GB

CAUTION!

Only use path-measuring systems recommended by OPTIMUM. When assembling the path-measuring systems imperatively follow the instructions of the manufacturer.

Before mounting it on the machine, check the operability of the measuring gauges. To do so, use the digital position display DPA 2000S or a similar device.

Install the measuring gauge in a way that it will not be damaged by cutting tools or coolants. If required, mount a cover.

If possible, mount the enclosed measuring gauges with the sealing lips showing downward.

If possible, place the reading head stationary in order to avoid damages of the connection lines by its movements.

CAUTION!

The path-measuring system and its add-on pieces can cover important components on the ma-chine tool (e.g. lubricating nipples).

Before mounting the path-measuring systems, please note such limitations in functions andmake arrangements accordingly.

3.3.4 Assembly of the reading head

Mount a fixture for the reading head.

Fix the reading head to the fixture.

Remove possibly existing assembly aids from the reading head.

Check the orientation of the reading head using a dial gauge (refer to the tolerances for the assembly given by the manufacturer).

Check if all components are moving freely.

3.4 Linking the position display to a frequency converter
The position display DPA 2000S is equipped with the function „cutting constant“ which allows toinfluence the spindle speed of a lathe in a way that the same cutting speed will result at the wor-king point of the tool independent from the workpiece radius.
To do so, the control of the DPA 2000S will directly influence the frequency converter (FC).

We mainly use frequency converters of the manufacturer LENZE for OPTIMUM lathes.Therefore, we will explain the linking of the DPA 2000S to this frequecy converter in detail below.

3.4.1 System requirements:

To operate only using the function „cutting constant“ a frequency converter (FC) having ananalog input 0 V - 10 V DC is required.

For an operation using the function „cutting constant“ for remaining options of the manual speedregulation, a frequency converter with two analog inputs is required:

0 V - 10 V DC for speed control via DPA 2000S (cutting constant control)0 V - 05 V DC for speed control via the potentiometer

The following items are required in addition:

ON/OFF switch to switch over between the manual speed setting and the cutting constant control

Assembly and commissioning Digital position display DPA 2000/ DPA 2000S ; Version 2.1.2


ON/OFF switch to switch over between the working ranges 1 and 2 for cutting constant opera-tion (refer to commissioning)Potentiometer for the manual speed setting (e.g. 1kΩ for frequency converters made by the manufacturer LENZE)Application module made by LENZE (type E 82 ZAFAC 001)Perforated disk for the speed recording (with 8 holes for small and 16 holes for large lathe chuck seats)Fork light barrier for speed recording

Please refer to the current OPTIMUM main catalog for optional accessories.

3.4.2 Electrical connection:

© 2011

G

The connection to the DPA 2000S is performed via the cable included in the delivery volumeusing SubD plugs - 15 pins (refer to page 11 paragraph 2.5)

1. Connect the grey cable (1) from the SubD plug to the black cable of the fork light barrier.2. Connect the brown cable (2) to the brown cable of the fork light barrier.3. Connect the blue cable (6) to the blue cable of the fork light barrier.4. Bridge over the green (3) and the blue cable (6).5. Connect the red cable (5) to the frequency converter at the input for the control voltage

(0 V - 10 V) 6. Connect the yellow cable (7) via the switch (NO switch) to the blue cable (6).7. Connect the white cable (9) for analog grounding GND to GND at the frequency converter

(for LENZE FU terminal 7).

Wiring diagram to connect the DPA 2000S on the following page

You need to set the maximum admissible speed of the lathe using the FC.

Danger! Do not exceed the maximum speed of the clamping devices. You can only make sure thelimitation of the maximum speed by using the FC. Set the frequency converter in a way that the maximum admissible speed of the clampingdevice will not be exceeded for both working ranges of the DPA 2000S.

In order to achieve the maximum possible speeds for the „cutting constant control“ which isresulting of the combination of your lathe with the position display it might be necessary to useclamping devices of a higher maximum speed.

If it is required to change over to manual speed setting an allpication module with two analoginputs will be additionally required. For programming data please refer to the attached manual.

Wiring diagram to connect the DPA 2000S



3.4.3 Programming the DPA 2000S

© 2011

G

When using the function „cutting constant“ the following settings of the parameters need to beprogrammed:

( „Internal parameter setting“ on page 5-36)

P19: Please enter the number of switchings on the fork light barrier per revolution (e.g.perforated disk with 8 holes = 8 switchings)

P20: Enter the value „1“ (recommended)

NOTE: The DPA 2000S supports two gear levels. Determine the two gear levels of your lathe in whichyou want to use the cutting constant functions. All control values which you have set on the DPA2000S are this way only referring to this gear level. For another gear level the modified transfor-mation will lead to deviations between the target value and the actual value, in particular forspindle speeds.

DANGER!If the lathe is operated in another gear level, the admissible maximum speed can beexceeded. This way, the retention force of the clamping devices will be reduced when thecentrifugal force is increasing. In doing so, the workpiece might get loose and fly off themachine.For your own safety use the cutting constant function only for the two selected gearlevels for which you have specified and entered the parameters.

To do so, determine the minimum and maximum speed of the selected gear levels.

Example:

Nominal speed of the gear level: 900 1/min

Set frequency range on the FC from 10 Hz to 50 Hz

Minimum speed for 10 Hz 180 1/min

Maximum speed for 50 Hz 900 1/min

P21: Enter the value of the maximum speed for the selected gear level 1.

P22: Enter the value of the minimum speed for the selected gear level 1.

P23: Enter the value of the maximum speed for the selected gear level 2.

P24: Enter the value of the minimum speed for the selected gear level 2.

When you have executed the above steps the commissioning of the DPA 2000S is terminated.

Switch over between the manual speed setting and the cutting constant control using the corres-ponding ON/OFF switch. The two switch settings need to be marked by the function markingswhich are being switched.
