot pedal operation or auto speed system to use the micro-

motor:

Manual operation

Set the rotation speed with the speed control knob (7.1/4) and check the speed on the

speed display. Select the desired motor by pressing either motor A (7.1/10) or B (7.1/14).

After selecting the motor either press the same button one more time, press the smart

switch (7.1/18) or the foot pedal again.

Foot pedal operation

The foot pedal is active in addition to manual mode as soon as it is connected to the

control unit. Set the speed and operate the foot switch in order to variably reach the

optimum speed.

Auto speed system

In order to ﬁx the speed, press the foot pedal until the desired speed is reached and

subsequently press the pushbutton of the required motor (7.1/14 or 7.1/10). The LED dis-

play for the motor illuminates. The speed is maintained even if the foot controller or foot

pedal is released. In order to quit the mode, either press once again the pushbutton for

motors A or B (7.1/14 or 7.1/10), the button on the handpiece (7.1/18) or the foot pedal.

10. This function is also active when the memory key is used. Plug a second connecting

cable with a micromotor into connection socket B if necessary. If you wish to toggle

between the micromotors, press the appropriate key (either 7.1/14 or B 7.1/10). The LED

display (7.1/13 or 11) indicates which micromotor is operating.

Connecting the handpiece to the micromotor

First screw the handpiece onto the micromotor by hand!

If you notice any resistance before the thread is screwed on as far as it ought to go, it means

that the drive shaft of the motor and the coupling on the handpiece are not ﬁ tting properly one

inside the other. In this case turn the shaft of the handpiece until the coupling notches into place.

Tighten the handpiece ﬁ rmly with a hook spanner.

Figure 7.3 Schematic drawing

Do not apply any force! This could cause irreparable damage to the motor bearings.

centre

Do not exceed 13 mm overhang for mounted grindstones. In case of overhang must exceed 13

mm reduce the motor speed in accordance with the following table:

Overhang (mm): 20, max. operating speed rpm: N x 0.5

Overhang (mm): 25, max. operating speed rpm: N x 0.3

Overhang (mm): 50, max. operating speed rpm: N x 0.1

Unscrewing the handpiece from the micromotor

The handpiece is screwed onto the mircromotor. A hook spanner is used for loosening.

Fuse replacement

Pull out the mains cable (7.2/3) from the socket.

The 230 V mains fuse is located behind the cover (7.2/2). Pull out the fuse holder on the rear of the

unit.

Replace the fuse. The fuse must comply with speciﬁ cation 250 Vac, T1A.

Additional functions

Tempomat key

An additional speed (less than the preset speed) can be set within the preset speed range using

the foot switch:

1. Press the button on the motor cable (7.1/18) for more than one second

2. The speed is saved and can be read on the display (7.1/4).

Memory function key (memory key)

The memory key makes it possible to save a speed and a direction of rotation (clockwise or

anticlockwise) for both channels (A or B). Set the desired speed using the rotary knob, in addition

to the direction of rotation.

Fixpeed memory cannot be set over 30,000 rpm.

Next press the memory function key for more than 1 second. A signal sounds and the LED display

(7.1/6) illuminates. The speed now remains constant however at the saved rpm.

One speed and one direction of rotation can be saved for each motor output, which is also retai-

ned after switching on the control unit again:

• select the appropriate motor (7.1/14 or 7.1/10)

• adjust the speed (7.1/4)

• observe direction of rotation (7.1/2)

• press the memory key for more than 1 second.

The saved speed can be deleted by further pressing the memory key for more than 1 second.

A signal sounds. The LED display (7.1/6) is no longer illuminated.

Maintenance/Care

Control unit

The unit does not require any maintenance. Clean it with a dry, soft cloth.

Handpieces

Clean the contact surfaces whenever you change the tool.

When you change the handpieces, check that the threads are clean.

Ensure absolute cleanliness when changing the collet and only use the spanners provided. Clean

up the collet one time/week.

Mircromotors

The brushless motor does not require any maintenance. All ball-bearings are encapsulated and

permanently lubricated.

Troubleshooting

The control unit is ﬁ tted with an over-load cut-out switch.

If the switch in the control unit has responded, the cause is likely to be:

The handpiece or the micromotor is continually being loaded at its maximum limit. In this case

wait for about 3 to 5 seconds. It will then be possible to resume operation
