4.1 Mains connection

Prior to initial operation, make sure that the mains voltage agrees with the operating voltage stated on the milling motor's rating plate.

4.2 Selection of tools

Only use the collets/adapter sleeves listed in the chapter “Optional accessories”. Tools are selected depending on the materials to be processed and the capacity of the feed drives. Please take into account the milling motor capacity at maximum tool diameter and anticipated machining depth.

Danger Pull the power plug during all service work.

Wear protective gloves during a tool change. The insertion tool can get very hot during longer operation and/or the insertion tool’s cutting edges are sharp.

4.3.1 Tool clamping by means of collet

The spindle 1 (Fig. 1) of the milling and grinding motor is equipped with a precision collet 2 (Fig. 1) to hold the tools. The spindle lock is triggered by the locking button 4 and facilitates tightening and loosening of the union nut 3 (Fig. 1). Proceed as follows for the tool change: - Lock the spindle 1 (Fig. 1) to unclamp the tool by pressing the locking button 4 (Fig. 1). - Detach the union nut 3 with an open-ended spanner AF 17 or wrench ER 16 M. - Pull off the tool to the front. - Push the new tool into the tool holding fixture up to the limit stop. - Check the tool’s seat. - Spindle 1 (Fig. 1) is locked when the tool is clamped. - The union nut 3 is tightened with the open-ended spanner AF 17 / wrench ER 16 M.

Switch on the milling motor only when the lever 6 (Fig. 3) is not in the tool change position. Do not actuate lever 6 (Fig. 3) until the milling motor is at a standstill. The spindle 7 (Fig. 3) of the quick tool clamping device is equipped with a precision holding fixture for a tool shank Ø 8. Proceed as follows for the tool change:-27- - To unclamp the tool, move lever 6 (Fig. 3) forward up to the stop. - Pull off the tool to the front. - Push the new tool into the tool holding fixture up to the limit stop. - Check the tool’s seat. - To clamp the tool, move the lever back to its original position.

Danger To protect the thread, only screw the union nut 3 (Fig. 1) lightly onto the spindle 1 (Fig. 1), but do not tighten when no tool is inserted. Collet 2 (Fig 1.) could get pressed together too much and be damaged in the process.

4.4.1 Information on the use of collets:

- Please always use the correct milling cutter size for OZ8 collets (DIN 6388 / ISO 10897) and also for ER16 collets (DIN 6499 / DIN ISO 15488). - Please always click the collet into the union nut first, then insert the milling cutter. - If jammed, please loosen the collet with a square timber or rubber hammer with a light blow from behind (no metal tool!). - Please oil the collet collets at the beginning as well as after longer use as otherwise they can get stuck. - A significantly better concentricity can also be achieved by using a solid lubricant (e.g. Molykote P-40) or by lightly greasing the collets.

4.4.2 Recommended tightening torques (observe overall system)

Tightening torque for union nut / collet = 10 -11 Nm Tightening torque for clamping collar 43 mm = 7 Nm The Euro neck mount “V” should not be smaller than dimension “h” (Fig. 8). Dimension “h” amounts to 20 mm. Clamp the milling motor as far as possible across the entire mounting diameter in the Euro neck mount “V1” (Fig. 8). Tighten clamping screw „W“ with max. 7 Nm. (Fig. 9) As far as possible, avoid punctual clamping (for instance using a grub screw) in the Euro neck mount „V2“ (Fig. 10).

4.4.3 Maximum speed when using a collet adapter

The recommended maximum speed for the use of the collet chuck adapter OZ8 and the collet chuck adapter ER is max. 16000 rpm.-28- 5 Operation

5.1 Initial operation

Personnel entrusted to work with the milling motor must be made aware of the operating manual, calling particular attention to the chapter “Safety instructions”. This operating manual only deals with the milling motor and does not consider the installation situation. Please take note of any other operating manuals.

Push the power switch 5 (Fig. 1) forward until it engages. If the milling motor is connected to the mains voltage, the setting wheel X (Fig. 2) lights up in blue (BU) and the milling motor accelerates to the previously set speed after 0.2 s with a soft start. The duration of the soft start depends on the set speed and is approx. 1.2 s at maximum speed.

Push onto the rear end of the power switch 5 (Fig. 1). The switch audibly jumps back to off position. The lighting on the setting wheel X (Fig. 2) goes out and the motor coasts to a standstill.

With the design Y (Fig. 2) you can control the speed via the interface and automatically monitor the remaining runtime in the event of overload. To protect the user and the connected systems, the interface is electrically isolated from the power supply of the drive train (safety isolation). All signal and operating voltages refer to the reference potential “GND”. As soon as the supply pin “U

” of the interface is supplied with voltage in accordance with the specification, the milling motor switches to “portal mode”. The bottom status table 3 shows all possible control constellations. Input Output HS / - U

When the interface is not in use, protect it against dirt with the supplied covering cap Z (Fig. 4).

5.2.1 Assignment portal connector

All pins on the portal connector are protected against reverse polarity. At voltages above 30 V, continuous operation with reversed polarity must be avoided as this can lead to failure of the interface. Pin No. Parameter Colour of wire Order No.

With the setting wheel X (Fig. 2) you can adjust the speed continuously. The concrete speed values of individual stages can be found in the table on page 5 or on the speed sticker on the housing. Until the motor characteristic is reached, the built-in electronics readjust to the set speed.-30-

5.3.1 Speed setting in NC design

In “portal mode”, the position of the setting wheel X (Fig. 2) for the speed setting is ignored. The speed can only be changed by the voltage at the pin “U

“. If you wish to set the speed by means of the setting wheel X (Fig. 2), “portal mode” must first be deactivated by switching off the power supply at the pin “U

“ or by removing the control cable. The correlation between speed and control voltage is illustrated in formulae (1) and (2).

Danger If you carry out any work on the working spindle after the overload protection has triggered, the mains plug must first be removed. To protect the milling motor, the operating parameters current, speed and temperature are dynamically monitored and the power tool is switched off if necessary. Shortly before the overload protection is tripped, the illumination of the setting wheel X (Fig. 2) changes to a permanent red (RD). To put the milling motor back into operation, you must open and close power switch 5 (Fig. 1). The milling motor goes into operation and the illumination of the setting wheel X (Fig. 2) changes to blue (BU).

5.4.1 Optical display of the remaining runtime

Triggering of the overload protection during operation leads to breakage of the milling tool, damage to the workpiece or even damage to the portal system. You can prevent this by paying attention to the visual output signals at the setting wheel X (Fig. 2). As long as the milling motor is not overloaded in terms of performance, the setting wheel lights up permanently in blue (BU). If the milling motor is overloaded, the calculated remaining runtime is displayed flashing in red (RD). On page 6 (Fig. 7) you can see the temporal arrangement of the pulses in overload mode. The correlation between the flashing behaviour and the associated remaining runtime is shown in the bottom table 4 on page 31. If the remaining runtime is not sufficient for your application, reduce the load or feed rate to be able to switch back to continuous operation.

5.4.2 Display of the remaining runtime in the NC design

If the milling motor is in “portal mode”, the remaining runtime can be queried via the interface in addition to the visual display. The bottom table shows the correlation between the remaining runtime and the associated output variables.-31- Operating mode Remaining runtime /
